Computer Power Supply Concealed Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional computer power supplies have exposed fastening screws that disrupt the evenness of the outer case, cause friction issues during installation, and are aesthetically unpleasing due to visibility, potentially discomforting for individuals with trypophobia.
Innovation Solution
A computer power supply design featuring a base, fan assembly, internal part assembly, and cover with internalized fastening structures, eliminating exposed screws and ensuring a smooth, even outer surface for seamless installation and aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional fastening screws are used to secure the power supply components, then the structural stability is improved, but the outer surface evenness deteriorates due to exposed screws
Solution Approach 1:
The fastening screws are nested within recessed fastening sections on the base and corresponding recessed areas on the cover. The screws are completely enclosed within the power supply case, with their heads positioned below the outer surface of the base and cover, achieving both secure fastening and a smooth external appearance.
2Ease of manufacture
If exposed fastening screws are used, then the ease of assembly is improved, but the friction during installation worsens due to irregular surfaces
Solution Approach 1:
The fastening screws are nested within recessed fastening sections on the base and corresponding recessed areas on the cover. The screws are completely enclosed within the power supply case, with their heads positioned below the outer surface of the base and cover, achieving both secure fastening and a smooth external appearance.
3Reliability
If multiple fastening screws are exposed, then the reliability of fastening is improved, but the aesthetic appearance worsens due to visibility through transparent cases
Solution Approach 1:
The fastening screws are nested within recessed fastening sections on the base and corresponding recessed areas on the cover. The screws are completely enclosed within the power supply case, with their heads positioned below the outer surface of the base and cover, achieving both secure fastening and a smooth external appearance.
4Strength
If exposed fastening elements are used, then the structural integrity is improved, but the psychological comfort worsens for individuals with trypophobia
Solution Approach 1:
The fastening screws are nested within recessed fastening sections on the base and corresponding recessed areas on the cover. The screws are completely enclosed within the power supply case, with their heads positioned below the outer surface of the base and cover, achieving both secure fastening and a smooth external appearance.
