Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional light-emitting devices use fixed light sequences and frequencies, then the device structure is simple, but the light display becomes monotonous and cannot adapt to user needs
Solution Approach 1:
The patent implements dynamic light sequences by using a controller that can change the emission order and frequency of light-emitting diodes based on different control signals. The system transitions from fixed patterns to dynamically adjustable sequences, allowing the light display to adapt to various user needs and environmental conditions while maintaining reasonable circuit complexity through programmable control.
2Illumination intensity
If light-emitting devices operate continuously, then the lighting effect is strong, but energy consumption increases
Solution Approach 1:
The patent employs periodic action by controlling light-emitting diodes to emit light in sequential patterns rather than continuously. The controller activates different LEDs at different time intervals according to predetermined sequences, creating strong illumination effects during active periods while consuming less energy during transition and idle periods. This periodic emission pattern maintains effective lighting intensity while significantly reducing overall energy consumption.
3Object-affected harmful factors
If light-emitting devices flash at high frequency, then the attention-catching effect is strong, but energy savings are reduced
Solution Approach 1:
The patent uses periodic action with variable frequencies to balance attention-catching effects and energy savings. The controller can adjust the flashing frequency of light-emitting diodes based on different operational modes, using higher frequencies when attention is needed and lower frequencies or longer intervals when energy conservation is prioritized. This creates an optimized balance between visual impact and energy efficiency.
Solution Approach 2:
The patent applies parameter changes by varying the flash frequency and duration of light-emitting diodes according to different operational requirements. The system can switch between different frequency parameters to achieve either strong attention-catching effects or energy-efficient operation, allowing flexible adjustment of the flash rate to match environmental conditions and user needs.
4Adaptability or versatility
If light-emitting devices use fixed emission patterns, then the circuit design is simple, but the device cannot meet different user needs or environmental conditions
Solution Approach 1:
The patent implements universality by designing a controller that can execute multiple light sequences and frequency patterns using a single circuit design. The controller responds to different control signals to produce various emission patterns, making the device adaptable to different user needs and environmental conditions without requiring multiple specialized circuits. This multi-functional approach enhances versatility while keeping the overall device complexity manageable.
