Extension Board Support Structure for Vibration Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing devices face challenges in preventing displacement and deformation of extension boards due to vibration or shock, especially in compact designs where the space between components is limited, leading to potential contact with nearby components and performance issues.
Innovation Solution
The solution involves a supporting member fixed to the housing, parallel to the substrate, which supports the extension board using a holding member that is movable and adjustable to accommodate various shapes and sizes, with an elongated hole and through-holes for secure fixation, preventing displacement and deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the extension board is fixed by screwing at one position of a non-engagement portion of a connector, then the extension board can be mounted, but the extension board may be deformed by vibration or shock and is liable to be displaced
Solution Approach 1:
The fixing structure is divided into multiple independent fixing portions (first fixing portion and second fixing portion) that are separated from each other. Each fixing portion independently secures the extension board at different locations, distributing the mechanical stress and preventing displacement while maintaining mounting simplicity
Solution Approach 2:
Different regions of the extension board are provided with different fixing characteristics. The first fixing portion and second fixing portion are located at different positions (front side and rear side respectively) and provide localized support tailored to the specific mechanical requirements of each region, enhancing overall fixation stability
2Volume of moving object
If the size of the device is reduced to occupy less space, then the device becomes more compact, but the extension board may touch components nearby during vibration or shock
Solution Approach 1:
The extension board is pre-restricted in its movement range by the first fixing portion and second fixing portion before any harmful contact can occur. These fixing portions create preliminary mechanical constraints that prevent the extension board from moving enough to touch nearby components, even during vibration or shock in compact device configurations
3Adaptability or versatility
If various kinds of fixing members are used to fix various kinds of extension boards, then different shapes and sizes can be accommodated, but the device complexity increases
Solution Approach 1:
The first fixing portion and second fixing portion are designed with universal functionality to accommodate extension boards of various shapes and sizes. Rather than using different fixing members for different board types, the same dual-fixing structure serves multiple purposes through strategic positioning and geometric design, reducing device complexity while maintaining adaptability

AI summary
An information processing device is disclosed that is able to prevent displacement of an extension board caused by vibration or shock, and able to prevent deformation of the extension board and members nearby. The information processing device includes a substrate with a CPU (Central Processing Unit) mounted thereon, a housing that accommodates the substrate, an extension board arranged to be parallel to the substrate, and a supporting member that is fixed on the housing and is arranged to be parallel to at least one end surface of the substrate so that the supporting member supports the extension board.
