Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a boxing training device integrates electronic modules requiring electrical power, then the device can provide enhanced training feedback and control, but the device loses energy autonomy and requires external power sources
Solution Approach 1:
The device generates its own electrical energy through piezoelectric elements that convert mechanical energy from user strikes into electrical power, eliminating the need for external power sources and enabling true energy autonomy while supporting electronic modules
Solution Approach 2:
The piezoelectric elements change their electrical output parameters based on the mechanical stress applied during training, converting variable mechanical energy from punches into variable electrical energy to power electronic components
2Power
If the striking body is designed to oscillate freely to maximize energy generation, then electrical energy output increases, but the structural stability and control of the device decreases
Solution Approach 1:
The system uses elastic elements to enable controlled oscillation of the striking body, allowing dynamic movement that generates electrical energy while maintaining stable return to initial position through elastic recovery forces
Solution Approach 2:
The oscillation of the striking body is converted into electrical energy through piezoelectric elements, creating a feedback mechanism where the mechanical motion itself generates the power needed to control and stabilize the system

Implementation Method 2
at least one piezoelectric part disposed between the two annular plates
