Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing control solutions are used, then the control system is simple, but the flexibility and adaptability to various commercial vehicle states are insufficient
Solution Approach 1:
The control device is designed with multi-functionality to handle various commercial vehicle states (door openings, load weights, battery states) through a single integrated system. The control means can execute different lighting functions (permanent, flashing, color, dimming) based on received sensor signals, making the system universally applicable to multiple vehicle conditions without requiring separate control systems for each state.
Solution Approach 2:
The control device incorporates dynamic adaptability through programmable configuration that can be modified via wireless communication. The control means can dynamically adjust lighting functions based on real-time sensor inputs and configurable parameters, allowing the system to adapt its behavior to different operational conditions without physical reconfiguration.
2Adaptability or versatility
If multiple lighting functions are implemented, then the functionality is enhanced, but the energy consumption increases
Solution Approach 1:
The control device implements periodic action through flashing lighting functions that can be configured to operate intermittently rather than continuously. This allows the system to provide necessary lighting information while reducing overall energy consumption compared to permanent illumination, particularly for indicator and warning functions where continuous light is not required.
Solution Approach 2:
The system dynamically adjusts lighting output based on battery state of charge levels. When battery charge is low, the control means can automatically reduce lighting intensity or deactivate non-essential lighting functions to conserve energy, while still maintaining essential lighting operations. This dynamic energy management allows versatile lighting functionality while adapting power consumption to available energy reserves.
3Productivity
If sensor-based automatic control is implemented, then the responsiveness to vehicle states is improved, but the device complexity increases
Solution Approach 1:
The control device processes sensor information in a segmented manner, with the control means evaluating sensor signals against configurable criteria to determine appropriate lighting responses. This segmentation of the control process allows the system to handle multiple sensor inputs (door sensors, load sensors, battery sensors) through a structured decision-making framework, improving response efficiency while managing complexity through organized signal processing.
Solution Approach 2:
The system implements feedback mechanisms where sensor signals about vehicle states (door openings, load weights, battery levels) continuously inform the control means, which adjusts lighting functions accordingly. This feedback loop enables automatic responsive control without requiring complex manual intervention, as the system self-regulates based on real-time vehicle condition monitoring and configurable response parameters.
