Drawer interlocking guide rail with locking function
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drawer guide rails with interlocking functions not only prevent multiple drawers from being pulled out simultaneously, thereby reducing the risk of cabinet tipping, but also produce a loud 'bang' sound when closing, which can disrupt sleep, especially in children's rooms.
Innovation Solution
A drawer interlocking guide rail with a locking function that incorporates multiple guide rail assemblies and an interlocking device. The interlocking device includes an interlocking base, slider, and rotating arm, along with a silencer locking stopper and tail clamping portion to prevent noise during closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a guide rail with self-locking function is used, then the drawer can be automatically closed, but a loud 'bang' sound is produced when the drawer closes
Solution Approach 1:
The patent introduces a silencer component as an intermediary element between the drawer and the guide rail. This silencer acts as a mediator that absorbs the impact energy during drawer closure, preventing the direct collision that causes the loud bang sound, while still allowing the automatic closure function to operate effectively.
Solution Approach 2:
The patent incorporates cushioning elements in advance within the guide rail structure. These cushioning components are pre-positioned to absorb impact energy before the drawer fully closes, eliminating the harmful noise while maintaining the automatic closure capability. The cushioning is built into the design from the outset rather than added as an afterthought.
2Ease of operation
If multiple drawers are allowed to be pulled out simultaneously, then ease of access is improved, but the cabinet risks tipping over
Solution Approach 1:
The patent implements a dynamic interlocking mechanism that automatically adjusts the locking state of multiple drawers based on their positions. When one drawer is pulled out, the interlocking device dynamically changes the state of other drawers, preventing them from being pulled out simultaneously. This dynamic control maintains cabinet stability while still allowing convenient access to drawers when needed.
3Stability of the object's composition
If an interlocking device is added to prevent multiple drawers from being pulled out, then cabinet stability is improved, but the device complexity increases
Solution Approach 1:
The patent merges the interlocking function with the existing guide rail structure. Instead of adding a completely separate interlocking mechanism, the invention integrates the locking and unlocking functions into the guide rail components themselves. The interlocking device is combined with the silencer and existing rail elements, reducing overall structural complexity while maintaining the stability function.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents multiple drawers from being pulled out at once, thereby preventing cabinet overturning, while also eliminating the loud noise associated with drawer closure, thus enhancing sleep quality, especially in children's environments.
Implementation Method 1
the end of the outer rail is provided with a silencer locking stopper for matching and clamping with the tail clamping portion
Implementation Method 2
When the drawer is automatically closed under the action of the spring
