Question:

Cities have a large number of vendors who move around selling various commodities. Due to the lack of dedicated space to sell, many vendors prefer to move around using hand carts and other accessories. Design a system or set of accessories to be used along with the existing bicycles, which the vendor can use to move around and sell toys for kids.
The vendor should be able to display and sell the products when stationary/parked; as well as pack up and move. Consider ease of assembly, material \& manufacturing processes, ease of use, user-friendly display, and ease of opening and packing up.
Instructions:

Present rough sketches of design alternatives.
Present your final design concept with a neat sketch showing all the details.
Indicate the materials and processes used.
Support your design with a brief note on the design decisions taken.
Your solution will be evaluated for:

Originality and innovative use of material in constrained situations.
Ability to understand the needs of the seller and buyers in the given situation.
Appropriateness of material and processes, assembly, manufacturing process, deployment and transportation issues.
Ability to articulate design decisions and effectiveness of presentation.

Show Hint

When designing products for constrained environments, prioritize portability, ease of assembly, and user convenience. Focus on lightweight, durable materials and modular designs for maximum adaptability.

Solution and Explanation

The idea is to design a system that is adaptable to an existing bicycle for vendors who need a mobile display and sales unit for their products, specifically for toys for kids. The system should allow the vendor to display products when stationary and pack up easily when moving.
Design Alternatives:


Alternative 1: Foldable display stand – A foldable stand with compartments for toys and a display surface.
Alternative 2: Modular cart system – A modular system that can be attached to the bicycle, with removable sections for easy packing and unpacking.
Alternative 3: Rolling drawer system – A system with drawers that can roll out from the back of the bicycle, allowing easy access and display of products.
Final Design Concept:
The final design combines a foldable display stand and modular cart system, where each section of the cart can be folded or expanded as needed. The cart has small wheels for easy movement, and the compartments are designed to hold different types of toys securely. The bicycle also has a special rack for mounting the cart and easy access to the products when stationary.
Materials and Processes:
The cart and display system are made of lightweight, durable materials such as aluminum and high-quality plastic. The folding mechanism uses simple hinges and locking systems for easy setup and packing. The bicycle attachment uses a quick-release clamp for easy mounting and removal.
Design Decisions:
The choice of materials was influenced by the need for lightweight and durable components that could withstand outdoor conditions. The folding design ensures that the vendor can easily set up and pack up without wasting time. The modular cart allows for flexibility in storing and displaying different types of toys.
