Smart Window Sash Control Integrated Into a Hollow Chamber
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing windows and doors with variable light transmission properties lack integration of control elements, limiting their functionality and requiring standalone controllers that are not integrated into the window, door, or building wall.
Innovation Solution
A multi-part control element is integrated into the window or door, with one part accommodated in a hollow chamber of the sash and another part in the building wall, allowing for a flush-mounted solution with electrical interfaces and BUS connections for power and communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If control elements are integrated into the window or door, then functionality and operational reliability are enhanced, but device complexity increases
Solution Approach 1:
The control element is divided into multiple parts: a first part accommodated in the hollow chamber of the sash and a second part arranged in the building wall. This segmentation allows the control functionality to be distributed across different locations, enhancing integration without concentrating all complexity in one location.
Solution Approach 2:
The first part of the control element is accommodated within the hollow chamber of the sash, utilizing the existing internal space of the window/door structure. This nesting approach integrates the control element without adding external bulk, maintaining aesthetic appearance while enhancing functionality.
2Ease of manufacture
If control elements are integrated into the hollow chamber of the sash, then installation ease is improved, but the hollow chamber space is occupied
Solution Approach 1:
The control element is extracted from the traditional standalone controller form and integrated into the window/door structure itself. By placing the first part in the hollow chamber and the second part in the building wall, the solution eliminates the need for separate external controllers while utilizing existing structural spaces.
Solution Approach 2:
The hollow chamber of the sash, which traditionally serves only as structural support, is repurposed to also accommodate the control element. This multi-functional use of space integrates control functionality without requiring additional dedicated space, thereby improving installation ease while efficiently utilizing existing volume.
3Adaptability or versatility
If a multi-part control element design is used, then integration flexibility is improved, but manufacturing complexity increases
Solution Approach 1:
The control element is segmented into at least two distinct parts that can be manufactured separately and then integrated during assembly. The first part is manufactured to fit within the hollow chamber of the sash, while the second part is manufactured for integration into the building wall, allowing for specialized manufacturing processes for each component.
Solution Approach 2:
The control element parts are designed with pre-defined mounting interfaces and connection points that align with the hollow chamber structure and building wall opening. This preliminary design of integration interfaces simplifies the assembly process, reducing the complexity that would otherwise arise from custom fitting during installation.
