Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an external power supply module is detachably connected to allow flexible power switching, then adaptability is improved, but connection reliability deteriorates
Solution Approach 1:
The power supply system is divided into separate modules: a removable external power supply module and an internal battery module. This segmentation allows flexible switching between power sources while maintaining reliable connections through standardized connector interfaces on the circuit board module.
Solution Approach 2:
The connector connection portion on the circuit board module is designed to universally accept both the external power supply module and the battery module. This multi-functional connector design enables the system to adapt to different power sources without requiring separate connection mechanisms, thereby maintaining both flexibility and reliability.
2Adaptability or versatility
If a storage space for batteries is formed in the case, then adaptability is improved, but device complexity increases
Solution Approach 1:
The storage space for the battery module is integrated into the existing case structure of the wireless terminal device. By merging the battery storage function with the housing design, the system provides multiple power supply options without adding separate structural components, thereby avoiding increased device complexity.
3Ease of operation
If the connector connection portion is provided at a position spatially connected to the storage space, then ease of operation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The connector connection portion is pre-positioned on the circuit board module at a location that aligns with the storage space in the case. This preliminary positioning ensures that when the battery module is installed in the storage space, the connectors automatically align and connect without requiring complex adjustment mechanisms, thereby facilitating easy operation while managing manufacturing precision requirements.
