Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors and electronic devices are added to punching pads to detect and provide feedback, then measurement precision and interactivity are improved, but device complexity increases
Solution Approach 1:
The patent combines multiple sensors (force sensors, accelerometers, gyroscopes) and electronic components (LEDs, controllers) into an integrated punching pad assembly. The sensors are embedded within the pad structure itself, merging detection, feedback, and structural functions into a single unified device, thereby improving measurement precision while managing system complexity through integration.
Solution Approach 2:
The punching pad is designed to perform multiple functions simultaneously: it serves as a structural target for punching, a sensing device for detecting strike parameters (force, acceleration, orientation), and a feedback device through visual (LED) and audio outputs. This multi-functionality allows the same device to improve measurement precision while providing comprehensive training feedback without requiring separate dedicated components for each function.
2Adaptability or versatility
If multiple sensors and electronic components are integrated into the punching pad, then functionality and feedback capability are improved, but ease of manufacture deteriorates
Solution Approach 1:
The punching pad is constructed as a layered assembly with distinct components (backing layer, sensor housing, flexible PCB, foam layer, front layer) that can be manufactured separately and then assembled. This segmentation allows each component to be optimized and manufactured independently using appropriate processes, then combined through standardized interfaces, thereby improving adaptability while managing manufacturing complexity through modular construction.
Solution Approach 2:
The patent employs a nested structure where sensors are housed within protective housings that are integrated into the pad layers. The flexible PCB is embedded within the foam layer, and electronic components are nested within the multi-layer construction. This nesting approach allows complex functionality to be achieved while maintaining a compact form factor and simplifying assembly by pre-integrating components during manufacturing of each layer.
3Productivity
If real-time feedback and gamification features are implemented, then user engagement is improved, but use of energy increases
Solution Approach 1:
The feedback system operates periodically rather than continuously - LEDs are activated in response to detected strikes, and audio feedback is provided at discrete moments when punching events occur. The controller enters low-power states between detection events, and sensors are activated only when needed. This periodic operation maintains high user engagement through timely feedback while significantly reducing average power consumption compared to continuous operation.
Solution Approach 2:
The system provides immediate visual and audio feedback when a strike is detected, creating an engaging interactive experience. The feedback is event-triggered rather than continuous, with LEDs illuminating and audio cues playing only in response to actual punching events. This feedback mechanism maintains high user engagement and motivation while consuming energy only when necessary, rather than operating continuously.
