Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single steering mechanism is used, then the device complexity is reduced, but the adaptability is limited and cannot support multiple driving modes
Solution Approach 1:
The steering driving device integrates both manual hand operation and foot-controlled operation into a single unified system. The handle assembly can be operated by hands for normal steering, while the foot-controlled mechanism provides an alternative driving mode. This multi-functional design allows one steering system to serve multiple purposes and support different user needs without requiring separate independent steering mechanisms.
Solution Approach 2:
The patent combines the manual steering mechanism and foot-controlled steering mechanism into a single integrated steering driving device. Both mechanisms share common components including the handle assembly, steering shaft, and transmission structure. The foot-controlled mechanism is merged with the existing manual steering system rather than being implemented as a separate independent system, thereby reducing overall device complexity while achieving multi-mode operation.
2Adaptability or versatility
If a foot-controlled mechanism is added to enable alternative driving mode, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The foot-controlled mechanism is nested within the existing manual steering structure. The foot-controlled pedals are positioned inside or integrated with the handle assembly, and the transmission path of the foot-controlled mechanism shares components with the manual steering system. This nesting approach allows the additional foot-controlled functionality to be incorporated without proportionally increasing the overall system complexity.
Solution Approach 2:
The steering shaft acts as an intermediary component that receives input from both manual hand operation and foot-controlled operation. Both driving modes converge at the steering shaft, which then transmits the combined steering input to the vehicle's steering system. This intermediary structure allows multiple input sources to be integrated through a single transmission path, reducing the need for separate complete steering systems for each mode.
3Adaptability or versatility
If multiple driving mechanisms are integrated, then the adaptability is improved, but the volume of the vehicle increases
Solution Approach 1:
Both manual and foot-controlled driving mechanisms share common structural components including the handle assembly, steering shaft, and transmission elements. By merging these mechanisms and eliminating redundant components, the overall space required for the steering system is minimized, allowing multi-mode operation without proportionally increasing vehicle volume.
Solution Approach 2:
The foot-controlled mechanism is nested within the space occupied by the manual steering components. The pedals and associated linkages are positioned inside or alongside the handle assembly structure, utilizing existing spatial envelope rather than requiring additional external space. This nesting arrangement enables dual-mode steering functionality within a compact volume.
