Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exterior and interior doors for residential or commercial buildings face challenges in integrating electric devices due to separate battery-powered operation, which affects structural integrity, insulation, acoustic performance, and aesthetics, with limited integration of power systems and controllers in residential doors.
Innovation Solution
A door system with an AC/DC converter and power management controller that integrates DC electric devices into the door frame, using a central power supply and power distribution system, minimizing battery reliance and ensuring aesthetic and functional integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate battery-powered electric devices are mounted to the door, then the door can provide electronic access control and other functions, but the structural integrity, insulation, and acoustic performance of the door are adversely impacted
Solution Approach 1:
The patent combines multiple separate battery-powered electric devices into a single integrated power system mounted within the door frame. The housing contains both AC and DC power sources along with conversion circuitry, merging what were previously separate components into one unified structure that maintains door integrity while providing all necessary electronic functions.
Solution Approach 2:
The integrated power system performs multiple functions: it provides AC power for high-power devices, DC power for low-power devices, houses battery backups, contains conversion circuitry, and provides mounting for various electric devices. This multi-functional housing replaces what were previously separate battery packs and power supplies for each individual device.
2Adaptability or versatility

3Adaptability or versatility
If separate battery-powered electric devices are mounted to the door, then the door can provide electronic access control and other functions, but battery replacement maintenance is required periodically
Solution Approach 1:
The patent combines multiple separate battery-powered electric devices into a single integrated power system mounted within the door frame. The housing contains both AC and DC power sources along with conversion circuitry, merging what were previously separate components into one unified structure that maintains door integrity while providing all necessary electronic functions.
Solution Approach 2:
The system automatically manages power between AC and DC sources without user intervention. The controller monitors power availability and automatically switches between AC power, DC battery power, and rechargeable battery power, eliminating the need for users to manually replace or recharge batteries.
4Ease of operation
If power systems are integrated into the door, then electric devices can be powered from a central supply, but the complexity of the door system increases
Solution Approach 1:
The controller acts as an intermediary that automatically manages the complex power conversion and distribution tasks. It monitors the AC power input, manages the DC-to-AC converter, controls the rechargeable battery charging/discharging, and switches power sources as needed, shielding users from the underlying complexity while providing simplified operation.

AI summary
A door system comprises a door frame adapted to be mounted within an opening, a door pivotally attached to the door frame, an AC/DC converter operably associated with the door frame, a DC electric device mounted to the door, at least one sensor mounted to the door frame or the door, and a power management controller configured to receive an input from the at least one sensor and send a command to the DC electric device. The AC/DC converter is configured to be electrically connected to an AC power unit disposed outside the door system. The DC electric device is electrically connected to the AC/DC converter.
