Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a collar or chest brace is used with the traction leash, then the pet can be controlled, but the wearing process becomes complicated and requires multiple accessories
Solution Approach 1:
The patent combines the collar and chest brace functions into a single integrated traction leash structure. The leash body forms a closed loop that simultaneously encircles the pet's neck and chest, eliminating the need for separate collar and chest brace accessories while maintaining control effectiveness.
Solution Approach 2:
The traction leash is designed to perform multiple functions: it acts as both a collar for neck control and a chest brace for chest restraint. The single device provides dual functionality, reducing accessory count while ensuring reliable pet control during walking.
2Adaptability or versatility
If an adjusting buckle is placed on the neck and chest for length adjustment, then the leash can be adapted to different sizes, but the comfort deteriorates and the adjustment range is limited
Solution Approach 1:
The leash body incorporates a dynamic adjustment mechanism that allows the closed loop to be easily resized. The adjustable section enables the leash to adapt to different pet sizes and growth stages, providing wide size adaptability while maintaining comfort through smooth material and ergonomic design.
