Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-lubricating units in linear sliding rails cannot adjust the lubricant amount in real-time, requiring detachment and replacement to adapt to changing loads, leading to inefficiencies, increased costs, and maintenance challenges.
Innovation Solution
A self-lubricating unit with a lubricant tank and adjustable pressing bodies that allow continuous lubricant amount adjustment without detaching the sliding rail, using capillarity and screws with adjustment bolts to control the lubricant output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed lubricant amount is supplied by the self-lubricating unit, then the lubricating system is simple and easy to manufacture, but it cannot adapt to changing load requirements without detachment and replacement
Solution Approach 1:
The pressing body is designed to be adjustable in position along the sliding rail, allowing the lubricant supply amount to be dynamically changed according to load requirements. The pressing body can be moved to different positions to press the lubricant-containing device with different forces, thereby adapting to various lubrication needs without replacing the entire self-lubricating unit.
Solution Approach 2:
The lubricant supply amount is controlled by changing the pressing force applied by the pressing body on the lubricant-containing device. By adjusting the position or force of the pressing body, the parameter of lubricant supply rate can be varied to match different load conditions, providing adaptability without increasing overall system complexity.
2Adaptability or versatility
If the self-lubricating unit is detached and replaced to adjust lubricant amount, then the lubricant supply can be adapted to new working states, but the process time is wasted and working efficiency is reduced
Solution Approach 1:
The pressing body is designed with adjustable positioning capability that allows operators to modify the lubricant supply amount in-place during operation. This dynamic adjustment mechanism eliminates the need to detach and replace the entire self-lubricating unit, thereby maintaining continuous production and improving working efficiency.
Solution Approach 2:
The pressing body serves multiple functions: it provides continuous pressing force on the lubricant-containing device, allows adjustable positioning for different lubrication rates, and can be repositioned without detachment. This multi-functionality enables adaptation to new working states while maintaining system integrity and productivity.
3Quantity of substance
If a fixed amount of lubricant is supplied, then the self-lubricating unit structure is simple, but lubricant waste occurs when larger loads require more lubricant
Solution Approach 1:
The lubricant supply amount is made variable by adjusting the pressing body's position or force on the lubricant-containing device. This allows the system to match lubricant supply to actual load requirements, preventing waste when loads are high and ensuring adequate lubrication when loads are low, thereby optimizing lubricant utilization.
Solution Approach 2:
The pressing body is designed to work in conjunction with the lubricant-containing device to automatically regulate lubricant flow based on the pressing force applied. This self-regulating mechanism ensures that lubricant is supplied in the appropriate amount without external intervention, reducing waste while maintaining adequate lubrication.

AI summary
A linear sliding rail has a self-lubricating unit capable of adjusting a lubricant amount supplied therefrom. The linear sliding rail has a sliding body and a lubricant tank fitted thereon. Within the lubricant tank, a lubricant-containing device is received, through which a lubricant is released to lubricant the sliding rail. Within the lubricant tank, there are also pressing bodies. Screws are used to assemble the components in the self-lubricating unit and penetrate and protrude the tank cover so that a distal end of each of the screws may be connected with an adjustment bolt. Thus, the purpose of lubricant amount adjustment may be achieved by placing the pressing bodies against the lubricant-containing device at different levels according to the user's requirement.
