System having a bracket for a shelf of a rack
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shelving systems with electrical supply consoles cannot ensure stable electrically conductive connections between the console and the shelf post when the console is attached at different inclined positions, as the known solutions only guarantee contact at a predetermined position or inclination.
Innovation Solution
The console design includes a base body and a contacting element that can be pivoted relative to each other, allowing the console to be attached to the shelf post in multiple inclined positions, with the contacting element inserting into hanging openings to establish an electrically conductive connection with the shelf post's electrical conductor, ensuring contact in any intended inclination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the console is designed with a fixed predetermined inclination, then stable electrically conductive connection is guaranteed, but the console cannot be attached at different inclined positions
Solution Approach 1:
The contacting element is designed to be movable relative to the base body, allowing it to dynamically adjust its position and maintain electrical contact with the shelf post regardless of the console's inclination angle. This dynamic mechanism resolves the contradiction by enabling both stable connection and adaptability to different positions.
Solution Approach 2:
The console is divided into separate functional components: a base body for mechanical attachment and a contacting element for electrical connection. This segmentation allows the contacting element to independently adjust its position relative to the base body, maintaining reliable electrical contact while the base body remains attached at various inclined positions.
2Adaptability or versatility
If the console is designed to be pivotable for different inclined positions, then adaptability is improved, but stable electrically conductive connection cannot be guaranteed
Solution Approach 1:
The contacting element incorporates a dynamic adjustment mechanism that automatically compensates for changes in inclination angle. As the base body pivots to different positions, the contacting element moves accordingly to maintain continuous electrical contact with the shelf post, ensuring reliability across all inclined positions.
Solution Approach 2:
The contacting element is designed to self-adjust its position in response to changes in the console's inclination. Through elastic deformation or mechanical movement, it automatically maintains contact with the shelf post without requiring external adjustment mechanisms, ensuring stable electrical connection regardless of the base body's orientation.
3Ease of manufacture
If a rigid contacting element is used, then manufacturing precision is easier to achieve, but the contacting element cannot adapt to position changes
Solution Approach 1:
The contacting element is designed with elastic properties that allow it to change its physical state between rigid and flexible. This enables the element to maintain a simple, manufacturable base structure while acquiring the ability to adapt its position through elastic deformation when needed, resolving the contradiction between ease of manufacture and adaptability.
