Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the control bar is made as a single rigid piece, then the structural strength is improved, but the adaptability to different user activities and terrain types deteriorates
Solution Approach 1:
The control bar is divided into multiple detachable segments that can be connected in various configurations. This segmentation allows the control bar to be reconfigured for different activities (skateboarding, snowboarding, biking) while maintaining structural integrity through proper connection mechanisms between segments.
Solution Approach 2:
The control bar transitions from a static rigid structure to a dynamic reconfigurable structure. The segments can be detached and reattached in different arrangements, allowing the control bar to adapt its shape and characteristics based on the specific activity and terrain requirements.
2Ease of manufacture
If the control bar is designed as a fixed configuration, then the manufacturing complexity is reduced, but the ease of operation for different activities deteriorates
Solution Approach 1:
By segmenting the control bar into standardized modules, each segment can be manufactured independently using simple processes. The segments are then connected through straightforward attachment mechanisms, maintaining manufacturing ease while enabling flexible reconfiguration for different operational needs.
Solution Approach 2:
The control bar segments are designed with universal connection interfaces that allow the same segments to be used across different activities and configurations. This multi-functionality enables ease of operation for various activities without requiring complex activity-specific components.
3Device complexity
If the control bar is made as a single piece, then the device complexity is reduced, but the portability and ease of storage deteriorates
Solution Approach 1:
The control bar is segmented into multiple detachable sections that can be separated for compact storage and transport. When not in use, the segments can be stored individually in a compact manner, significantly improving portability while maintaining relatively simple structural design through standardized connection points.
4Measurement precision
If the control bar uses complex steering mechanisms, then the precision of control is improved, but the ease of operation deteriorates
Solution Approach 1:
The control bar segments are designed to be self-aligning and self-adjusting through their connection mechanisms. The segments naturally orient themselves during use, providing intuitive control without requiring complex steering mechanisms or active adjustment by the user, thereby maintaining ease of operation.

AI summary
A control bar for removable attachment to a traction mechanism is formed by a plurality of elongated bar segments connected end to end, such that the control bar can be formed in a plurality of shapes, and is thereby adapted to be more easily manipulated by a user shifting their body weight to steer and maneuver the propulsion system.
