This project took our R&D team into a completely new category. A client asked us to develop a pneumatic (air-compressed) shockwave therapy device, a much larger machine than anything we had built before. After more than 8 months of development and testing, the client approved the samples and placed a mass production order.
| Challenge | Developing a large physiotherapy device from scratch |
| Product | Pneumatic (air-compressed) shockwave therapy device |
| R&D period | 8+ months of repeated testing and validation |
| Prototypes | 5 functional prototypes for in-depth study |
| Aging test | 5–8 million cycles per unit (simulating 3–5 years of use) |
| Result | Mass production order confirmed, entry into the shockwave market |
▎The challenge
Our R&D team had never built a therapy device of this size. With the client's guidance, we bought 3 best-selling shockwave devices from the market and took them apart. Teardown analysis and user feedback revealed three common failures:
• Projectile jamming: the projectile inside the handpiece gets stuck.
• Air hose leakage: poor air-tightness causes pressure loss.
• Compressor weakness: after a period of use, pressure drops and the compressor becomes noisy and overheats.
▎Root causes and our solutions
| Problem | Root cause | Our solution |
| Projectile jamming | Rough inner tube wall and poor projectile material cause too much friction | Tested multiple metals to find the best balance of hardness and toughness; precision-polished the inner tube wall |
| Air hose leakage | Standard hoses cannot withstand high pressure | Custom hoses from a high-end aviation hose supplier: bend-resistant with zero leakage |
| Compressor weakness | Pump performance declines over time | Screened multiple suppliers for the best combination of power, lifespan, noise and temperature |
| Unstable air pressure | Over- and under-pressure shorten the machine's life | Developed a pressure-holding and stabilising program for constant output |
| Overheating | High-intensity use generates a lot of heat | Condenser plus dual fans keep full-load temperature below 40°C |
▎How we worked together
1. Research: bought and took apart 3 best-selling models.
2. 2+ months of testing: analysed how the projectile, air hose and compressor fail.
3. 3 months of prototyping: built 5 functional prototypes for in-depth study.
4. 8+ months of iteration: repeated testing and adjustment.
5. Projectile material breakthrough: the right balance of hardness and toughness.
6. Aviation-grade air hose: custom supply with zero leakage.
7. Dual cooling: condenser plus fans, below 40°C.
8. Aging test: 5–8 million cycles per unit (simulating 3–5 years of use).
9. Samples approved: verified by the client, mass production order placed.
▎The result
After more than 8 months of development, 5 functional prototypes and up to 8 million test cycles, the client found no issues with the samples and placed a mass production order. This project marked our official entry into shockwave device manufacturing, a field we plan to keep investing in. The device has also been well received by other clients around the world.
