Slide Rail Abutting Layout for Smooth Sliding Without Rattle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide structures require strict dimensional accuracies for projecting and convex portions to smoothly slide and suppress rattling, increasing design and production complexity.
Innovation Solution
A slide structure with guide wall portions featuring convex abutting portions at intervals, where the second abutting portion is positioned separately in the longitudinal and orthogonal directions, allowing the slider to smoothly slide and suppress rattling without strict projection amount requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If strict dimensional accuracies are required for projection amounts of the three projecting portions and three convex portions, then smooth sliding and rattling suppression are achieved, but design and production complexity increases
Solution Approach 1:
The patent transitions from a single-file arrangement of abutting portions to a two-dimensional grid pattern where first and second abutting portions are arranged in different directions on the guide wall face. This spatial reconfiguration allows the system to achieve stable slider support without requiring strict dimensional control of individual projection amounts, as the distributed multi-directional support geometry inherently provides stability.
2Device complexity
If three projecting portions and three convex portions are arranged in a single file, then the structure is simple, but the slider cannot smoothly slide and rattling occurs
Solution Approach 1:
The patent arranges the abutting portions in a two-dimensional pattern rather than a single file. Specifically, first abutting portions extend in one direction while second abutting portions extend in another direction on the guide wall face, creating a grid-like support structure that provides stable, multi-directional support for the slider during movement.
Solution Approach 2:
Different regions of the guide wall face are assigned different functions through the directional arrangement of abutting portions. The first abutting portions provide support in one direction while the second abutting portions provide support in another direction, creating localized support zones that collectively ensure smooth sliding and suppress rattling.

AI summary
A slide structure includes a slide rail and a slide lid. The slide rail includes guide wall portions disposed in a first direction orthogonal to a rail longitudinal direction. A first abutting portion is provided in a guide wall face, and a second abutting portion is provided at a position separated in the rail longitudinal direction relative to the first abutting portion, and separated in a second direction orthogonal to the rail longitudinal direction and the first direction. The slide lid can slide along the rail longitudinal direction between the guide wall portions. A first projecting portion abutting against a top portion of the first abutting portion is provided on one side in a sliding direction, and a second projecting portion abutting against a top portion of the second abutting portion in a state wherein the first projecting portion abuts against the first abutting portion is provided.
