CPU Socket Cover Assembly Using a Buckled Elastic Sheet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During the reassembly of electronic devices, the independent loading mechanism's protective cover often interferes with the solder paste protective cover or heat dissipation elements, leading to a high probability of damage to CPU socket pins, necessitating replacement of the entire CPU socket.
Innovation Solution
An assembly method involving an elastic sheet with buckling portions is used to cover the CPU socket, preventing the solder paste protective cover from falling off and foreign objects from entering, by snapping the elastic sheet to the upper cover of the loading mechanism, ensuring protection of the CPU socket pins.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the upper cover is closed to protect the CPU socket, then the CPU socket is protected from foreign objects, but the solder paste protective cover cannot be properly assembled due to interference with the heat dissipation element
Solution Approach 1:
The protective cover assembly is segmented into multiple functional layers: the upper cover (112) forms the outer protective shell, the elastic sheet (120) creates a flexible sealing layer with buckling portions, and the solder paste protective cover (130) provides additional protection. This segmentation allows each layer to perform its specific function without interfering with assembly operations.
Solution Approach 2:
The elastic sheet (120) is pre-installed on the upper cover (112) before the solder paste protective cover (130) is assembled. The buckling portions are pre-formed to provide both sealing and operational clearance, eliminating the need for post-assembly adjustments and preventing interference during the assembly process.
2Object-affected harmful factors
If the solder paste protective cover is assembled to the loading mechanism, then the CPU socket gains protection, but the protective cover may fall off and damage the CPU socket pins
Solution Approach 1:
The elastic sheet (120) is a flexible thin film structure with buckling portions that conform to the contours of the upper cover (112). This flexible structure provides continuous contact and sealing along the perimeter, preventing the solder paste protective cover (130) from detaching while allowing for thermal expansion and manufacturing tolerances.
Solution Approach 2:
The buckling portions of the elastic sheet (120) provide dynamic adaptation to the assembly process. During assembly, the elastic sheet deforms to accommodate the solder paste protective cover (130), then returns to its original shape to maintain secure retention. This dynamic behavior ensures reliable protection without rigid constraints that could cause damage during assembly.
3Object-affected harmful factors
If the elastic sheet is designed to cover the CPU socket, then the socket is protected from foreign objects, but the assembly complexity increases due to the buckling portions
Solution Approach 1:
The elastic sheet (120) uses a thin film structure with integrated buckling portions that are formed as a single piece. This flexible membrane design provides effective sealing and protection while maintaining simplicity in manufacturing and assembly, avoiding the need for multiple rigid components fastened together.
Solution Approach 2:
The buckling portions of the elastic sheet (120) are self-aligning and self-retaining. During assembly, the elastic sheet automatically conforms to the upper cover (112) contours and secures itself through the buckling mechanism, eliminating the need for additional fasteners or complex alignment procedures. The structure serves its own installation and retention functions.

Function Achieved in This Case
The elastic sheet effectively prevents damage to CPU socket pins by securing the solder paste protective cover and heat dissipation elements, reducing the need for CPU socket replacement and ensuring smooth assembly and disassembly.

AI summary
The present disclosure provides an assembly method of an electronic device. The assembly method includes: opening an upper cover of a loading mechanism on a circuit board, in which the upper cover has an opening, and when the upper cover is in a closed state, the opening exposes a central processing unit socket located on the circuit board; snapping an elastic sheet to opposite sides of an inner edge of the opening of the upper cover through buckling portion of the elastic sheet; and closing the upper cover of the loading mechanism so that an elastic sheet body of the elastic sheet covers the central processing unit socket.
