Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standardization elements are added to computer modules for interchangeability, then module interchangeability is improved, but internal space requirements increase
Solution Approach 1:
The patent combines the mounting screw and retention clip into a single integrated retention element. The retention element includes a body with a recess that receives the mounting screw, and a latch portion that engages with the module. This merging eliminates the need for separate mounting holes and multiple fastening components, reducing the space required in the motherboard while maintaining standardized interchangeability features.
Solution Approach 2:
The retention element serves multiple functions: it provides mechanical support for the module, secures the module through the latch mechanism, and enables standardized installation and removal. The mounting screw thread engages with threads in the retention element body, while the latch portion engages with the module, creating a universal retention solution that works with standardized modules across different configurations.
2Reliability
If mounting screws are used to secure computer modules, then module security is improved, but device complexity and installation time increase
Solution Approach 1:
The retention element is segmented into distinct functional portions: a body portion that receives the mounting screw, a latch portion that engages with the module, and an arm that provides leverage for installation. This segmentation allows each portion to be optimized for its specific function while being manufactured as a single integrated component, reducing overall complexity.
Solution Approach 2:
The retention element is designed to be self-aligning and self-securing. The latch portion automatically engages with the module when the retention element is installed, and the mounting screw threads self-align with the retention element body. This eliminates the need for complex alignment procedures or multiple adjustment steps, reducing installation time and complexity while maintaining secure module attachment.
3Reliability
If mounting screws and holes are used for module attachment, then module security is improved, but necessary installation space increases
Solution Approach 1:
The mounting screw is nested within the retention element body. The screw threads engage with internal threads formed in the retention element body, rather than requiring separate mounting holes in the motherboard. This nesting eliminates the need for additional holes through the motherboard, reducing the installation space and preserving motherboard real estate for other components.
4Ease of operation
If removable computer modules are implemented, then ease of replacement is improved, but space efficiency worsens
Solution Approach 1:
The retention element incorporates a dynamic latch mechanism that can be easily actuated to release the module. The latch portion engages with the module in a fixed position for secure operation, but can be easily disengaged by applying force to the retention element arm. This dynamic design enables easy module replacement while maintaining a compact structure that does not require additional space for complex release mechanisms.
