Sliding Gate Runner Rail with Segmented Support
Solution Overview
Problem
Existing sliding gates and doors, especially those for outdoor use, face challenges in achieving a compact, aesthetically pleasing, and highly stable design without the need for support rollers, which often result in unsatisfactory stability and increased substructure height.
Innovation Solution
A device featuring a shorter running rail with rolling or sliding elements attached to its ends, allowing it to be easily moved over a longer rail, with a solid support element that can absorb weight and provide stability, and incorporating spring-loaded rollers to manage heavy loads and prevent tilting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If support rollers are used to enable the gate to move, then the gate can be operated with little force, but the substructure height increases and aesthetic requirements are not satisfied
Solution Approach 1:
The patent transitions from a vertical support structure (rollers positioned one above the other in S-shaped rail) to a horizontal support configuration (shorter running rail with rolling elements at its ends). This dimensional change allows the gate to be supported and moved while maintaining a compact substructure height, resolving the contradiction between ease of operation and aesthetic appearance.
2Reliability
If rollers are positioned one above the other in S-shaped rail, then the gate can be supported, but the substructure height increases and stability deteriorates
Solution Approach 1:
The patent segments the support function by distributing rolling elements at both ends of the shorter running rail, rather than using a single vertical stack of rollers. This segmentation provides stable support while maintaining compact substructure height, eliminating the tendency to tilt during movement.
Solution Approach 2:
The patent changes the spatial arrangement from vertical stacking of rollers to horizontal distribution at rail ends, achieving stable support with reduced substructure height.
3Reliability
If a solid support element is used to absorb weight, then stability improves, but the device complexity increases
Solution Approach 1:
The patent merges the support element with the running rail system, where the shorter running rail is directly supported by the solid support element. This integration provides stable weight absorption while maintaining a simple, compact overall structure, avoiding increased device complexity.
