Wire Pet Crate Door Vertical Slide Catch Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pet enclosures, such as crates and exercise pens, often lack secure and user-friendly door mechanisms that prevent pets from escaping while allowing easy access for owners, particularly in designs featuring wire structures.
Innovation Solution
A wire enclosure with a slide apparatus and catch system that includes a finger receptor and stationary pieces, allowing the door to be easily opened from the outside but securely locked from the inside, utilizing a two-step process involving the pivoting of a finger receptor and sliding of a vertical slide to engage and disengage catches, ensuring the door can only be opened with intentional operation by the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple door mechanism is used in a wire enclosure, then ease of manufacture and device simplicity are improved, but security against pet escape deteriorates
Solution Approach 1:
The patent employs a dynamic catch mechanism where a slideable catch member moves between engaged and disengaged positions. The catch is biased by a spring to automatically engage with the door, creating a self-latching system that is both secure and simple. This dynamic element provides reliability without complex manual operation.
Solution Approach 2:
The door mechanism is designed to be self-latching through the spring-biased catch that automatically engages with the door when closed. The system serves itself by maintaining the closed state without requiring active engagement from the user, while still allowing easy opening when needed.
2Reliability
If a secure lock mechanism is implemented to prevent pet escape, then reliability is improved, but ease of operation by owners deteriorates
Solution Approach 1:
The slideable catch member provides a simple linear motion for opening the door, contrasting with complex locking mechanisms. The spring bias ensures automatic engagement, while the slideable nature allows easy disengagement by owners through simple pushing or pulling motion.
Solution Approach 2:
The door mechanism is segmented into distinct functional elements: the catch member, the spring bias, and the slideable component. This segmentation allows each element to perform its specific function efficiently, with the catch providing security and the slideable mechanism providing ease of operation.
3Reliability
If a vertical slide catch apparatus is added to the door, then security against unauthorized opening is improved, but device complexity increases
Solution Approach 1:
The vertical slide catch apparatus uses a spring-biased dynamic system where the catch automatically engages and disengages. This eliminates the need for complex manual locking mechanisms while maintaining security, as the spring ensures reliable engagement without requiring additional components.
Solution Approach 2:
The patent merges the catching function and the latching function into a single integrated slideable catch member. The spring bias is incorporated directly into the catch mechanism, combining multiple functions into one component to reduce overall device complexity.

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 solution provides a secure and easy-to-operate door mechanism that is difficult for pets to open but simple and intuitive for owners, ensuring safety and convenience while minimizing protrusion inside the enclosure to avoid harming the pet.
Implementation Method 1
the vertical slide being drawable down by gravity to engage the first catch to the second catch

AI summary
The present wire enclosure includes a door formed of wire and a wall formed of wire. The door includes a door catch. The wall includes a wall catch. The respective catches engage and disengage each other through the employment of a vertical slide having the door catch. A finger receptor when pulled up in turn pulls up the vertical slide to disengage the catches. When in a down position, the finger receptor prevents the vertical slide from being pulled up.
