Solution Overview
Problem
Existing facade and window panels face challenges in achieving visually appealing ventilation while fulfilling additional functions like decentralized ventilation and solar module integration, as required penetrations can affect the appearance of the facade.
Innovation Solution
A facade or window panel design featuring a cavity ventilated via openings and/or passages between an inner insulating element and an outer cover element, allowing for rear ventilation and air exchange, which can be integrated with decentralized air conditioning and solar modules, with ventilation openings strategically placed to maintain a uniform facade appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If ventilation openings are created in the panel to enable ventilation functions, then ventilation efficiency is improved, but the visual appearance of the facade is worsened
Solution Approach 1:
The ventilation openings are extracted from the visible facade surface and relocated to the cavity space between the inner and outer cover elements. This allows the ventilation function to be performed while keeping the external facade surface intact and visually appealing, resolving the contradiction between ventilation efficiency and aesthetic appearance.
Solution Approach 2:
The ventilation openings are moved from the two-dimensional facade surface to the three-dimensional cavity space. By placing openings in the legs of edge-side supports that face the cavity rather than the external surface, the patent utilizes the depth dimension of the panel construction to achieve ventilation without compromising the visual appearance of the facade.
2Productivity
If the outer cover element is held at a distance from the inner insulation element to create a ventilated cavity, then ventilation capability is improved, but the structural complexity is worsened
Solution Approach 1:
The edge-mounted supports serve multiple functions: they mechanically hold the outer cover element at a distance from the inner insulation element to create the cavity, provides structural support for the panel, and incorporate ventilation openings in their legs to enable air flow. By combining these functions in a single component, the patent reduces overall structural complexity while achieving ventilation capability.
Solution Approach 2:
The patent merges the support function and ventilation function into a single integrated component - the edge-mounted support with openings in its legs. This combination eliminates the need for separate support elements and ventilation structures, thereby reducing structural complexity while maintaining both support and ventilation capabilities.
