Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing striking gloves with fluid-filled bodies and pressure sensors often deliver implausible readings during actual combat sports due to uneven force distribution causing the fluid-filled body to compress excessively, leading to inaccurate pressure measurements.
Innovation Solution
A striking glove design with a damping element between the impact surface and fluid-filled body, ensuring the opposite sides of the fluid-filled body remain in contact during strikes on a 7 cm cylinder, using a high damping coefficient, low expansion coefficient, and additional support structures to prevent excessive compression, combined with a high-acceleration sensor for accurate force measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the fluid-filled body is made compressible to measure impact force, then force measurement capability is improved, but the opposite sides may touch during impact causing implausible readings
Solution Approach 1:
A damping body is placed between the impact surface and the fluid-filled body to absorb and distribute impact forces before they reach the fluid-filled body. This pre-cushioning prevents the opposite sides of the fluid-filled body from touching during impact, ensuring reliable pressure measurements while maintaining force measurement capability.
Solution Approach 2:
The damping body acts as an intermediary element between the external impact and the fluid-filled body. It mediates the force transmission by distributing the impact load, preventing direct compression that would cause the opposite sides of the fluid-filled body to touch, thus maintaining measurement reliability.
2Reliability
If the damping coefficient is increased to prevent fluid body contact, then measurement reliability is improved, but impact force transmission to the sensor is reduced
Solution Approach 1:
The damping coefficient is optimized to a specific range that balances two requirements: it is high enough to distribute impact forces and prevent the opposite sides of the fluid-filled body from touching, but not so high that it prevents effective force transmission to the pressure sensor. This parameter optimization ensures both measurement reliability and accurate force measurement.
3Reliability
If the fluid-filled body is made more resistant to compression, then contact between opposite sides is prevented, but the sensitivity to impact force decreases
Solution Approach 1:
The damping body provides beforehand cushioning that prevents the fluid-filled body from experiencing extreme compression that would cause contact between opposite sides. This allows the fluid-filled body to maintain its sensitivity to impact forces while ensuring that compression remains within a range that prevents contact, thus maintaining both reliability and measurement precision.

Implementation Method 1
When a hit is landed on an opponent with these punching gloves, the fluid body is compressed or pressurized. According to Boyle's law, when an air-filled body is compressed, the internal pressure increases inversely proportional to the volume.
Implementation Method 2
a pressure sensor (3) for measuring the hydrostatic pressure in the fluid-filled body (2)
