Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed force value curve is used for the trigger, then the device structure is simple, but the user experience cannot be adjusted for different game scenarios
Solution Approach 1:
The patent implements dynamic force feedback by using a coil and magnetic circuit system that can generate variable electromagnetic forces. The force value curve is no longer fixed but can be dynamically adjusted by changing current parameters, allowing the trigger to provide different resistance characteristics for different game scenarios while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent changes the electrical parameters (current magnitude, pulse width, frequency) of the coil to achieve different force feedback effects. By controlling the current parameters, the system can generate different force value curves without mechanical reconfiguration, thus improving adaptability while keeping the device structure simple.
2Ease of operation
If electromagnetic induction force is used for force feedback, then the force can be dynamically adjusted, but the device complexity increases due to additional components
Solution Approach 1:
The patent replaces traditional mechanical force feedback mechanisms with an electromagnetic system. Instead of using complex mechanical linkages, springs, and dampers to control trigger resistance, the system uses a coil and magnetic circuit to generate electromagnetic forces that directly act on the trigger, simplifying the mechanical structure while enabling precise electronic control.
Solution Approach 2:
The electromagnetic system serves multiple functions: it provides the primary force feedback, enables dynamic adjustment of force characteristics, and can be controlled through software to achieve different game scenarios. This multi-functionality reduces the need for separate mechanical components for each function.
3Ease of manufacture
If a torsion spring is used as reset member, then the trigger return mechanism is simple, but the force feedback precision may be affected
Solution Approach 1:
The patent merges the reset function and force feedback function into a single integrated system. The torsion spring provides the reset force while the electromagnetic system provides the force feedback. By coordinating these two systems through electronic control, the patent achieves both mechanical simplicity and force feedback precision.
