Telescopic Slide Rail Locking and Synchronization Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide assembly technologies require high manufacturing costs and complex machining steps due to individually installed locking and synchronizing mechanisms, which are inefficient and costly.
Innovation Solution
A slide assembly with a locking member, synchronizing member, and connection member that synchronizes the movement of inner and middle rails with the outer rail, utilizing a locking and releasing mechanism to allow synchronized and continuous pulling of the inner rail, while reducing the need for complex machining.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If locking and synchronizing mechanisms are individually installed, then the rails can be smoothly moved and synchronized, but the manufacturing cost increases and machining steps become complex
Solution Approach 1:
The locking member integrates both the locking portion (for locking the middle rail to the outer rail) and the synchronizing portion (for synchronizing the inner and middle rails) into a single component. This merging of functions eliminates the need for separate locking and synchronizing mechanisms, thereby reducing manufacturing cost and simplifying machining steps while maintaining the reliability of rail movement and synchronization.
2Manufacturing precision
If a locking mechanism is used to lock the middle rail, then the middle rail can be positioned relative to the outer rail, but the inner rail cannot be continuously pulled without disengagement
Solution Approach 1:
The locking member is designed with movable portions that can dynamically transition between locked and unlocked states. The locking portion can engage with the locking hole to secure the middle rail, while the synchronizing portion can disengage from the connection hole to allow continuous pulling of the inner rail. This dynamic design enables both precise positioning and continuous operation without disengagement.
Solution Approach 2:
The locking member is pre-configured with both locking and synchronizing functions integrated into a single component. The locking portion is positioned to engage the locking hole, while the synchronizing portion is positioned to interact with the connection hole. This preliminary configuration ensures that both positioning and continuous pulling capabilities are built into the structure before operation, eliminating the need for separate mechanisms.
3Reliability
If engaging blocks and holes are used for locking, then the rails can be locked and synchronized, but the device complexity increases due to multiple individual components
Solution Approach 1:
The locking member combines the locking function (via the locking portion engaging the locking hole) and the synchronizing function (via the synchronizing portion engaging the connection hole) into a single integrated component. This merging reduces the number of individual components from multiple separate mechanisms to one unified locking member, thereby reducing device complexity while maintaining both locking and synchronizing functions.

Function Achieved in This Case
The solution enables efficient and cost-effective synchronization of the inner and middle rails with the outer rail, reducing manufacturing costs and simplifying the machining process, allowing for smooth and synchronized movement while maintaining the ability to retract and continuously pull the inner rail.
Implementation Method 1
The locking portion extends through the first hole of the middle rail and resiliently contacts the outer rail
Implementation Method 2
The synchronizing member extends from the fixing portion of the locking member and extends through the second hole of the middle rail and resiliently contacts the outer rail
Implementation Method 3
The protrusion has an inclined surface. A connection member extends from the releasing member and has an end portion and a shoulder portion. The shoulder portion is located corresponding to the protrusion of the synchronizing member

AI summary
A slide assembly and a connection device include an outer rail, a middle rail slidably connected to the outer rail, and an inner rail slidably connected to the middle rail. The middle rail has a locking member and a synchronizing member extends from the locking member. A releasing member is fixed to the inner rail and a connection member extends from the releasing member. The middle and inner rails are synchronously pulled from the outer rail and when the middle rail is positioned at a desired position, the inner rail is continuously pulled out by the connection between the locking member and the outer rail and by the connection member disengaged from the synchronizing member. When the inner rail is retracted relative to the middle rail, the releasing member releases the middle rail from the outer rail and the middle rail is retracted relative to the outer rail.
