Door control system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals with temporary or permanent physical disabilities face challenges in opening and closing doors due to the need for applying force to overcome locking mechanisms, which existing solutions do not adequately address.
Innovation Solution
A door control system comprising a baseplate, door rams, actuators, a biasing device, and a controller that can be removably fastened to a surface, allowing for automated opening and closing of doors through pneumatic or electromechanical actuation, and integration with smart devices for remote or voice-activated control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual force is applied to open or close a door, then the door can be opened or closed, but users with physical disabilities cannot provide the required force
Solution Approach 1:
The patent replaces the manual mechanical system with an automated electromechanical system. A controller receives signals from smart devices and automatically actuates the door by controlling a motorized mechanism, eliminating the need for users to physically apply force to overcome locking mechanisms or negative pressure.
Solution Approach 2:
The door system performs self-service by automatically opening and closing without human physical intervention. The controller autonomously manages the door actuation process based on received commands, and the system includes self-monitoring capabilities through indicators that display operational status without requiring user interpretation of mechanical states.
2Ease of operation
If automated door control system is implemented, then ease of operation for disabled users is improved, but device complexity increases
Solution Approach 1:
The controller serves multiple functions: receiving signals from various smart devices (smartphone, tablet, computer), processing different command types (open, close, stop), controlling the motorized actuation mechanism, and managing the indicator system. This multi-functionality consolidates what could be separate complex components into a single integrated unit.
Solution Approach 2:
The patent introduces a wireless communication intermediary layer between the user's smart device and the door control system. The controller acts as a mediator that receives digital signals, translates them into mechanical actuation commands, and provides feedback through indicators, simplifying the interface between the user and the mechanical door system.
3Ease of manufacture
If removable fastening is used for baseplate, then ease of installation and relocation is improved, but reliability of attachment may be reduced
Solution Approach 1:
The baseplate attachment system transitions from a static permanent installation to a dynamic removable design. The baseplate can be installed, removed, and reinstalled at different locations while maintaining reliable attachment during use. This dynamic capability allows the system to adapt to different installation environments and user needs without compromising operational reliability.
