Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If light barriers are used to measure flight time, then measurement reliability is improved, but measurement precision deteriorates due to mat oscillations interrupting the beam path
Solution Approach 1:
The patent replaces the optical measurement system (light barriers) with a mechanical sensing system. Force sensors are integrated into the trampoline structure to directly measure the forces exerted by the athlete on the mat. This mechanical approach eliminates the problem of optical beam interruption by mat oscillations, as force sensors continuously detect contact forces regardless of mat position or vibration state.
2Adaptability or versatility
If light barriers are installed under the jumping mat, then flight time determination is enabled, but device complexity increases and functionality is limited
Solution Approach 1:
The force sensor system serves multiple functions simultaneously: it measures flight time by detecting when contact force drops to zero, determines jump height through force integration, analyzes landing position via sensor array spatial distribution, and monitors athlete performance parameters. This multi-functional approach eliminates the need for separate measurement systems while reducing overall device complexity.
Solution Approach 2:
The patent combines multiple measurement capabilities into a single integrated force sensing system. Instead of using separate light barriers for flight time, additional sensors for position tracking, and separate systems for height measurement, the force sensors directly provide all these measurements through unified signal processing of the contact force data.
3Ease of operation
If judges evaluate jumps subjectively, then evaluation flexibility is maintained, but measurement precision deteriorates
Solution Approach 1:
The system provides real-time feedback through automated processing of force sensor signals. The evaluation unit continuously monitors contact forces, automatically determines flight time parameters, and provides objective measurement data to judges. This maintains operational flexibility while eliminating subjective errors, as judges receive precise instrumental measurements that can be quickly referenced during evaluation.
