Computer Power Supply Housing With Hidden Screws for Smooth Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional computer power supplies have exposed locking screws, which affect aesthetics, cause user discomfort, and result in excessive friction and tremors during installation.
Innovation Solution
A power supply design that incorporates a base component, top cover component, and fan component, with hidden screw connections and a smooth, flat surface for improved installation quality and aesthetics by using fan and circuit board connectors that are concealed within the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If exposed locking screws are used to secure electronic elements, then the power supply structure is simple and easy to manufacture, but the aesthetics deteriorate and user comfort decreases
Solution Approach 1:
The patent extracts the locking screws from the visible exterior surface and relocates them to the interior structure. The top cover component is designed with integrated locking mechanisms that secure electronic elements from above, hiding all screws within the housing interior. This extraction principle resolves the contradiction by maintaining simple screw-based assembly while eliminating aesthetic and comfort issues caused by exposed screws.
Solution Approach 2:
The patent implements nesting by placing the locking mechanisms and screws within the nested structure of the housing components. The top cover component contains integrated locking features that nest over the side walls, with all fastening elements positioned within the nested layers of the housing rather than on the exterior surface. This nesting approach maintains manufacturing simplicity while achieving a clean exterior.
2Device complexity
If exposed locking screws are used to secure electronic elements, then the power supply structure is simple, but the flatness of the housing deteriorates causing excessive friction and tremors during installation
Solution Approach 1:
The patent extracts all protruding locking screws from the exterior surface and relocates them to the interior structure. The top cover component features integrated locking mechanisms that engage with the side walls from above, eliminating external protrusions. This extraction maintains relatively simple device structure while achieving the required flatness and precision for smooth installation without friction or tremors.
3Ease of manufacture
If locking screws are positioned on the exterior surface, then the assembly process is simple, but the aesthetic appearance deteriorates
Solution Approach 1:
The patent extracts all visible screws and locking elements from the exterior surface and relocates them to the interior structure. The top cover component is designed with integrated locking features that secure electronic elements from above, with all fastening operations performed within the housing interior. This achieves clean aesthetic appearance while maintaining simple assembly processes.
Solution Approach 2:
The patent implements nesting by positioning all locking mechanisms within the nested structure of the housing components. The top cover component contains integrated locking features that nest over the side walls, with all fastening elements positioned within the nested layers rather than on the exterior. This nesting approach achieves aesthetic appearance while maintaining ease of assembly.

AI summary
A power supply for a computer includes a base component, a top cover component and a fan component. The base component includes a bottom wall and two first direction side walls. The two first direction side walls are parallel to each other, and respectively connected to two ends of a first direction of the bottom wall. Each first direction side wall has two first extending portions, and the first extending portions extend along the first direction. The top cover component includes a top wall and two second direction side walls. The two second direction side walls are parallel to each other, and respectively connected to two ends of a second direction of the top wall, and respectively cover the first extending portions. The second direction is perpendicular to the first direction, and the first direction and the second direction are parallel to the bottom wall and the top wall.
