Pry-Resistant Enclosure Door With Angled Flange Channel Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective enclosures are vulnerable to pry attacks, and the addition of mechanized bolts to counter this increases production costs and complexity without fully addressing the vulnerability between bolts.
Innovation Solution
A protective enclosure design featuring angled flanges extending from the door into channels within the housing when closed, combined with a locking mechanism using actuating bolts, to resist pry attacks by creating a secure interface that prevents forced opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanized bolts are added to counter pry attacks, then the resistance to pry attacks is improved, but the device complexity and production cost increase
Solution Approach 1:
The patent extracts the essential anti-pry function from complex mechanized bolt systems and implements it through simple angled flanges that are integrally formed with the door. These flanges engage with channels in the housing to provide pry resistance without requiring complex moving parts, motors, or actuators. The solution takes out only the necessary structural elements (angled flanges and channels) while eliminating unnecessary complexity.
Solution Approach 2:
The patent replaces expensive, complex mechanized bolt systems with simple, inexpensive angled flanges made from the same material as the door. These flanges are integrally formed and require no additional manufacturing steps, materials, or assembly operations. The solution uses the least complex possible structure to achieve the anti-pry function, effectively using a simple structural feature rather than a complex mechanical system.
2Reliability
If mechanized bolts are used to prevent pry attacks, then security is improved, but the manufacturing cost increases
Solution Approach 1:
The patent merges the anti-pry function into the basic door structure by integrally forming angled flanges as part of the door itself. The flanges are formed from the same material in the same manufacturing process as the door, eliminating the need for separate parts, materials, and assembly operations. This merging of functions reduces manufacturing complexity and cost while maintaining security.
Solution Approach 2:
The angled flanges are self-forming structural features that require no additional manufacturing steps, materials, or assembly operations. The door structure itself provides the anti-pry function through its geometric design rather than requiring separate mechanical components. The solution is self-contained and self-sufficient, providing security through the basic door construction.

AI summary
A protective enclosure including a housing defining a door opening is provided. A first flange extends from an opening end of a door and is angled relative to a surface of said door inwardly toward an interior storage space of the enclosure. The first flange and the door surface form an obtuse angle. A second flange extends from a hinge end of the door and is angled relative to the door surface inwardly toward the interior storage space. The second flange and the door surface form an obtuse angle. A hinge pivotally mounts the door with the housing. A locking mechanism selectively locks the door to the housing. The housing includes a channel disposed along at least a portion of the door opening. At least a portion of the first and second flanges are disposed within the channel when the door is closed to resist pry attacks.
