Power Module Bracketless Mounting via Integrated Protrusions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing power module installation methods require additional brackets, increasing installation costs, time, and occupying layout space, which are inefficient and wasteful.
Innovation Solution
A power module design without an additional bracket, featuring an outer shell with protrusion portions and fixing slots that allow direct installation onto an electronic device's inner surface using fastening elements, eliminating the need for L-shaped brackets and reducing assembly complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an L-shaped bracket is used to install the power supply, then the power supply can be securely fixed on the computer case, but the installation cost increases, installation time increases, and layout space is occupied
Solution Approach 1:
The patent merges the power supply housing with the mounting bracket function by integrating protrusion portions directly into the housing structure. The power supply housing itself serves dual purposes: containing internal components and providing mounting features (protrusion portions with fixing slots) for direct attachment to the computer case, thereby eliminating the need for a separate L-shaped bracket
Solution Approach 2:
The patent extracts the bracket function from the installation system and integrates it into the power supply housing structure. The mounting features (protrusion portions with fixing slots) are extracted from the separate bracket and built into the housing, allowing the housing to perform both containment and mounting functions simultaneously
2Reliability
If an L-shaped bracket is used to install the power supply, then the power supply can be securely fixed on the computer case, but the installation cost and installation time increase
Solution Approach 1:
The patent combines the power supply housing and mounting bracket into a single integrated structure. The housing includes built-in protrusion portions with fixing slots that directly engage with the computer case, eliminating the need for separate bracket assembly and reducing installation steps
Solution Approach 2:
The mounting features (protrusion portions with fixing slots) are pre-integrated into the housing structure during manufacturing. This preliminary integration of mounting capabilities eliminates the need for separate bracket assembly steps during installation, reducing installation time while maintaining secure fixation
3Reliability
If an L-shaped bracket is used to install the power supply, then the power supply can be securely fixed on the computer case, but the layout space is occupied
Solution Approach 1:
The patent merges the mounting function into the housing structure itself. The protrusion portions extend from the housing and provide fixing slots for direct attachment to the computer case, eliminating the need for an external L-shaped bracket that would occupy additional layout space

AI summary
A power module includes an outer shell, a circuit board, plural electronic components and a power transmission interface. The power transmission interface is electrically connected with the plural electronic components and partially exposed outside the outer shell. The outer shell includes a first lateral plate and a second lateral plate. The second lateral plate includes a first protrusion portion and a second protrusion portion. The first protrusion portion and the second protrusion portion are protruded relative to the first lateral plate and respectively located at two opposite edges of the second lateral plate. After fastening elements are respectively penetrated through a first fixing slot of the first protrusion portion and a second fixing slot of the second protrusion portion and tightened into a case of an electronic device, the power module is fixed and installed on an inner surface of the case.
