Door Edge Reinforcement Braces for Structural Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional door assemblies are inadequate in resisting excessive force, as they can conduct heat, interfere with door operation, and fail to effectively reinforce the door, leading to structural damage and unauthorized entry.
Innovation Solution
A door assembly with hinge-side and lock-side reinforcement braces made of metal, which are attached to the door to provide additional support without extending beyond the exterior surface, thereby enhancing the door's resistance to force and maintaining a seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a U-shaped metal escutcheon plate is used to reinforce the door, then the door's resistance to excessive force is improved, but the plate conducts heat through the thermal barrier and interferes with smooth door swinging operation
Solution Approach 1:
The reinforcement is divided into separate components: an interior reinforcement structure attached to the interior surface and edge surface, and a separate exterior reinforcement structure attached to the exterior surface. This segmentation allows each component to perform its function without the other's harmful effects, particularly preventing thermal conduction paths while maintaining structural strength.
Solution Approach 2:
The interior reinforcement structure acts as an intermediary between the door edge surface and the exterior reinforcement structure. It provides structural support and reinforcement without directly contacting the exterior surface, thereby interrupting thermal conduction paths while still providing the necessary structural integrity to resist excessive force.
2Strength
If a strike plate with transverse projection is used to reinforce the door, then the door's structural resistance is improved, but the strike plate does not effectively restrict damage to the door itself
Solution Approach 1:
The reinforcement structure extends along the edge surface of the door in addition to the interior surface, creating a three-dimensional reinforcement zone that wraps around the door edge. This multi-dimensional approach ensures that damage is restricted to specific localized areas rather than propagating across the door surface, improving reliability by containing potential damage zones.
3Strength
If reinforcement structures are added to the door, then the door's resistance to excessive force is improved, but the device complexity increases
Solution Approach 1:
The interior reinforcement structure and edge reinforcement elements are merged into a single integrated component that is attached to both the interior surface and the edge surface of the door. This merging reduces the number of separate parts and simplifies installation while maintaining comprehensive reinforcement coverage, thereby reducing device complexity.

AI summary
A door assembly for presenting a closeable doorway opening includes a door and a door reinforcement brace. The door is operable to be swingably mounted for swinging movement into and out of a closed position in which the door is located generally within the doorway opening. The door presents opposite interior and exterior surfaces and a perimetric edge surface. The brace is attached to the door to overlie at least portions of the interior and edge surfaces to reinforce the door, with no part of the door reinforcement brace extending exteriorly beyond the exterior surface of the door.
