A sliding screen sliding system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding screen systems face challenges with high sliding resistance, especially at start-stop positions, due to dust sensitivity and friction issues in ball bearings and linear plain bearings, which are exacerbated in heavier doors like glass patio doors and wardrobe doors.
Innovation Solution
A sliding screen system with a linear slide bar coated with a lacquer comprising a resin and a lipophilic composition coating, providing a low-friction interface for sliding members, which reduces dynamic friction by up to 75% and remains effective over a long duration without the need for replenishment, even in the presence of contaminants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If ball bearings are used for sliding doors, then the doors are easily moveable with low start-stop resistance, but they are dust sensitive and require frequent maintenance
Solution Approach 1:
The patent introduces an intermediary substance (lipophilic coating) between the sliding surfaces to eliminate direct metal-to-metal or metal-to-plastic contact. This coating layer acts as a mediator that provides low friction while being insensitive to dust contamination, resolving the contradiction between ease of movement and dust sensitivity
Solution Approach 2:
The patent replaces the mechanical ball bearing system with a plain sliding surface treated with lipophilic coating. This substitution eliminates the complex mechanical structure of ball bearings while achieving comparable or superior performance in terms of dust resistance and ease of movement
2Object-affected harmful factors
If linear plain bearings are used for sliding doors, then dust sensitivity is reduced, but sliding resistance becomes too high for practical use
Solution Approach 1:
The patent changes the surface parameters of the linear plain bearing by applying a lipophilic coating. This chemical/physical modification of the surface properties dramatically reduces the friction coefficient, making plain bearings suitable for heavy doors while maintaining dust resistance
Solution Approach 2:
The patent creates a composite surface structure combining the base material (metal or plastic) with a lipophilic coating layer. This composite structure provides the benefits of both materials: the structural integrity of the base material and the low-friction, dust-resistant properties of the lipophilic coating
3Adaptability or versatility
If heavier doors are used for patio doors and wardrobe doors, then functionality is improved, but sliding resistance increases making movement difficult
Solution Approach 1:
The patent changes the friction parameter of the sliding interface through lipophilic coating, enabling heavy doors to slide easily. The coating reduces the coefficient of friction sufficiently to handle the increased weight while maintaining functionality
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system achieves low and consistent sliding friction, reducing start-stop resistance and maintaining performance over extensive use cycles, making it suitable for heavier doors and applications where dust and contamination are concerns.
Implementation Method 1
a linear slide bar (10; 110; 210; 310) having a slide surface (14) coated with a lacquer (16) comprising a resin, the lacquer (16) in turn being at least partly coated with a lipophilic composition coating (18) to provide a slide layer (19) with lowered friction

AI summary
A sliding screen system (101) for a sliding screen comprising a linear slide bar (110) and at least one sliding member (120, 120'). The linear slide bar (110) has a slide surface coated with a lacquer comprising a resin. The lacquer is in turn at least partly coated with a lipophilic composition coating. The lipophilic composition coating provides a slide layer on the slide bar (110) with low friction. The sliding system (101) is arranged to support a sliding screen (130), such as a sliding door or a sliding curtain, connected to the sliding member (120) to allow for linear movement of the sliding screen (130) along the longitudinal axis of the linear slide bar (110).
