Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If invasive surgery is used to treat Peyronie's disease, then treatment efficacy may be improved, but patient pain and procedural complexity increase
Solution Approach 1:
The patent replaces invasive mechanical surgical intervention with a non-invasive shock wave therapy system. The shock wave generator delivers focused acoustic energy through a water medium and gel interface, eliminating the need for incisions, sutures, and general anesthesia while achieving therapeutic effects on fibrous plaques.
Solution Approach 2:
The patent introduces water and contact gel as intermediary media between the shock wave generator and the penis tissue. This intermediary system allows transmission of shock wave energy without direct contact or invasive penetration, reducing patient pain and procedural trauma while maintaining treatment efficacy.
2Object-affected harmful factors
If drug therapy is used to treat Peyronie's disease, then patient comfort is maintained, but treatment efficacy becomes uncertain
Solution Approach 1:
The patent changes the therapeutic parameter from chemical (drugs) to physical (shock wave energy). By controlling parameters such as shock wave intensity, focal point positioning, and treatment duration, the system achieves reliable and predictable treatment outcomes without the uncertainty associated with pharmacological therapy.
Solution Approach 2:
The patent substitutes chemical drug therapy with a physical shock wave mechanism. The focused acoustic energy directly targets fibrous plaques to promote tissue remodeling and plaque dissolution, providing a more reliable and mechanism-based treatment approach compared to systemic or local drug administration.
3Object-affected harmful factors
If non-invasive shock wave therapy is used without precise positioning, then patient comfort is maintained, but shock wave energy delivery precision deteriorates
Solution Approach 1:
The patent employs a spheroidal reflector geometry to focus shock wave energy precisely at a second focal point. The curved reflective surface converges acoustic waves from multiple angles to a single target location, achieving high energy concentration and positioning accuracy without requiring invasive procedures.
Solution Approach 2:
The patent incorporates optical indicators and measurement devices to monitor and verify the position of the second focal point relative to the fibrous plaque. This feedback mechanism allows real-time adjustment of the shock wave generator position to ensure accurate targeting while maintaining patient comfort through non-invasive operation.
4Manufacturing precision
If focused shock wave therapy with precise positioning is implemented, then treatment precision is improved, but device complexity increases
Solution Approach 1:
The patent integrates multiple functions into a unified shock wave therapy system. The device combines shock wave generation, spheroidal reflection for focusing, water medium containment, gel application, optical positioning indicators, and mechanical stabilization into a single multi-functional apparatus, reducing the need for separate equipment while achieving high positioning precision.
Solution Approach 2:
The patent merges the aiming mechanism and fixation system with the shock wave generator housing. The cylindrical body serves both as a structural support for the generator and as a positioning device that stabilizes the penis. The water valve and gel application system are integrated into the same housing, simplifying the overall device architecture while maintaining precise targeting capability.

Function Achieved in This Case
This solution allows for precise and pain-free delivery of shock wave energy to fibrous plaques, improving treatment efficacy by stabilizing the penis and accurately targeting the shock wave energy, thus overcoming the limitations of invasive surgery and drug therapy.
Implementation Method 1
The shock waves originate in the shock wave generator. In electro-hydraulic applicators, the shock wave propagates in the hydraulic medium as a radial wave towards the reflector. Each beam of the shock wave bounces off it, passing through the hydraulic medium, the rubber bag, the contact gel, into the tissues, and within them up to the secondary focal point
