Variable Light Transmission Panels for Entryway Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing building entryway systems, including doors and windows, rely on battery-powered electronic devices, which can lead to inconvenience and inefficiency due to battery depletion and the need for frequent replacement, especially in systems requiring variable light transmission panels (VLTPs) that demand external electrical wiring and certified electrical technicians for installation and maintenance.
Innovation Solution
Integration of VLTPs within building entryway systems that utilize the building's main power supply, eliminating the reliance on primary batteries and allowing for self-sufficient installation and maintenance by incorporating control electronics and power modulators, enabling connection to the building's electrical system without the need for certified technicians, and using rechargeable batteries or solar cells for power supplementation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If battery-powered electronic devices are used in building entryway systems, then installation is simpler without external wiring, but batteries require frequent replacement and maintenance
Solution Approach 1:
The system uses the building's existing electrical infrastructure to power the VLTP, eliminating the need for battery replacement. The door system integrates with the building's electrical system through the electrical connection component, allowing the VLTP to operate continuously without manual intervention for power source replacement.
Solution Approach 2:
The electrical connection component serves multiple functions: it provides electrical power to the VLTP, establishes communication between the door system and building management systems, and enables integration with existing building infrastructure. This multi-functionality eliminates the need for separate battery systems.
2Reliability
If external electrical wiring is implemented for VLTPs, then continuous power supply is achieved, but installation requires certified electrical technicians
Solution Approach 1:
The electrical connection component acts as an intermediary that bridges the VLTP and the building's electrical system. It provides standardized connection interfaces that simplify installation while ensuring safe integration with the building's electrical infrastructure, reducing the need for complex wiring work by certified technicians.
Solution Approach 2:
The electrical connection component is pre-integrated into the door system during manufacturing, with connection terminals and wiring harnesses prepared in advance. This preliminary preparation allows for simpler on-site installation by reducing the amount of electrical work required during the installation process.
3Duration of action of moving object
If rechargeable batteries are used for power supplementation, then extended operation is achieved, but device complexity increases
Solution Approach 1:
The system dynamically manages power by changing operational parameters based on available power reserves. When main electrical power is unavailable, the system transitions to battery power mode, adjusting the VLTP's operation to extend battery life. This parameter-based power management provides extended operation without requiring complex dual-power system architecture.
