Drawer Slide Bearing Carrier Hook Positioning and Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drawer slide positioning systems face issues with the bearing carrier's vulnerability to displacement and outdated releasing mechanisms, leading to insecure positioning and potential damage.
Innovation Solution
A positioning device for a drawer slide bearing carrier featuring a recess with a hook portion, a pivotally connected hook unit, and an elastic force to restore its original position, along with a releasing mechanism that controls the hook unit's movement and engagement with a restrictor to secure and disengage the bearing carrier.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a temporary elasticity retaining function is used to locate the bearing carrier, then the device complexity is reduced, but the reliability of positioning deteriorates causing vulnerability to displacement
Solution Approach 1:
The hook unit is designed to be movable rather than fixed, allowing it to dynamically adapt between engagement and disengagement states. The elastic component enables the hook unit to flexibly respond to forces applied during drawer operation, providing reliable positioning when engaged while allowing controlled release when needed, thus resolving the contradiction between simple temporary retention and secure reliable positioning.
2Reliability
If an enforcing locating function is provided to secure the bearing carrier, then the reliability of positioning is improved, but the device complexity increases due to outdated releasing mechanisms
Solution Approach 1:
The releasing function is merged with the existing elastic component and hook unit structure. The elastic component serves dual purposes: providing the enforcing locating force to secure the bearing carrier reliably, and simultaneously enabling the releasing mechanism through its inherent elasticity. This integration eliminates the need for separate complex releasing mechanisms while maintaining reliable positioning.
Solution Approach 2:
The elastic component automatically provides both the positioning force and the releasing capability without requiring external control mechanisms. When force is applied to the drawer, the elastic component self-adjusts to release the hook unit, enabling the bearing carrier to be repositioned. This self-service mechanism simplifies the overall device complexity while maintaining reliable enforcing locating function.
3Reliability
If the bearing carrier is securely positioned to prevent displacement, then the reliability is improved, but the ease of operation deteriorates due to difficulty in releasing
Solution Approach 1:
The elastic component creates a dynamic positioning system that is secure during normal operation but easily releasable when force is applied. The hook unit remains firmly engaged under normal conditions, providing reliable positioning security. However, when the drawer is pulled or pushed, the elastic component flexes and automatically releases the hook unit, making the operation easy without requiring additional mechanisms or excessive force.

AI summary
A positioning device for a drawer slide bearing carrier includes a bearing carrier having rollers located between a carrying rail and a sliding rail. The bearing carrier has a recess and a hook portion at a front end thereof. The carrying rail has a support at a front end thereof. The support comprises a hook unit which is pivotally connected to a block fixed on the carrying rail. An elastic force is formed between the support and the hook unit, urging the hook unit to restore its original position. Thereby, the front end of the bearing carrier is pressed by the block so that the hook portion engages with the hook unit to secure the bearing carrier in place. The carrying rail further comprises a releasing mechanism adapted to control the swing of the hook unit for the movement of different locations.
