Built-in Element Wall Connection Segmentation for Burglary Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing built-in elements for separating interior and exterior spaces lack effective burglary protection and optimized installation at low production costs, particularly in their wall connections.
Innovation Solution
A built-in element with a wall connection featuring a profile part with an L-shaped cross section, including a side wall part and a bottom wall part with a fastening opening, utilizing a continuous mounting channel and connector means for enhanced stability and resistance to external forces, and optionally a two-part wall connection with latching mechanisms for increased security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional wall connection is used for fastening the fixed element to the building wall, then the installation is simple, but the burglary protection is insufficient and resistance to external forces is low
Solution Approach 1:
The wall connection is divided into multiple functional components: a wall connection element with fastening means for securing to the building wall, and a separate blocking portion that protrudes into the recess of the fixed element. This segmentation allows each component to be optimized independently - the fastening means provides secure attachment while the blocking portion prevents lever-based break-in attempts, thereby improving burglary protection without requiring complete redesign of the entire wall connection system.
Solution Approach 2:
The wall connection employs a composite structure combining different functional elements - the wall connection element (for fastening) and the blocking portion (for security) work together as an integrated system. This composite approach allows the wall connection to simultaneously provide mechanical fastening strength and anti-burglary functionality, resolving the contradiction between reliability and structural complexity.
2Strength
If a blocking portion protruding into the recess is added to prevent lever-based break-ins, then burglary protection is improved, but the wall connection structure becomes more complex
Solution Approach 1:
The blocking portion is designed as a distinct segment from the wall connection element, allowing it to be integrated into the existing wall connection structure without completely redesigning the system. The blocking portion specifically targets the vulnerability to lever forces by protruding into the recess where such forces would be applied during break-in attempts, providing enhanced strength against these specific forces while minimizing overall structural complexity.
3Temperature
If the fixed element fully covers the fastening element, then aesthetics and thermal insulation are improved, but the stability against external forces may be reduced
Solution Approach 1:
The blocking portion acts as an intermediary element that transfers and distributes external forces (such as wind loads or attempted break-in forces) from the fixed element back to the wall connection element and ultimately to the building wall. This intermediary structure allows the fixed element to cover the fastening element for aesthetic and thermal insulation purposes while maintaining stability against external forces through the force-distributing blocking portion.

AI summary
The invention relates to a built-in element, particularly for mounting on a building wall, for separating an interior from an exterior space, comprising a fixed element and a wall connection for attaching the fixed element to the building wall. According to the invention, a fastening element is provided with a continuous mounting channel for guiding a fastening element, wherein the fastening element can be arranged on the inside of the wall connection and wherein the wall connection can be attached to the building wall via the fastening element guided through a mounting channel of the fastening element, wherein the fixed element, with its open end region, at least partially covers the fastening element and can be connected to the fastening element via a first connector that can be arranged transversely to the fastening element.
