Drawer Guide Rail Clamping Mount for Secure Functional Parts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drawer pull-out guide rail systems face challenges in securely attaching functional parts, such as toothed racks, touch-latch devices, and damping devices, which can easily detach when force is applied, leading to unreliable operation.
Innovation Solution
A clamping device, comprising at least two bearing elements connected by a tensioning strap or form-fit fastening, secures the functional parts to the rail, preventing unintentional detachment and allowing for synchronized movement between separate drawer pull-out guides.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If functional parts are attached to the rail using end plugs or simple fastening methods, then the attachment process is quick and simple, but the functional parts can easily become detached when force is applied
Solution Approach 1:
The bearing elements are pre-positioned on the rail in a non-positive connection manner, allowing easy installation. Subsequently, the clamping device is activated to securely fasten the bearing elements to the rail, transforming the attachment from a simple preliminary state to a secure final state without requiring complex initial alignment
Solution Approach 2:
The clamping device transitions from an unactivated state where bearing elements are loosely positioned to an activated state where they are securely clamped to the rail. This dynamic transformation allows the system to adapt from an easy-to-install configuration to a force-resistant configuration based on operational requirements
2Reliability
If a secure attachment method is used to prevent detachment, then the attachment reliability improves, but the device complexity increases
Solution Approach 1:
The attachment system is divided into separate functional components: bearing elements that interface with the rail, a clamping device for securing, and a functional part interface. This segmentation allows each component to perform its specific function independently, maintaining reliability while avoiding the need for a monolithic complex attachment mechanism
Solution Approach 2:
The bearing elements serve multiple functions: they provide a mounting interface on the rail, serve as attachment points for the clamping device, and provide a connection interface for the functional part. This multi-functionality reduces the number of separate components needed, thereby reducing overall device complexity while maintaining secure attachment
