Two-Way Swinging Door Gap Control for Companion Animals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional door control systems for companion animals are complex, difficult to adjust for varying animal sizes, and often result in inefficient heating and cooling due to frequent door opening, while also failing to provide secure individual living spaces and protect smaller animals from larger ones.
Innovation Solution
A two-way swinging door opening gap control device featuring an adjustable gap control band, a locking pin module with upper and lower pins, and a locking holder module that allows for secure locking and release at a given angle, enabling the device to be installed in both directions without affecting the door's opening direction, thus preventing larger animals from entering and allowing for easy size adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the door is always open to allow companion animals free movement, then the animals can freely enter and exit rooms, but the door becomes frequently completely open which lowers cooling and heating efficiencies
Solution Approach 1:
The patent changes the parameter of door opening gap from completely open to a controlled gap size. The gap control device limits the door opening to a specific angle or gap width, allowing animals to pass through while preventing the door from opening completely, thus maintaining thermal efficiency while enabling animal movement.
2Ease of operation
If the door is always open to allow companion animals free movement, then animals can freely enter and exit rooms, but small-sized animals may be injured in fights with large-sized animals
Solution Approach 1:
The gap control device changes the door opening parameter to a limited gap size that allows small animals to pass through safely while preventing large animals from forcing the door open. The controlled gap creates a size-based access control mechanism that protects small animals from confrontations with larger animals.
3Ease of operation
If a conventional sliding panel door is used to allow animals to enter through the lower portion, then animals can freely enter through the door, but the existing door becomes incised and deformed or requires exchange with a new door
Solution Approach 1:
The patent segments the door control function into two independent parts: the main door structure remains intact, and a separate gap control device is added. This segmentation allows the gap control device to be installed independently without modifying or incising the existing door, preserving the original door structure while enabling animal access control.
4Ease of operation
If a conventional sliding panel door is used to allow animals to enter through the lower portion, then animals can freely enter through the door, but it is not easy to determine the size of the door for the companion animals in accordance with the sizes of the companion animals
Solution Approach 1:
The gap control device introduces dynamic adjustability to the door system. The control device can be adjusted to different gap sizes or opening angles to accommodate companion animals of different sizes, species, and ages. This dynamic adjustment capability provides versatility and adaptability that fixed-size panel doors cannot achieve.

AI summary
Disclosed is a two way swinging door opening gap control device for controlling the movements of companion animals that is detachably attached to the existing door and door frame with ease, without any structural change or damage, thereby being applied conveniently to various types of doors, and that controls an opening gap of the door to allow the companion animals to freely enter through the door, to prevent the door from being excessively opened by external wind or animals entering therethrough, and to limit the spaces the animals can enter according to animal sizes to thus provide individual living spaces for the animals. According to the present invention, the opening gap control device largely includes a gap control band 100, a locking pin module 200, and a locking holder module 300.
