Drawer Pull-Out Guide Locking Actuator Mount for Flexible Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pull-out guides for drawers and furniture have limitations due to fixedly connected actuators, which complicate manufacturing, affect appearance and corrosion resistance, and restrict the ability to add actuators post-manufacturing.
Innovation Solution
The actuator is lockingly fixed to the running rail using a subassembly with a closing stopper, allowing for easy attachment at any time, eliminating the need for pre-matching running rails with or without actuators, and utilizing plastic components for precise fitting and reduced noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the actuator is fixedly connected to the running rail by welding, then the connection is strong and stable, but the appearance is degraded and corrosion resistance is reduced
Solution Approach 1:
The connection system is divided into separate components: the running rail, the actuator, and a locking mechanism. This segmentation allows the actuator to be attached without welding, preserving the running rail's appearance and corrosion resistance while maintaining a strong connection through the locking mechanism.
Solution Approach 2:
A locking mechanism serves as an intermediary between the actuator and the running rail, enabling a strong connection without direct welding. This intermediary component transfers and secures the connection forces while protecting the running rail from harmful welding effects.
2Ease of manufacture
If the actuator is pre-mounted on the running rail during manufacturing, then the assembly is complete, but the manufacturing complexity increases and flexibility is reduced
Solution Approach 1:
The actuator mounting is made dynamic and adjustable rather than fixed. The locking mechanism allows the actuator to be attached at different times and positions, enabling the system to adapt to different manufacturing scenarios and customer requirements without compromising assembly completeness.
Solution Approach 2:
The running rail is designed with universal mounting features that accommodate the actuator regardless of when or where it is attached. This universality allows the same running rail to be used in both pre-assembled and post-assembled configurations, eliminating the need for separate production lines.
3Adaptability or versatility
If the actuator is attached subsequently by the final customer, then the flexibility is improved, but the installation difficulty increases
Solution Approach 1:
The locking mechanism is divided into simple, separable components that can be easily assembled by the final customer. This segmentation reduces installation complexity while maintaining the flexibility for later attachment.
Solution Approach 2:
The locking mechanism is designed to be self-installing, allowing the final customer to attach the actuator without requiring specialized tools or expertise. The mechanism itself facilitates its own installation, reducing the perceived difficulty for end users.
