Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional stilts adjust legs individually using manual support methods, then the structure remains simple, but multiple adjustments are required causing safety risks and user discomfort
Solution Approach 1:
The patent applies pneumatic technology by using air-filled cylinders within the stilt legs. When air is pumped into these cylinders, they expand to lift the stilt platform synchronously. This pneumatic mechanism eliminates the need for multiple manual adjustments while ensuring stable and safe elevation, directly resolving the contradiction between ease of operation and user safety.
2Adaptability or versatility
If the lifting platform is positioned offset from the support point, then the structure allows for mechanical adjustment, but unbalanced forces create torque causing discomfort and instability
Solution Approach 1:
The patent addresses the force balance issue by strategically positioning the lifting platform and support points in specific asymmetric locations. The platform is placed on one side of the support rod while the support point is positioned differently, creating a controlled asymmetric structure. This asymmetric design allows the unbalanced forces to be distributed in a way that prevents harmful torque while maintaining adjustable height capability.
3Device complexity
If multiple manual adjustments are performed to achieve proper stilt alignment, then the structure remains mechanically simple, but the process consumes excessive time and creates safety hazards
Solution Approach 1:
The patent implements preliminary action by pre-positioning the lifting platform and support structures in optimized locations before use. The pneumatic cylinders are pre-installed within the stilt legs, and the support points are pre-configured at appropriate distances from the platform. This preliminary configuration eliminates the need for multiple iterative adjustments during actual use, significantly reducing adjustment time while maintaining mechanical simplicity.
