I can help you complete this assignment. Quick question: do you already have a specific problem statement or project topic from class? If not, below is a complete example you can adapt (includes 3+ individual ideas, a combined 5th idea, a Pugh chart comparing four ideas, written conclusion, and a final detailed sketch description). Use it as a template — change the problem statement and details to match your class project.
Example project (you can swap in your real problem statement)
Problem statement (example): Design a lightweight, portable laptop stand for students that improves ergonomics and cooling, is stable on different surfaces, and folds flat for easy transport.
1) Individual brainstorming — at least 3 ideas (each idea labeled and placed on its own page)
Note: For your submission, put each of the following on a separate page and hand-draw or create a digital sketch labeled as shown.
Sketch 1 — “Folding Triangular Stand”
- Description: Two identical triangular side plates connected by a hinge at the top and a crossbar at the bottom. Side plates fold flat against each other for transport. Crossbar has rubber strip for laptop grip. Open angle provides airflow underneath.
- Key features: rigid triangles for stability, two angle positions (shallow and steep), rubber feet, lightweight aluminum or ABS plastic.
- Materials suggestion: 2mm aluminum or reinforced plastic, rubber feet, pivot screw.
Sketch 2 — “Accordion/Scissor Column”
- Description: Scissor-like linked segments that expand vertically to set height. Collapses flat when closed. Top plate tilts slightly forward. Vents or cutouts in top plate for cooling.
- Key features: many discrete height positions, compact folded profile, composite plastic or thin aluminum links.
- Materials suggestion: injection-molded polycarbonate links, small metal pins.
Sketch 3 — “Hinged Base with Removable Backrest”
- Description: Flat base that sits on the table and a hinged backrest that swings up to support the laptop. Backrest locks into several stop positions. Base stores a removable thin aluminum heat-dissipation plate.
- Key features: very flat when closed, easy slide-in storage of heat plate, simple mechanism.
- Materials suggestion: bamboo or ABS base, metal hinge with detents.
Sketch 4 — “Adjustable Strap + Frame”
- Description: Minimalist tubular frame that supports the laptop with adjustable strap tension to change angle. Frame collapses into a band shape for carrying.
- Key features: ultra-light, few parts, uses strap tension as adjustable mechanism, breathable frame.
- Materials suggestion: anodized aluminum frame + nylon strap.
(Each of the above must be drawn on its own page and labeled “Sketch 1”, “Sketch 2”, etc., with a front view, side view, and a small labeled callout of materials/dimensions.)
2) Group discussion + combined idea (5th idea)
- After discussing pros/cons of the above, we combined the best features: stability of the triangular stand + multi-position adjustability of scissor column + flat storage of the hinged base.
- New combined idea (Sketch 5 — “Hybrid Foldable Tri-Scissor Stand”): Two triangular side plates like Sketch 1, but instead of a single hinge angle they include a built-in scissor-like adjustable linkage that clicks into multiple height positions. The bottom crossbar is removable and doubles as the flat heat-dissipation plate for storage (from Sketch 3). When folded, the side plates and crossbar lie flat and lock together with a small clip.
- Sketch 5 should be on its own page, labeled and showing folded and open states, and a small exploded view of the removable crossbar.
3) Pugh Chart creation (everyone makes one on their own page)
- Pick four ideas to compare. Label them #1–#4.
- Example selection:
#1 = Folding Triangular Stand (Sketch 1)
#2 = Accordion/Scissor Column (Sketch 2)
#3 = Hinged Base with Removable Backrest (Sketch 3)
#4 = Hybrid Foldable Tri-Scissor Stand (Sketch 5 — combined idea)
- Choose criteria that support the problem statement. Suggested criteria (you can adjust to your project):
- Portability (folded thickness & weight)
- Stability (prevents wobble)
- Adjustability (range of viewing heights/angles)
- Cooling (airflow or heat-dissipation)
- Ease of manufacture (cost and simplicity)
- Durability (wear at hinges/pivots)
- Cost (estimated BOM cost)
- Create the Pugh chart on its own page with a datum. Use one of the ideas as datum (for example #1 Folding Triangular = datum). For each other idea, mark + (better than datum), S (same), or - (worse). Below is an example filled chart and rationale.
