Ground-Anchored Shoe Mechanism for Sliding Gate Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sliding gate mechanisms require a homogeneous ground surface for operation, leading to space inefficiency and high stress on the gate arm, which can result in breakdowns due to cantilevered suspension.
Innovation Solution
A guiding mechanism featuring shoes anchored to the ground with a rectilinear rail system that allows horizontal translation of the gate, eliminating the need for cantilevered support and distributing stress across multiple shoes for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the gate panel is mounted to slide directly on the ground surface, then the mechanism is simple, but it requires homogeneous ground surface and cannot adapt to variations
Solution Approach 1:
The patent introduces shoes as intermediary elements between the gate panel and the ground surface. These shoes are anchored to the ground and provide a stable interface that accommodates ground variations without requiring the gate panel to directly contact the uneven surface, thus resolving the contradiction between adaptability and simplicity.
Solution Approach 2:
The guidance mechanism is segmented into multiple independent shoes distributed along the gate panel's path. Each shoe independently handles local ground variations, allowing the system to adapt to uneven surfaces while maintaining overall simplicity through modular, repeatable units.
2Adaptability or versatility
If a self-supporting gate panel carried by an extended arm is used, then ground surface variations are overcome, but significant footprint and high stress on gate arm occur
Solution Approach 1:
The shoes act as mediators that transfer the gate panel's weight and movement forces directly to the ground through anchored points, rather than requiring the gate arm to bear the full cantilevered load. This significantly reduces stress on the gate arm while maintaining the ability to overcome ground variations.
3Adaptability or versatility
If a self-supporting gate panel carried by an extended arm is used, then ground surface variations are overcome, but significant footprint is imposed
Solution Approach 1:
The mechanism is divided into multiple small, distributed shoes rather than a single large extended arm structure. This segmentation allows the shoes to be positioned compactly along the gate panel's path, minimizing the overall footprint while still providing adequate support to handle ground variations.
4Ease of operation
If the gate panel slides directly on the ground, then the mechanism is simple, but it cannot operate on uneven surfaces
Solution Approach 1:
The shoes serve as simple intermediary elements that enable the gate panel to operate on uneven surfaces without requiring complex active adjustment mechanisms. Each shoe is a passive, anchored element that naturally accommodates local ground variations through its design, maintaining ease of operation while improving surface adaptability.
