Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding gates with lengths exceeding 10 m lack satisfactory crash resistance, often experiencing damage or failure under heavy direct impacts, which compromises the security of restricted areas by allowing unauthorized access.
Innovation Solution
A sliding gate design featuring multiple locking bodies on each gate part, with securing elements that transmit forces across different levels, ensuring the gate remains locked and secure even under heavy impact, utilizing reinforced materials and structures to distribute forces effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single locking body is used in existing sliding gates, then the device complexity is reduced, but the crash resistance and reliability deteriorate under heavy impact forces
Solution Approach 1:
The locking device is segmented into multiple locking bodies (at least two first locking bodies and at least one second locking body) distributed at different locations and/or heights on the gate parts. This segmentation allows the impact force to be distributed across multiple locking points, preventing any single locking body from bearing the full force and failing. Each locking body defines a passage that receives the securing element, creating redundant locking paths that enhance overall reliability under impact.
2Reliability
If multiple locking bodies are introduced to improve crash resistance, then the reliability improves, but the device complexity increases
Solution Approach 1:
Multiple locking bodies are designed with identical or similar structures, each defining a passage that receives the same type of securing element. This multi-functionality approach means that while there are multiple locking bodies, each one performs the same basic function of receiving the securing element. The securing element itself serves multiple functions by passing through multiple passages in sequence, locking multiple gate parts simultaneously. This universal design minimizes the increase in complexity compared to having fundamentally different locking mechanisms.
3Reliability
If locking bodies are positioned at different levels, then the force distribution and crash resistance improve, but the manufacturing precision requirements increase
Solution Approach 1:
The locking bodies are positioned at different vertical levels (heights) relative to the ground or supporting surface, utilizing the vertical dimension to distribute impact forces. Instead of only horizontal distribution, the multi-level arrangement creates a three-dimensional locking structure where the securing element passes through passages at different heights. This dimensional approach to force distribution enhances crash resistance by engaging multiple structural points of the gate and supporting structure, while the vertical spacing provides natural tolerance for manufacturing variations.

AI summary
This invention relates to a security sliding gate comprising a first (A) and a second gate part (B) which are slidably movable between an open position and a closed position and a locking device (20-26) for maintaining the gate parts (A),(B) in the closed position, the first gate part (A) comprising at least one first locking body (20-22) defining a first passage (20c-22c), at least one second locking body (23-25) defining a second passage (23c-25c) and a securing element (26), such that, when the gate parts (A), (B) are in the closed position, the first (20c- 22c) and second passages (23c-25c) are aligned in a substantially vertical direction, allowing the securing element (26) to extend through said passages (20c-25c). The locking bodies preferably extend in the space (17) between the end sides (18),(19) of the respective gate parts (A),(B).
