Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current furniture systems lack a reliable mechanism for synchronously moving two slide rail assemblies, which affects the stability and efficiency of drawer opening and retraction processes.
Innovation Solution
A synchronization system comprising a first and second slide rail assembly with a synchronization device, including a housing, driving member, actuating member, and synchronization rod, allowing the second rail of the first slide rail assembly to unlock and release elastic force to move synchronously with the second rail of the second slide rail assembly, enhancing stability and reliability of the push-open function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a push-open device is used to assist drawer opening, then the drawer can be opened from a retracted position, but the two slide rail assemblies cannot move synchronously affecting stability
Solution Approach 1:
The patent combines two independent slide rail assemblies with a common synchronization rod that connects both rails. The synchronization rod integrates the movement of both rails, ensuring they move synchronously while maintaining the push-open assistance function. This merging of previously independent components resolves the contradiction between ease of operation and stability.
Solution Approach 2:
The synchronization rod acts as an intermediary component between the two slide rail assemblies. It mediates their movement by providing a mechanical connection that ensures synchronized motion. This intermediary element allows both rails to move together smoothly, maintaining stability while preserving the push-open assistance capability.
2Reliability
If spring-loaded ejectors with latching elements are used, then the drawer can be temporarily locked and ejected, but the mechanism is complex and difficult to manufacture
Solution Approach 1:
The patent extracts the essential locking function from the complex spring-loaded ejection mechanism and implements it through a simpler elastic member with a latching element. By removing unnecessary components and retaining only the core locking functionality, the device achieves reliable locking while significantly reducing manufacturing complexity.
Solution Approach 2:
The patent changes the parameters of the locking mechanism by using a simpler elastic member instead of a complex spring-loaded system. This parameter change maintains the temporary locking reliability while reducing the overall complexity of the ejection device, making it easier to manufacture and assemble.
3Stability of the object's composition
If guide carriages are connected through a synchronization rod, then synchronous movement is achieved, but the device complexity increases
Solution Approach 1:
The patent segments the synchronization mechanism into distinct functional components: the synchronization rod, the connecting arms, and the mounting points on each rail. This segmentation allows for modular assembly and simplifies the overall device complexity while maintaining the synchronous movement capability. Each segment can be manufactured and assembled independently.
