Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart doors with changeable light permeability properties require external control elements that cannot be integrated into the door structure, necessitating complex installation and significant interventions in building structures.
Innovation Solution
A door design where the control element is integrated into the door wing, allowing for installation during manufacturing and simplifying site assembly, with electrical interfaces for voltage supply and control commands, and optionally including sensors for smart home integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If external control elements are used for windows with variable light transmission properties, then the control function is achieved, but the installation complexity increases and building structure interventions are required
Solution Approach 1:
The control element is integrated into the door leaf structure, merging the control function with the door assembly. This eliminates the need for separate external control elements and their associated mounting infrastructure, directly reducing installation effort and complexity while maintaining all control functionalities
Solution Approach 2:
The door leaf serves multiple functions: it provides the structural door function and simultaneously houses the control element for the variable light transmission functional element. This multi-functionality reduces the number of separate components and simplifies the overall system installation
2Loss of time
If control elements are integrated into the door leaf, then installation effort is minimized, but the door structure becomes more complex
Solution Approach 1:
The control element is pre-integrated into the door leaf during manufacturing rather than being installed separately on-site. This preliminary action reduces installation time at the construction site while the increased structural complexity is managed during the controlled manufacturing process
3Ease of operation
If control elements are accommodated in building walls or distribution cabinets, then the control function is achieved, but significant interventions in existing building structure are required
Solution Approach 1:
The control element is extracted from the building structure (walls, distribution cabinets, suspended ceilings) and relocated to the door leaf. This extraction eliminates the need for building structure interventions while maintaining control accessibility through the door-mounted control element
