Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a laser beam is reacted to a shock wave generating medium to generate shock waves, then shock wave therapy can be performed, but the shock waves cannot be effectively transmitted to the target object
Solution Approach 1:
The patent introduces a shock wave transmission unit as an intermediary component between the shock wave generating medium and the target object. This transmission unit includes a transmission medium that facilitates effective shock wave transmission, solving the problem of ineffective transmission by adding a dedicated intermediary structure optimized for shock wave propagation.
Solution Approach 2:
The patent employs a buffer unit that changes the intensity parameter of the generated shock waves before transmission. By adjusting the shock wave intensity through the buffer unit, the system optimizes transmission effectiveness while preventing excessive energy loss, thereby improving overall therapy delivery efficiency.
2Force
If shock waves are generated with high intensity, then therapy effect is improved, but the shock waves cannot be transmitted effectively to deep targets
Solution Approach 1:
The patent divides the transmission system into segmented functional components: a shock wave generating section, a buffer unit for intensity control, and a shock wave transmission unit for directed transmission. This segmentation allows independent optimization of each function, enabling high intensity generation while maintaining effective transmission to deep targets through specialized transmission media and buffering mechanisms.
3Length of stationary object
If a buffer unit is added to reduce shock wave intensity, then transmission depth is improved, but device complexity increases
Solution Approach 1:
The buffer unit is designed as a thin-film or shell-like structure that can be integrated into the existing device architecture. This flexible design approach reduces the added complexity while maintaining the shock wave intensity reduction function, allowing deep transmission capability without proportionally increasing structural complexity.
