Actuation Handle Access Control with Gesture Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door and window handles require manual manipulation to unlock and open doors, which can be cumbersome, especially when using electromechanical locks that require a key or transponder identification.
Innovation Solution
An actuation handle with an integrated access control system that includes a reader for transponder identification and a sensor for detecting gestures, allowing for hands-free or foot-operated door opening by activating a motorized lock after a transponder is recognized.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electromechanical door locks are used with key or transponder identification, then security is improved, but the manipulation effort and complexity of operation increase
Solution Approach 1:
The patent replaces manual mechanical handle manipulation with an automated sensor-based detection system. The sensor detects the user's approach and the system automatically activates the motorized lock mechanism, eliminating the need for manual key insertion or handle turning while maintaining secure access control through transponder identification.
Solution Approach 2:
The door opening system performs the unlocking action automatically upon detecting the authorized transponder and user approach. The system serves itself by self-activating the motorized lock without requiring manual intervention, thus reducing manipulation effort while maintaining security protocols.
2Device complexity
If manual handle manipulation is required for door opening, then device simplicity is maintained, but accessibility and convenience deteriorate
Solution Approach 1:
The patent substitutes manual mechanical handle operation with an automated sensor-actuated system. The sensor detects user approach and triggers the motorized lock mechanism automatically, eliminating the need for manual handle manipulation and thereby improving accessibility for users with mobility limitations while maintaining relatively simple device architecture.
3Ease of operation
If transponder identification is integrated with motorized lock actuation, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent merges the transponder reader, sensor detection system, evaluation unit, and motorized lock actuator into an integrated access control system. This consolidation combines multiple functions into a single coordinated mechanism, improving ease of operation by automating the access sequence while managing device complexity through functional integration rather than separate components.
Solution Approach 2:
The actuation handle serves multiple functions: it acts as a sensor mounting structure, houses the transponder reader, contains the evaluation unit for access control logic, and triggers the motorized lock mechanism. This multi-functionality reduces the need for separate components, thereby improving ease of operation without proportionally increasing overall device complexity.

AI summary
An actuation handle (4) for attaching to an outside of a door (2) has an access control system designed to control a motorized lock, that contains an evaluation unit and a reader (8) for reading and identifying a transponder located in a first detection range (12) defined by the reader (8). The reader (8) is integrated in the actuation handle (4). There is also a sensor (10) for detecting an object located in a second detection range (14) defined by the sensor (10), which is coupled to the evaluation unit and integrated in the actuation handle (4). The sensor (10) is located on a first section (16) of the actuation handle (4), and the second detection range (14) extends outward from the first section (16). The evaluation unit is configured to activate the sensor (10) to detect an object in the second detection range (14) after identifying a transponder.
