Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If low pressure gas sources are used in ballistic shockwave systems, then device complexity is reduced, but tissue penetration capability deteriorates
Solution Approach 1:
The patent increases the pressure parameter of the gas source from conventional low pressure (1-6 bar) to high pressure (50-100 bar), which directly increases the projectile acceleration and collision energy, thereby improving tissue penetration capability while maintaining the ballistic mechanism's simplicity
2Quantity of substance
If low pressure gas sources are used in ballistic shockwave systems, then operating costs are reduced, but treatment area size deteriorates
Solution Approach 1:
By increasing the gas pressure parameter to 50-100 bar, the projectile achieves higher velocity and energy upon collision, expanding the shockwave generation capability and treating larger tissue areas, which addresses the limitation of small treatment zones in low-pressure systems
3Device complexity
If low pressure gas sources are used in ballistic shockwave systems, then device simplicity is maintained, but re-treatment frequency increases
Solution Approach 1:
The elevated pressure parameter (50-100 bar) generates more energetic shockwaves that achieve better treatment outcomes in fewer sessions, reducing the need for frequent re-treatments while preserving the mechanical simplicity of the ballistic system
4Weight of moving object
If low pressure gas sources are used in ballistic shockwave systems, then device portability is improved, but treatment efficacy deteriorates
Solution Approach 1:
The patent achieves high treatment efficacy through increased pressure parameters (50-100 bar) that generate sufficient collision energy for effective shockwave production, while the portable design with integrated high-pressure gas cylinder and lightweight components maintains system mobility
