Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a personal vehicle is used for transportation, then mobility and convenience are improved, but the ability to accommodate baggage deteriorates due to limited space
Solution Approach 1:
The storage system is divided into a stay unit (fixed on vehicle) and a storage unit (removable container), allowing the storage capacity to be separated from the vehicle body. This enables the storage unit to be transferred between different vehicles including personal vehicles, effectively solving the limited baggage space problem while maintaining vehicle mobility.
Solution Approach 2:
The storage unit is designed to be universally compatible with multiple vehicle types through the coupling unit that can be mounted on various vehicle surfaces. The same storage unit can be used across different personal vehicles or transferred from general vehicles to personal vehicles, providing versatile baggage accommodation without compromising the mobility benefits of personal vehicles.
2Adaptability or versatility
If baggage is transferred from general vehicle to personal vehicle, then usability of personal vehicle is improved, but the operation becomes cumbersome due to manual transfer process
Solution Approach 1:
The coupling unit is pre-installed on the personal vehicle, and the storage unit is designed with predetermined coupling interfaces. This preliminary preparation allows for quick and easy attachment of the storage unit to the vehicle without requiring manual transfer or complex installation procedures, significantly improving the ease of operation while maintaining high adaptability.
3Volume of moving object
If a storage system is added to personal vehicle, then baggage accommodation is improved, but the device complexity increases due to additional components
Solution Approach 1:
By segmenting the storage system into a fixed stay unit and a removable storage unit, the complexity is distributed. The stay unit contains only the essential coupling mechanism mounted on the vehicle, while the storage unit is a self-contained module that can be independently manufactured and assembled, reducing the overall system complexity compared to an integrated storage solution.
Solution Approach 2:
The coupling unit is integrated within the stay unit structure, with coupling components nested within the housing. This nesting approach consolidates multiple functions into compact arrangements, minimizing the additional space and structural complexity required while still providing effective baggage accommodation.
4Reliability
If a coupling mechanism is provided to attach storage unit, then security of storage is improved, but the device complexity increases due to additional coupling components
Solution Approach 1:
The coupling unit combines multiple coupling functions (attachment, detachment, and securing) into a single integrated mechanism. By merging these functions into one compact unit with coordinated components, the system achieves high storage security while minimizing the number of separate parts and reducing overall structural complexity compared to multiple independent coupling mechanisms.
