Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If all light emission units are activated to disorientate personnel within active range, then the disorientation effect is maximized, but power consumption increases significantly
Solution Approach 1:
The patent applies local quality by activating only specific light emission units in specific regions where targets are detected, rather than uniformly activating all units. The sensor units detect targets in specific regions, and the processor selectively activates only the light emission units corresponding to those regions, creating localized disorientation effects where needed while conserving power in regions without targets.
Solution Approach 2:
The device divides the operational environment into multiple discrete regions, each with its own light emission units and sensor coverage. This segmentation allows independent control of each region's light emission based on local target detection, enabling the system to activate only the necessary segments (regions with targets) rather than the entire system, thus reducing overall power consumption while maintaining effective disorientation where required.
2Ease of operation
If non-pyrotechnic light emission units are used to disorientate personnel, then the device can be selectively activated, but the devices are indiscriminate and disorientate all personnel within range including friendly personnel
Solution Approach 1:
The patent implements local quality by assigning different operational characteristics to different light emission units based on their spatial location and detected target types. The sensor units identify whether detected targets are friendly or hostile, and the processor applies different activation patterns - activating only hostile targets with disorientating light while leaving friendly personnel unaffected. This creates localized disorientation effects specifically targeted at hostile individuals while preserving safety for friendly personnel in the same environment.
3Area of stationary object
If multiple light emission units are activated simultaneously to cover all regions, then complete area coverage is achieved, but the device complexity and power demand increase
Solution Approach 1:
The patent applies dynamics by making the light emission unit activation state changeable and adaptive based on real-time sensor feedback. The processor dynamically determines which light emission units to activate in each region based on current target detection data, allowing the system to expand coverage to all regions when threats are present while reducing activation to minimal necessary regions when threats are absent, thus managing both coverage and complexity adaptively.
