Quick Release Coupling for Linear Guideway Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional linear guideway assembly is time-consuming and costly due to the need for multiple screws and threaded holes for assembling end caps, slide blocks, and nozzle tips, increasing production costs and assembly time.
Innovation Solution
A quick release coupling device with connectors having threaded ends and rotary abutment surfaces that allow for easy assembly by rotating the end caps to create a locking effect, eliminating the need for multiple screws and threaded holes, and enabling the connectors to function as an oil nozzle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple screws and threaded holes are used to assemble end caps to slide block, then the assembly is secure and reliable, but the assembly time and production cost increase significantly
Solution Approach 1:
The connector integrates multiple functions into a single component: it combines the fastening function (replacing multiple screws), the positioning function (locating end caps), and the lubrication function (acting as an oil nozzle) into one unified element that is screwed into the slide block, thereby reducing assembly time while maintaining reliability
Solution Approach 2:
The connector serves multiple purposes simultaneously: it acts as a fastening element to secure end caps, a positioning element to locate them correctly, and a lubrication delivery system (oil nozzle), eliminating the need for separate screws, threaded holes, and nozzle components
2Reliability
If multiple screws and threaded holes are used to assemble end caps to slide block, then the assembly is secure and reliable, but the production cost increases due to additional threaded components
Solution Approach 1:
The connector merges the functions of multiple components (screws, threaded hole features, and nozzle) into a single element, reducing the total number of parts that need to be manufactured, inventoried, and assembled, thereby lowering production costs while maintaining assembly reliability
Solution Approach 2:
By making the connector a multi-functional component that replaces screws, creates positioning features, and provides lubrication delivery, the design reduces the bill of materials and manufacturing complexity, leading to cost savings without compromising the secure assembly of end caps to the slide block
3Ease of operation
If connectors with rotary abutment surfaces are used, then the assembly process is simplified and quick release is enabled, but the connector design becomes more complex
Solution Approach 1:
The connector incorporates a rotary abutment surface with a curved profile (conical, helical, or curved surface) that engages with a corresponding slant abutment surface on the end cap, enabling quick release through rotational motion while maintaining structural integrity and assembly simplicity

AI summary
A quick release coupling device for a linear guideway comprises a rail, a slide block, a pair of end caps and a pair of connectors. Each of the end caps has a through hole in which are annularly arranged a slant rotary abutment surface and a plurality of grooves. The connectors each has an end fixed to the slide block, and another end of the connectors is defined with a wing-shaped portion, the wing-shaped portion has an abutment surface for mating with the rotary abutment surface of the end caps.