Example Pugh chart (datum = #1 Folding Triangular)
Criteria: Portability | Stability | Adjustability | Cooling | Ease of manufacture | Durability | Cost
#1 (datum): all S (same)
#2 (Accordion/Scissor): Portability = + (folds small); Stability = - (many joints can wobble); Adjustability = + (many positions); Cooling = + (cutouts); Ease of manufacture = - (complex links); Durability = - (pin wear); Cost = - (more parts)
#3 (Hinged Base): Portability = + (very flat); Stability = S (decent); Adjustability = - (limited positions); Cooling = - (less airflow unless heat plate used); Ease of manufacture = + (simple hinge); Durability = + (fewer moving parts); Cost = + (cheap)
#4 (Hybrid Tri-Scissor): Portability = S (folds relatively flat); Stability = + (triangular geometry improves stability); Adjustability = + (scissor linkage provides multiple positions); Cooling = + (open structure + removable heat plate); Ease of manufacture = - (more complex than #1); Durability = S (hinges and scissor joints designed robustly) ; Cost = - (more parts but still reasonable)
Talk-through (how to rate each build — write these comments on the Pugh chart page):
- #2 scored well on adjustability and portability but loses on stability and durability because many moving pins can develop play.
- #3 is simplest and cheapest but lacks sufficient adjustability and airflow for good cooling.
- #4 combines strengths: stability and adjustability and cooling are improved; trade-offs are slightly higher manufacturing complexity and cost.
4) Your OWN conclusion to the Pugh chart
Write a short personal conclusion (on its own page):
- Example conclusion:
"Based on the Pugh chart, I select idea #4 (Hybrid Foldable Tri-Scissor Stand) as the best overall design because it balances stability, adjustability, and cooling while still folding flat enough for portability. Although it is slightly more complex to manufacture than the simplest hinged base, its user benefits (multiple height positions and improved laptop cooling) justify the added complexity. I recommend focusing on simplifying the scissor linkage and using durable metal bushings at pivots to improve longevity and keep costs reasonable."
5) Final design sketch (everyone creates their own labeled detailed sketch)
- Requirements: Everyone makes their own labeled, detailed sketch on its own page. Include:
- Front, side, and top views.
- Dimensions (example: folded thickness 12 mm, open height range 25–150 mm, tilt angles 5°, 15°, 25°).
- Materials and thicknesses (e.g., side plates: 2 mm aluminum; crossbar: 3 mm aluminum with silicone strip; pivot pins: stainless steel).
- Exploded detail of hinge/scissor joint with labels for fasteners, bushings, and any locking detents.
- Notes for manufacturing (CNC cut side plates, injection molded bushings, anodize finish).
- User instructions: how to fold/unfold and attach the removable crossbar heat plate.
When everyone is done
- Combine all individual sketch pages into ONE document (PDF) with pages in this order:
1. Cover page with group name, problem statement
2. Individual Sketch pages (Sketch 1, Sketch 2, Sketch 3, Sketch 4)
3. Combined Sketch (Sketch 5)
4. Pugh chart page (each team member should also have their own Pugh chart PDF)
5. Personal conclusion page (each member’s conclusion can be appended)
6. Final detailed design sketch page (each member’s)
Checklist before showing Mrs. Walder
- Each sketch is labeled and on its own page.
- Pugh chart is complete and on its own page.
- Your personal conclusion is on its own page.
- Final design sketch is detailed, labeled, and on its own page.
- ONE combined PDF contains all sketches and required pages.
If you want, I can:
- Convert the example ideas into a printable one-page per sketch PDF layout (text + sketch placeholders) that you can print and draw on.
- Customize all of the above to your specific problem statement.
- Produce a ready-to-print Pugh chart template you can fill by hand.
Which would you like me to do next: adapt this to your actual problem statement, or make the printable templates?
