Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If battery cells are used to power the inner red-dot sighting device, then the device can operate continuously, but the cells have limited lifetimes and require frequent replacement, increasing cost
Solution Approach 1:
The power supply system is segmented into two independent parts: a solar cell for primary power generation and a battery cell for supplementary power. This segmentation allows the solar cell to handle daytime operation while the battery cell only needs to provide power during nighttime or low-light conditions, significantly extending the effective operational lifetime of the battery cell from daily replacement to monthly or yearly replacement.
Solution Approach 2:
The solar cell is designed to serve multiple functions: it acts as the primary power source during daytime, automatically charges the battery cell when light is available, and the system can switch between power sources based on environmental conditions. This multi-functionality reduces reliance on battery cells alone and extends their effective service life.
2Power
If battery cells are used to power the LED light source, then the device can maintain stable power supply, but the cells should be replaced frequently, increasing using cost
Solution Approach 1:
The solar cell and battery cell are merged into a hybrid power supply system where both sources work together. The solar cell panel, charging circuit, and battery cell are integrated with automatic switching control, creating a unified power system that combines the advantages of both power sources: the renewable energy from solar cells and the stable stored energy from battery cells.
Solution Approach 2:
The system incorporates automatic detection and switching functionality that monitors light conditions and power availability without user intervention. The control circuit automatically determines when to use solar power, when to charge the battery, and when to switch to battery power, making the system self-managing and reducing maintenance requirements.
3Illumination intensity
If the luminance of the light emitted from the inner red-dot module is adjusted based on environment luminance, then the visibility is optimized, but the current or voltage supplied by the cell should be adjusted, requiring complex control
Solution Approach 1:
The system incorporates an environment light sensor that continuously monitors ambient luminance levels and provides feedback to the control circuit. Based on this feedback, the control circuit automatically adjusts the driving current to the LED light source, optimizing visibility in different lighting conditions without requiring manual intervention or complex user interfaces.
Solution Approach 2:
The manual mechanical adjustment of luminance (through physical switches or dials) is replaced with an automatic electronic control system that uses light sensors and microcontrollers to dynamically adjust the LED current. This substitution of mechanical adjustment with automated electronic control simplifies the user interface while maintaining precise luminance optimization.
