Pet Crate Door Lock Assembly to Prevent Pet Escape
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The door latch of existing pet crates is easily opened by clever pets, leading to their escape.
Innovation Solution
A door lock for a pet crate featuring a rotatably connected door body with a locking assembly, including a fixed member, limiting member, rotating rod, and locking members, which allows for stable fixation and simple operation, preventing pets from opening the door.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple door latch is used, then the device complexity is reduced, but the reliability of preventing pet escape deteriorates
Solution Approach 1:
The locking mechanism is divided into multiple independent components: a locking block with protrusions, a rotating rod, and corresponding grooves in the door body. This segmentation allows each component to perform a specific function while maintaining overall system reliability without excessive complexity
Solution Approach 2:
The locking block is designed to rotate dynamically between locked and unlocked positions. The rotating rod enables the locking block to engage with or disengage from the door body grooves, providing a reliable lock that is simple in structure but effective in function
2Reliability
If a complex locking mechanism is used, then the reliability of preventing pet escape is improved, but the ease of operation deteriorates
Solution Approach 1:
The locking mechanism is designed to be self-locking through the engagement of the locking block protrusions with the door body grooves. Once the rotating rod is turned, the geometry of the components automatically maintains the locked state without requiring additional steps or complex operations
Solution Approach 2:
The locking block features asymmetric protrusions that engage with corresponding asymmetric grooves in the door body. This asymmetric design provides strong mechanical engagement for reliability while allowing operation in a single rotational direction, simplifying the user action required

AI summary
A door lock for a pet crate includes: a crate body provided with an opening; a door body including one end rotatably connected to one side of the opening, and a locking assembly provided at the other end of the door body and connected to the crate body. As the door body is rotatably connected to the crate body, and the door body and the crate body are provided with the locking assembly, the door body can be stably fixed to the crate body through the locking assembly to prevent the pet from pulling the door lock left and right to open the door body. In addition, the locking of the door body can be completed simply by rotating the locking assembly and pulling the locking assembly to the right, making the operation simple.
