Low Profile Canine Door Security System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security systems do not effectively address the need for a low-profile, secure access solution for canine entry and exit in building structures, lacking in design that balances security with ease of use and resistance to tampering.
Innovation Solution
A method and apparatus for a low-profile secure canine access system involving a vertically oriented access opening in a building wall with a door structure and security members, including a flange, orthogonal frame panel, security hinges, and a low-profile bolt receiver, along with a self-contained locking mechanism, designed to provide secure and tamper-resistant access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional security door system is installed for canine access, then security protection is improved, but the profile height increases and complexity increases
Solution Approach 1:
The security system employs nested structures where the door panel is received within a door frame, and security hinges are received within hinge receivers. The bolt receiver is integrated into the door frame structure, creating a compact nested arrangement that reduces overall profile height while maintaining security functionality.
Solution Approach 2:
The invention transitions from a conventional protruding security door design to a low-profile design by redistributing components in the depth dimension. The flange extends outward to provide mounting surface area, allowing the main security components to be positioned closer to the wall surface, effectively reducing the profile height in the primary dimension of concern.
2Strength
If a robust security system with thick components is used, then security protection is improved, but the profile height increases
Solution Approach 1:
The design applies local quality by concentrating structural strength at critical locations rather than uniformly thickening all components. The flange provides localized mounting strength, the bolt receiver provides localized locking strength, and the hinge receivers provide localized hinge support, allowing thin-walled construction elsewhere while maintaining overall security.
Solution Approach 2:
The system employs composite construction with the door panel, door frame, flange, and security components working together as an integrated assembly. The combination of these elements creates a composite security structure where the overall strength exceeds the sum of individual components, enabling reduced thickness while maintaining security performance.
3Reliability
If conventional security hinges are used, then security protection is improved, but the system becomes more vulnerable to tampering with tools like bolt cutters
Solution Approach 1:
The design converts the potential vulnerability of external hinges into a security advantage by enclosing them within recessed receivers. The receivers protect the hinge mechanisms from external access, transforming what would be an exposed vulnerability into a protected feature. The hinge joints are concealed within the door frame structure, making them inaccessible to bolt cutters and other tampering tools.
4Length of stationary object
If a low-profile design is implemented, then the aesthetic and space requirements are improved, but security protection may be compromised
Solution Approach 1:
The security system is segmented into distinct functional components: flange for mounting, door frame for structure, door panel for closure, bolt receiver for locking, and hinge receivers for pivoting. This segmentation allows each component to be optimized for its specific function while contributing to the overall low-profile design, ensuring security is not compromised by the reduced size.

AI summary
A method to provide in a wall of a building structure a low-profile secure canine access comprises the steps of forming an access opening through the wall, mounting a door structure in the wall, and installing a supplemental security member over the door structure to fully enclose the door structure. A door is mounted in the security member. A low profile locking system secures the door in a closed position.
