Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If LED lighting system is integrated into insulating glazing, then optical performance and energy efficiency are improved, but thermal bridge formation and structural complexity increase
Solution Approach 1:
The lighting system is segmented into modular components: PCB devices carrying LED strings are separated from the glazing assembly and mounted on external profiles. This allows the glazing to maintain its insulating integrity while the lighting function is provided by attachable modules that can be independently replaced or maintained.
Solution Approach 2:
Thermally insulating profiles act as intermediaries between the glazing and the PCB devices. These profiles provide mechanical support and electrical connection pathways while thermally isolating the conductive PCB mounts from the glass edges, preventing thermal bridge formation.
2Device complexity
If PCB devices are directly mounted on glazing edges, then device complexity is reduced, but thermal bridges are created
Solution Approach 1:
Thermally insulating profiles serve as intermediary elements between the glazing edges and the PCB device mounting points. The profiles are made of thermally insulating materials and include integrated mounting features that attach the PCB devices without creating direct thermal pathways through the glass edges.
Solution Approach 2:
The profiles provide localized thermal insulation at critical mounting points where PCB devices attach to the glazing assembly. The insulating material is concentrated at the interface between the PCB mounts and the glass edges, providing thermal break functionality exactly where needed.
3Illumination intensity
If LED strings are closely positioned to glazing, then illumination intensity is improved, but risk of impact damage and thermal issues increases
Solution Approach 1:
The PCB devices are mounted on profiles that extend perpendicular to the glazing surface, positioning the LED strings in a third dimension away from the glass. This spatial separation reduces impact risk while maintaining illumination effectiveness through proper optical design of the LED arrangement and diffuser elements.
