Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Extendable slide rails face issues with poor connection and stability during the extension process due to inadequate linkage between multiple slide rails.
Innovation Solution
The implementation of a slide rail system comprising a first rail, a second rail, a third rail, a first resilient member, a second resilient member, and a locking member, where the first resilient member drives the second resilient member to move the second rail along the third rail, utilizing a receiving slot and a through slot mechanism with hooks and springs to ensure stable extension and retraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If multiple slide rails are connected during extension, then the extension length is increased, but the connection stability and reliability deteriorate
Solution Approach 1:
The slide rail system is divided into multiple independent but connectable segments (first slide rail, second slide rail, third slide rail) that can be linked together through standardized connection interfaces. Each segment maintains its structural integrity while enabling extended reach when connected in sequence, resolving the contradiction between increased extension length and connection reliability.
Solution Approach 2:
The slide rails are designed with nested structures where inner rails can extend within outer rails, and connection components are integrated within the rail bodies. The connection interfaces are embedded within the rail structures, allowing multiple rails to nest and connect smoothly while maintaining stability through the nested configuration.
2Reliability
If resilient members and locking mechanisms are added to improve connection stability, then the reliability improves, but the device complexity increases
Solution Approach 1:
The resilient members and locking mechanisms are merged into integrated connection assemblies that are built into the rail structures. Rather than adding separate independent components, the locking features and resilient elements are combined with the rail bodies and connection interfaces, achieving enhanced reliability while minimizing the increase in overall device complexity.
Solution Approach 2:
The connection system incorporates self-locking and self-adjusting features where the resilient members automatically engage with locking mechanisms during the extension process. The design allows the connection components to service themselves through automatic engagement and disengagement without requiring external intervention or complex control systems.

Function Achieved in This Case
This configuration enhances the stability and smooth extension of the slide rail by maintaining secure connections between the rails, preventing jamming and ensuring reliable movement, while also reducing friction through the use of a resisting portion.

AI summary
A slide rail includes a first rail, a second rail, a third rail, a first resilient member, a second resilient member, and a locking member. When the first rail is pulled out, the first resilient member drives the second resilient member to move along with the first resilient member to pull the second rail. When a receiving slot is aligned with a through slot, a spring piece and the locking member fall into the through slot, the spring piece separates from the first resilient member, the locking member latches onto a first step surface of the through slot to limit movement of the second rail, and the first rail continues to move.
