Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the circuit board size or lock hole positions are changed, then the circuit module can be modified, but a new metal shield is needed, increasing manufacturing costs
Solution Approach 1:
The metal shield is designed with a universal structure that can accommodate different circuit board sizes and lock hole positions through the engaging element mechanism. The engaging element acts as an intermediary that adapts to various circuit board configurations without requiring changes to the metal shield itself, thus maintaining manufacturing economy while enabling circuit module modifiability.
Solution Approach 2:
The engaging element serves as an intermediary component between the circuit board and the metal shield. It includes a retaining body with positioning structures that can engage with different lock hole positions on various circuit boards, and a conductive element that provides electrical connection. This intermediary mechanism allows the same metal shield to work with different circuit board designs.
2Device complexity
If the circuit board is fastened directly to the housing, then the assembly structure is simplified, but the housing complexity increases and assembly difficulty increases
Solution Approach 1:
The fastening system is segmented into three independent components: the metal shield, the engaging element, and the housing. The engaging element is a separate component that interfaces between the circuit board and the metal shield, rather than directly fastening the circuit board to the housing. This segmentation allows each component to be optimized independently and simplifies the assembly process.
Solution Approach 2:
The engaging element acts as an intermediary component that facilitates the connection between the circuit board and the metal shield. It includes a retaining body for mechanical retention and a conductive element for electrical connection, separating these functions from the housing structure and reducing housing complexity.
