Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional metal fixing brackets are used in renovation, then the frame can be secured to the wall, but thermal bridges are created and labor time increases due to complex positioning requirements
Solution Approach 1:
The fixing device is divided into two separate components: a fixing element with anchoring function and a bracket element with receiving function. This segmentation allows each component to be optimized independently and simplifies the installation process by enabling modular assembly rather than requiring precise pre-positioning of a single complex bracket.
Solution Approach 2:
The patent introduces an intermediary fixing element that acts as a mediator between the wall anchoring system and the frame bracket. This intermediary component simplifies the overall installation by providing a standardized interface that reduces positioning complexity and labor time while maintaining fixing reliability.
2Reliability
If traditional metal fixing brackets are used, then the frame can be attached to the wall, but thermal insulation performance deteriorates due to thermal bridging
Solution Approach 1:
The fixing device uses composite construction combining metal structural elements with thermal insulation materials. The bracket and fixing element incorporate insulating properties to break thermal bridges while maintaining mechanical strength for reliable frame attachment, thereby eliminating thermal bridging without sacrificing fixing reliability.
Solution Approach 2:
The patent applies thermal insulation properties specifically at the critical thermal bridging points where the fixing bracket contacts the wall and frame. By localizing insulation materials to these specific areas, the solution addresses thermal bridging without requiring complete insulation of the entire fixing device, maintaining structural integrity while reducing thermal transfer.
3Device complexity
If traditional fixing devices are used without built-in adjustment means, then the device structure remains simple, but anchoring depth precision deteriorates making compliance with minimum requirements difficult
Solution Approach 1:
The fixing element is designed with built-in adjustment means and predetermined anchoring depth features during manufacturing. This preliminary preparation of adjustment mechanisms and depth specifications allows installers to easily achieve precise anchoring without complex field measurements or adjustments, maintaining simple device structure while ensuring anchoring depth precision.
4Device complexity
If traditional fixing devices without integrated insulation are used, then the device structure remains simple, but thermal insulation performance deteriorates
Solution Approach 1:
The patent merges the thermal insulation function directly into the fixing device structure by integrating insulation materials within the bracket and fixing element. This combination of structural and insulating functions in a single integrated component eliminates thermal bridging without requiring separate insulation installations, maintaining relatively simple device structure while achieving thermal insulation performance.
