Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the voltage conversion function is integrated into the power supply control box, then power supply to devices with different operating voltages is achieved, but the arrangement of the voltage conversion function lacks optimization and the system becomes more complex
Solution Approach 1:
The power supply system is segmented into multiple independent circuit branches, each capable of receiving power from the power supply terminal. The voltage conversion function is separated as an independent module that can be selectively connected to specific branches, rather than being integrated into a single complex control box. This segmentation allows for optimized arrangement and reduces overall system complexity.
Solution Approach 2:
The voltage conversion module is designed with detachable connections to the circuit branches, allowing it to be dynamically connected or disconnected based on the specific power supply needs. This dynamic configuration enables flexible adaptation to different device voltage requirements without permanently increasing system complexity.
2Adaptability or versatility
If multiple circuit branches are provided for different power supply systems, then power distribution flexibility is improved, but the difficulty of adapting to device specification changes increases
Solution Approach 1:
The circuit is divided into multiple independent branches with standardized connection interfaces. Each branch can be independently configured and modified without affecting other branches, making it easier to adapt to device specification changes while maintaining power distribution flexibility.
Solution Approach 2:
The circuit branches are designed with universal connection standards and compatible interfaces, allowing the same branch structure to serve multiple different devices with varying voltage requirements. This universality simplifies manufacturing adaptations when device specifications change.
3Ease of repair
If the voltage converter is detachably provided from the power supply systems, then ease of repair and modification is improved, but connection reliability may be reduced
Solution Approach 1:
The detachable connection system employs dynamic connection mechanisms with built-in contact protection features. The connection interfaces are designed to maintain stable electrical contact during operation while allowing easy detachment when needed, thus achieving both ease of repair and connection reliability.
Solution Approach 2:
The connection interfaces incorporate protective measures such as contact protection structures and stable connection mechanisms that prevent degradation or failure before detachment is needed. This beforehand cushioning ensures reliable connections during operation while maintaining ease of modification.
