Bracket With Elastic Member For Stable Electronic Device Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brackets for fixing electronic devices to enclosures are prone to bending under excessive torque and can cause scratches or stress concentration on the enclosure surface, leading to unstable fixing and potential damage.
Innovation Solution
A bracket with an L-shaped body and a tapered connection, featuring a coupling member that presses the front and rear faces of the enclosure together, along with an elastic member to enhance contact and absorb impacts, and a guide system to prevent deviation, ensuring a stable fixing force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional bracket is used to fix the electronic device, then the device can be mounted to the enclosure, but the bracket may bend when excessive torque is applied, leading to unstable fixing
Solution Approach 1:
The bracket is divided into multiple portions (first portion, second portion, third portion) with different functions. The first portion provides structural support, the second portion engages with the electronic device, and the third portion interfaces with the enclosure. This segmentation allows each portion to be optimized for its specific function, preventing overall bracket bending while maintaining fixing stability.
Solution Approach 2:
The bracket incorporates an elastic member made of rubber or similar material between the third portion and the enclosure surface. This composite material approach combines the rigidity of the bracket body with the flexibility and stress-distributing properties of the elastic material, preventing bracket bending while protecting the enclosure surface.
2Reliability
If the screw bolt is screwed directly into the bracket, then the electronic device can be fixed, but scratches may be generated on the enclosure surface or stress may be concentrated on the small contact area
Solution Approach 1:
An elastic member is introduced as an intermediary between the bracket's third portion and the enclosure surface. This elastic member acts as a mediator that distributes the contact stress over a larger area, preventing scratches on the enclosure surface while maintaining secure fixing. The elastic material deforms to accommodate surface irregularities and distributes loads evenly.
3Ease of manufacture
If the bracket structure is simplified, then manufacturing is easier, but the bracket cannot provide sufficient fixing force
Solution Approach 1:
The bracket is segmented into three functional portions, each optimized for its specific role. This segmentation allows for efficient manufacturing of each portion while the overall structure provides sufficient fixing force through the coordinated action of all portions. The first portion provides structural integrity, the second ensures device engagement, and the third delivers mounting force.
Solution Approach 2:
By combining the rigid bracket body with an elastic member, the structure achieves both ease of manufacture (through standardized components) and sufficient fixing force (through the composite action of rigid and elastic materials working together).
