Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If specialized furniture for bathrooms and toilets is supplied with rigidly mounted legs, then the product is stable and easy to manufacture, but it requires a lot of space during transport and storage
Solution Approach 1:
The furniture is divided into separate components: a seat unit and leg assemblies that can be detached. The legs can be removed or folded, allowing the seat to be transported in a compact form while maintaining stability when assembled for use.
Solution Approach 2:
The leg assemblies are designed to be movable rather than fixed, allowing them to be attached when stability is needed and detached or folded when space is required for transport or storage.
2Volume of moving object
If specialized furniture for bathrooms and toilets is supplied with separately supplied legs, then the product is portable, but it requires assembly and disassembly by the customer with tools
Solution Approach 1:
The furniture incorporates self-assembling features where components can be easily connected without tools. The design allows users to assemble or disassemble the furniture by simple manual operations, eliminating the need for tools or complex assembly procedures.
3Adaptability or versatility
If multiple specialized appliances are provided for supporting a user in different situations, then the user can perform various tasks, but it increases the complexity of handling and storage
Solution Approach 1:
The furniture is designed as a multi-functional unit that can serve as both a toilet seat and a shower seat. By integrating multiple functions into a single piece of furniture with removable legs, the design eliminates the need for separate specialized appliances, thereby reducing handling and storage complexity while maintaining versatility.
