• Capacity to carry maximum load of 200 kg (apart from its own weight)
• A maximum speed limit of 5 km/hr

You are free to add other parts and accessories to it in order to make it a complete and stable product.

Part A: Using this platform, imagine and sketch 3 ideas for its use in a hospital environment.

Part B: Further, develop one idea as a concept for actual implementation and:

• List down 10 critical factors you will consider in your design.
• Sketch and explain your concept for its functional details, features, and usage.
• Suggest/indicate the materials and processes to manufacture the product.
• Write a brief note explaining the concept and list the design decisions taken.

Evaluation criteria:

• Critical thinking, identification of user needs and understanding of the context
• Problem solving and appropriateness of the solution
• Ability to explain details and features, sketching, presentation, and articulation
• Knowledge of materials and processes
  
  

Answer 1

Part A:

• Idea 1: Mobile Patient Transport Unit
  • The platform can be used to create a mobile patient transport unit. The design will incorporate a stretcher platform that can carry patients within the hospital.
  • Additional features like an IV stand, oxygen tank holder, and emergency buttons can be added.
• Idea 2: Delivery Cart for Hospital Supplies
  • The platform can serve as a base for a delivery cart to transport hospital supplies across the premises.
  • It will have several adjustable compartments for different medical supplies.
  • It will feature an ergonomic design for ease of handling and navigation.
• Idea 3: Waste Disposal System
  • The chassis can be used as the base for a medical waste disposal unit.
  • It will include sealed containers for hazardous waste with safe disposal mechanisms.
  • The platform will have a system for safely moving waste bins from one area to another.

Part B: Selected Concept - Mobile Patient Transport Unit

Critical Factors to Consider:

1. Ergonomics of the design for both the patient and healthcare workers.
2. Stability and balance while moving the unit to prevent tipping.
3. Smoothness of motion to ensure comfort for the patient.
4. Durability of the materials used to withstand hospital environments.
5. Safety features to secure the patient, such as adjustable sides and safety straps.
6. Battery life for the motor to operate effectively within the hospital environment.
7. Easy maintenance and cleaning of the platform.
8. Flexibility of the design to fit various hospital bed sizes.
9. Noise reduction for a quiet and peaceful environment.
10. Cost-effectiveness of manufacturing and maintenance.

Sketch and Explanation:

Materials and Manufacturing Process:

• The main chassis will be made from lightweight, durable aluminum alloy to ensure strength while keeping the weight manageable.
• The wheels will be made from rubber to ensure smooth movement and minimize noise.
• The platform will have non-slip surfaces for patient safety.
• The motor and battery system will be chosen to ensure low energy consumption and quiet operation.

Design Decisions Taken:

• A sturdy and compact frame design was chosen to ensure stability and patient safety.
• Adjustable sides were incorporated to allow for a secure fit around patients of different sizes.
• The motorized system was designed to ensure smooth transport with minimal effort for hospital staff.
• The battery was chosen for its long lifespan to last throughout a typical hospital shift.

Evaluation:

This design addresses critical needs in a hospital environment, where mobility, safety, and comfort for patients are paramount. The choice of materials and processes reflects the need for durability, ease of use, and minimal maintenance, making the product both functional and practical in a healthcare setting.
