Spring Biased Sliding Door Closing System for Wire Mesh Enclosures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated door systems for wire mesh enclosures often require manual operation, leading to forgotten closed positions, which can result in unauthorized access and theft.
Innovation Solution
An automated sliding door closing system with a spring biased mechanism, such as a hydraulic door closer, connected to a sliding door track and a connection arm that rotates to close the door after it has been opened, ensuring the door is locked shut.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual door operation is used, then device complexity is reduced, but reliability of door closure is worsened due to user forgetfulness
Solution Approach 1:
The door closing mechanism operates automatically without requiring user intervention. The spring-loaded arm self-activates when the door is opened, propelling itself to push the door closed, thereby eliminating reliance on user memory while maintaining relatively simple mechanical construction
Solution Approach 2:
The spring mechanism is pre-loaded during door installation and operation. When the door is opened, the pre-stored elastic energy in the spring is released to automatically push the door closed, ensuring closure action occurs before any potential security breach can occur
2Reliability
If automated closing mechanism is added, then door closure reliability is improved, but device complexity increases
Solution Approach 1:
The closing function is extracted as a separate, independent mechanical subsystem (spring-loaded arm) that operates autonomously from the door structure. This modular approach ensures reliable automatic closure while keeping the overall system complexity manageable through functional separation
Solution Approach 2:
The spring-loaded arm acts as an intermediary mechanical element between the opened door position and the closed door position. It mediates the transition by converting rotational motion into pushing force, ensuring reliable closure without requiring complex control systems
3Object-affected harmful factors
If manual door operation is used, then ease of operation is maintained, but security is worsened due to forgotten door closure
Solution Approach 1:
The door closing function serves itself automatically through the spring mechanism without requiring user action. This maintains ease of operation (users can still open the door freely) while eliminating the security risk of forgotten closure, as the system self-closes after each opening event
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 ensures the sliding door is automatically closed and locked, preventing unauthorized access and enhancing security by eliminating the need for manual operation.
Implementation Method 1
A spring biased closing mechanism is connected to the sliding door track
Implementation Method 2
In a preferred embodiment the spring biased closing mechanism is a hydraulic door closer

AI summary
An automated sliding door closing system to be used with wire mesh enclosures. The door closing system includes support brackets with wire mesh connected between the support brackets. A sliding door track is connected to the support brackets. Sliding door connection bolts slide within the sliding door track and support a sliding door. A spring biased closing mechanism is connected to the sliding door track. The spring biased closing mechanism is biased to keep the sliding door closed. A door roller track is rigidly connected to the sliding door. A connection arm is connected between the spring biased closing mechanism and the door roller track. The connection arm includes a roller inserted into the door roller track. A strike plate is rigidly connected to one of the wire mesh support brackets. The connection arm rotates to close the sliding door after the sliding door has been opened.
