Adjustable Fixing Frame for Heat Sink on Varying Circuit Boards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional heat sink fixing frames require different sizes and shapes to accommodate various electronic components, leading to increased design and storage costs, which is not cost-effective or economical.
Innovation Solution
A fixing frame with a hollow area featuring a main accommodating space and one or more subsidiary spaces, along with a detachable foldable plate connected via connection ribs, allows for flexible assembly on circuit boards of varying sizes by adjusting the position of the foldable plate to accommodate different board lengths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different sizes and shapes of fixing frames are used to accommodate various electronic components, then the heat sink can be properly mounted to different components, but the design and storage costs increase
Solution Approach 1:
The fixing frame is designed with a hollow area containing a main accommodating space and at least one subsidiary accommodating space, allowing a single fixing frame design to accommodate electronic components of various sizes. The foldable plate can be adjusted or removed to adapt the frame to different component dimensions, eliminating the need for multiple specialized frame designs.
Solution Approach 2:
The accommodating space is divided into a main accommodating space and at least one subsidiary accommodating space separated by a foldable plate. This segmentation allows flexible configuration where the foldable plate can be positioned to create different compartment sizes, or removed entirely to create a larger single space, thereby adapting to various electronic component sizes with a single frame design.
2Adaptability or versatility
If different sizes and shapes of fixing frames are used to accommodate various electronic components, then the heat sink can be properly mounted to different components, but the storage costs increase
Solution Approach 1:
A single universal fixing frame design with adjustable foldable plates can serve multiple electronic component sizes, reducing the quantity of different frame variants that need to be manufactured and stored. The same frame can be configured differently by adjusting or removing foldable plates to fit various component dimensions.
3Ease of manufacture
If a fixed structure is used for the fixing frame, then the manufacturing process is simple, but the frame cannot adapt to various sized circuit boards
Solution Approach 1:
The fixing frame incorporates foldable plates that can be adjusted or removed based on the size of the circuit board being mounted. This dynamic element allows the frame to adapt its configuration while maintaining a relatively simple manufacturing process, as the basic frame structure remains the same and only the foldable plate configuration needs to be adjusted.

AI summary
A fixing frame for a heat sink includes boards, at least one foldable plate, and connection members. The boards surround a hollow area, and the hollow area includes a main accommodating space and at least one subsidiary accommodating space at one side of the main accommodating space. At least one foldable plate is detachably connected to one of the boards and is disposed in the subsidiary accommodating space. The connection members are disposed on the boards. By means of the connection members, the fixing frame mounts the heat sink on a circuit board of various sizes to dissipate heat therefrom.
