L-Shaped Window Frame Support with Corner Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support elements for window or door frames lack a secure connection between adjacent parts, making pre-assembly before fastening to the masonry challenging and prone to tolerance issues.
Innovation Solution
A support element system featuring L-shaped support parts with a unitary corner bracket and pivotable insulating parts, allowing for secure connection and pre-assembly of the frame before attachment to the wall, with screws and flexible adhesive strips ensuring stability and ease of handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If support parts are connected without a corner bracket, then the device complexity is reduced, but the connection reliability between adjacent support parts deteriorates
Solution Approach 1:
The corner bracket merges multiple functions into a single component: it connects adjacent support parts at right angles, provides a mounting surface for the window frame, and enables pre-assembly. This integration resolves the contradiction by achieving reliable connections without proportionally increasing complexity.
Solution Approach 2:
The corner bracket acts as an intermediary component between adjacent support parts, providing a standardized interface for connection. This mediator enables reliable assembly while keeping individual support parts simple and modular.
2Ease of operation
If support parts are pre-assembled before fastening to masonry, then the ease of operation is improved, but the manufacturing precision requirements worsen due to tolerance accumulation
Solution Approach 1:
The corner bracket incorporates adjustment capabilities that allow tolerance compensation during assembly. By designing the connection parameters (screw holes, mounting surfaces) with built-in adjustment range, the system enables pre-assembly while compensating for manufacturing variations.
Solution Approach 2:
The corner bracket enables preliminary assembly of the support structure before final fixation to the building. This preliminary action allows the frame to be pre-assembled and adjusted, with the bracket serving as a temporary but stable connection element that can accommodate tolerance variations.
3Strength
If insulating parts are made rigid for structural stability, then the strength is improved, but the ease of operation deteriorates due to difficulty in handling and assembly
Solution Approach 1:
The insulating parts are designed to be flexible rather than rigid, allowing them to adapt during assembly and be easily positioned. The flexibility enables simple handling and assembly while the corner bracket and support parts provide the necessary structural stability, separating the structural function from the insulating function.

AI summary
The support element for a window or door frame (34) has two L-shaped support parts (2, 3) arranged perpendicular to each other, and a one-piece corner connector (5) that connects the two support parts (2, 3). The corner connector (5) has four plate sections (22, 24, 26, 28). The first and second plate sections (22, 24) are arranged at right angles to each other, as are the third and fourth plate sections (26, 28). The plate sections (22, 24, 26, 28) are arranged on the facing inner surfaces of the first and second legs (10, 16, 40, 46) of the support parts (2, 3), and the corner connector (5) is attached to the support parts (2, 3).
