Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wireless control device structure is used, then control functionality is achieved, but device complexity increases and costs increase
Solution Approach 1:
The wireless receiving circuit is divided into four distinct functional modules: signal receiving module (with Bluetooth antenna and capacitors), Bluetooth signal processing module (with processing chip and crystal oscillation unit), voltage stabilization module (with voltage stabilization chip and capacitors), and output control module (with switch control component and resistors). This segmentation allows each module to be optimized independently while maintaining overall system reliability and simplifying the overall structure through modular design.
Solution Approach 2:
The Bluetooth signal processing module serves multiple functions: receiving Bluetooth signals, processing control commands, providing clock signals through the crystal oscillation unit, and interfacing with both the signal receiving module and output control module. This multi-functionality reduces the need for separate dedicated components, thereby reducing device complexity while maintaining signal transmission stability.
2Reliability
If traditional wireless control device structure is used, then control functionality is achieved, but costs increase
Solution Approach 1:
Multiple functions are merged into integrated circuits: the Bluetooth signal processing chip handles signal reception and processing, the voltage stabilization chip provides voltage regulation, and the crystal oscillation unit provides clock signals. This merging reduces the number of discrete components needed, simplifying manufacturing and reducing costs while maintaining reliable signal transmission.
Solution Approach 2:
The voltage stabilization module automatically regulates voltage to the Bluetooth signal processing module without external intervention, and the crystal oscillation unit self-generates clock signals. These self-service functions eliminate the need for additional control circuits or manual adjustments, reducing manufacturing complexity and cost while ensuring stable operation.
3Reliability
If voltage stabilization processing is applied to Bluetooth signal processing module, then signal transmission stability improves, but device complexity increases
Solution Approach 1:
The voltage stabilization module acts as an intermediary between the power supply and the Bluetooth signal processing module. It receives unstable voltage from the power supply, stabilizes it through the voltage stabilization chip and capacitors, and provides clean, stable voltage to the Bluetooth signal processing module. This intermediary function ensures signal transmission stability without requiring complex voltage regulation circuits within the Bluetooth module itself.
