Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional LED lamp strip controllers are used, then the device structure is simple and easy to manufacture, but the controller cannot sense environmental changes and lacks flexibility in controlling lighting modes
Solution Approach 1:
The patent combines multiple control functions (infrared control, audio control, and point control) into a single integrated controller unit. The controller includes an infrared receiving circuit, audio receiving circuit, control circuit, and drive circuit all in one device, allowing it to sense environmental changes through multiple modalities and provide flexible lighting mode control without requiring separate control devices for each function.
Solution Approach 2:
The controller is designed with multi-functional capabilities to perform diverse control tasks. It can receive infrared signals for remote control, detect audio signals for sound-responsive lighting, and respond to point control inputs. This universal design enables a single device to handle multiple control scenarios, improving adaptability while maintaining a unified structure.
2Adaptability or versatility
If multiple control circuits (infrared, audio, point control) are integrated into one controller, then environmental sensing capability and control flexibility are improved, but the device complexity increases
Solution Approach 1:
The controller is divided into distinct functional modules: an infrared receiving circuit for infrared signal detection, an audio receiving circuit for sound signal detection, a control circuit for processing signals and generating control outputs, and a drive circuit for driving the lamp strip. This segmentation allows each module to perform its specific function independently while being integrated into a unified controller, managing complexity through modular design.
Solution Approach 2:
The control circuit acts as an intermediary between the signal receiving circuits (infrared and audio) and the drive circuit. It processes the received signals, generates appropriate control signals, and coordinates the operation of different modules. This intermediary function simplifies the integration complexity by providing a central processing point that manages the interaction between multiple circuits.
3Area of stationary object
If the infrared transmitting circuit continuously transmits infrared signals to form a sensing area, then the sensing coverage is improved, but the energy consumption increases
Solution Approach 1:
Instead of continuous transmission, the infrared transmitting circuit operates periodically or intermittently. The controller transmits infrared signals at specific intervals or when triggered by detected events, rather than maintaining continuous transmission. This periodic operation maintains sensing coverage capability while significantly reducing the energy consumption of the infrared transmitting circuit.
