Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the mobile power source has a larger capacity, then the power supply capability is improved, but the structure becomes more complex
Solution Approach 1:
The mobile power source is divided into modular components including a battery assembly, housing with middle housing and covers, and a circuit board assembly. Each module can be independently assembled and disassembled, reducing overall structural complexity while maintaining large capacity functionality.
Solution Approach 2:
The battery assembly is nested within the housing, with the circuit board assembly positioned on top of the battery assembly. The middle housing contains the battery assembly, and the covers enclose the entire structure, creating a compact nested arrangement that optimizes space for large capacity batteries.
2Power
If the mobile power source has a complex structure, then the power supply capability is improved, but the assembly and disassembly operations become more complex
Solution Approach 1:
The device is segmented into clearly defined modules (housing, battery assembly, circuit board assembly, covers) that can be independently handled during assembly and disassembly operations, making maintenance and repair easier despite the overall complex functionality.
Solution Approach 2:
The pillars are pre-positioned on the middle housing to form support surfaces and limiting surfaces, creating predetermined positioning features that guide the assembly process and simplify subsequent assembly operations for other components.
3Power
If the mobile power source has a complex structure, then the power supply capability is improved, but the daily maintenance becomes more inconvenient
Solution Approach 1:
The modular structure allows the battery assembly and circuit board assembly to be independently accessed and replaced, facilitating easy maintenance and repair of specific components without disassembling the entire device, thus improving ease of repair despite complex functionality.
Solution Approach 2:
The battery assembly can be extracted from the housing as a complete module, allowing for easy replacement of the battery pack without disturbing other components, which simplifies maintenance operations for large capacity power sources.
4Ease of operation
If the mobile power source has a simple structure, then the assembly and disassembly operations are easier, but the stability of component placement may be compromised
Solution Approach 1:
The pillars are pre-installed on the middle housing to create fixed support surfaces and limiting surfaces before other components are assembled, establishing stable positioning features that ensure consistent and reliable component placement throughout the assembly process.
Solution Approach 2:
The support surface and limiting surface formed by the pillars act as intermediary elements between the housing and the battery assembly, providing stable mechanical connection and precise positioning without requiring complex fastening mechanisms.
