There is a need for a solution that enables effortless control of at least one building entity, such as elevators and lighting, in residential and commercial buildings, particularly in high-rise structures where manual operation can be cumbersome.
Innovation Solution
A door handle accessory equipped with a memory, transceiver, sensors (such as acceleration and pressure sensors), and a control unit that communicates with a building system to control entities like elevators and lighting based on user interactions with the door handle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation of building entities (elevator calling, lights switching) is used, then device complexity is reduced, but ease of operation deteriorates due to cumbersome manual control
Solution Approach 1:
The door handle accessory automatically detects user actions (pulling, pushing, pressing) and autonomously triggers building entity operations without requiring manual intervention. The sensor detects door handle interactions and the control unit automatically generates and transmits control signals to the building system, enabling the system to serve itself.
Solution Approach 2:
The patent replaces manual mechanical operation with an automated electromechanical system. Sensors detect mechanical actions on the door handle and convert them into electronic signals that automatically control building entities, substituting the need for manual mechanical control interfaces.
2Ease of operation
If automatic control of building entities is implemented, then ease of operation is improved, but device complexity increases due to additional sensors and control units
Solution Approach 1:
The door handle accessory is designed as a multi-functional device that combines door handle functionality with sensor detection and automatic control capabilities. The same device that serves as a door handle also functions as a sensor platform and control interface, eliminating the need for separate control devices.
Solution Approach 2:
The patent merges the door handle with sensor elements and control electronics into a single integrated accessory. The sensor, control unit, transceiver, and memory are combined within the door handle accessory housing, creating a unified device that performs both mechanical and electronic functions.
3Loss of time
If manual control of building entities is used, then device complexity is low, but loss of time increases due to manual operations required
Solution Approach 1:
The system performs preliminary detection of user intent through sensor monitoring of door handle interactions. By detecting the pull, push, or press action before the user actually needs the building entity operation, the system prepares and executes control actions in advance, reducing the time loss associated with manual operations.
4Extent of automation
If sensors and transceivers are added to the door handle accessory, then extent of automation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The door handle accessory is designed as a modular assembly with distinct functional components (sensor module, control unit, transceiver, memory) that can be manufactured separately and then assembled. This segmentation allows each component to be manufactured with standard precision requirements and simplifies the overall manufacturing process.
