Elastic Plate Holder Structure for Shock-Resistant Electronics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with plate-shaped members, such as antennas, suffer damage from shocks and vibrations due to stress concentration at screwed parts, leading to potential damage of the substrate.
Innovation Solution
An electronic device design featuring a base, case, electronic component, and a plate-shaped member with an elastic body sandwiched between the base and case, which holds the plate-shaped member without direct fixation, thereby reducing stress and potential damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the plate-shaped member is fixed to the base with screws, then the fixing strength is improved, but the plate-shaped member may be damaged by shock and vibrations due to stress concentration at screwed parts
Solution Approach 1:
The patent introduces an elastic body as an intermediary between the base and the plate-shaped member. This elastic body includes a holding portion that holds the plate-shaped member without direct screw fixation, thereby mediating the connection and distributing stress to prevent damage from shock and vibrations while maintaining fixing strength.
2Stability of the object's composition
If screws are used to fix the plate-shaped member, then the structural stability is improved, but the device complexity increases due to additional screwed parts
Solution Approach 1:
The patent merges the functions of fixation and cushioning into a single elastic body component. The elastic body simultaneously provides holding functionality and shock absorption, eliminating the need for separate screws and reducing device complexity while maintaining structural stability.
3Ease of manufacture
If direct screw fixation is used, then the manufacturing process is simplified, but waterproofness is compromised due to potential leakage paths at screwed joints
Solution Approach 1:
The elastic body acts as a flexible sealing element that conformally contacts the base and the plate-shaped member. This flexible structure creates effective sealing without requiring threaded joints, thereby maintaining waterproofness while simplifying the manufacturing process.
Applied Scientific Principles
