Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rail clamps for linear transmission systems are difficult to assemble and disassemble, prone to loosening, and require frequent replacement due to wear and tear of locking components.
Innovation Solution
A retaining device comprising a sliding block with an upper retainer and a rail clamp connected by spring fasteners, allowing easy assembly and disassembly with elastic members that securely engage and disengage from the sliding block without the need for rotating components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the conventional rotary block retaining device is used to fix the rail clamp on the sliding block, then the rail clamp can be fixed, but the assembly and disassembly process becomes complex requiring rotation operations
Solution Approach 1:
The invention extracts the rotary block mechanism from the retaining device, removing the complex rotation operation. Instead, it uses a simple push-button release mechanism where the button can be pressed to disengage the locking members from the locking grooves, enabling easy removal without rotation operations.
Solution Approach 2:
The invention inverts the conventional approach by using elastic members that automatically engage with locking grooves when the button is released, rather than requiring active rotation to lock. The elastic members provide automatic locking through their inherent elasticity, reversing the need for manual rotation operations.
2Reliability
If the locking members and locking grooves are used to position the rotary blocks, then the retaining device can be fixed, but the components wear out after a certain period requiring replacement
Solution Approach 1:
The invention changes the physical state of the retaining members from rigid to elastic. The elastic members can deform during engagement and disengagement, absorbing wear and stress without permanent damage. This elastic deformation capability extends the service life by allowing the components to accommodate wear through reversible deformation rather than irreversible wear.
Solution Approach 2:
The elastic members provide beforehand cushioning by absorbing impact and wear forces during engagement and disengagement operations. The elasticity of the members cushions the mechanical stress that would otherwise cause wear to the locking grooves and retaining members, thereby extending the overall service life of the retaining device.
3Reliability
If the rotary blocks are rotated upward to fix the retaining device, then the rail clamp is secured, but the device cannot perfectly mate with the sliding block and becomes loose
Solution Approach 1:
The invention changes the engagement mechanism from rigid rotary block rotation to elastic member engagement. The elastic members can deform to accommodate slight variations in manufacturing tolerances between the rail clamp and sliding block, ensuring perfect mating without requiring extremely precise manufacturing. The elasticity allows the components to self-adjust to achieve optimal contact.
Solution Approach 2:
The invention applies local quality by making only the engagement points (retaining members and locking grooves) elastic, while the rest of the structure remains rigid. This localized elasticity at the contact points allows for accommodation of manufacturing variations without compromising the overall structural integrity and precision of the rail clamp assembly.

AI summary
A retaining device for a linear transmission system comprises: a sliding block, a rail clamp and a spring fastener The sliding block includes an upper retainer formed with a positioning hole. The rail clamp includes two retaining members and two elastic members, and the two retaining members are symmetrically arranged and are connected by the two elastic members. The two elastic members can adjust the interval between the two retaining members. The spring fastener is pivotally arranged between the two retaining members of the rail clamp and is provided with two elastic retaining portions to be engaged in the positioning hole of the upper retainer. After the rail clamp is installed in the sliding block, the two elastic members of the spring fastener will be engaged in the positioning hole, thus fixing the rail clamp in the sliding block.
