Problem

Existing devices for monitoring the position of window or door handles and their locking states require numerous sensors, making them complex and difficult to retrofit, and often necessitate replacing the entire handle to adapt to different environmental conditions.

Innovation Solution

A device with a printed circuit board arranged within the olive housing, connected to a connecting device in a rotationally secure manner, utilizing a 3D sensor to autonomously determine its position and the handle's position, allowing for simplified monitoring of both the handle and window or door positions, with modular design for adaptability and reduced sensor complexity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple sensors are used to monitor handle position and window/door position, then monitoring capability is improved, but device complexity increases

Engineering Contradiction:
Improvemonitoring capabilityVSAvoidsensor quantity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple sensing functions into a single sensor device. The sensor device integrates both handle position detection and window/door position detection capabilities, eliminating the need for separate sensors for each function. This merging approach maintains comprehensive monitoring capability while significantly reducing device complexity and sensor quantity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The sensor device is designed with multi-functionality to perform multiple monitoring tasks simultaneously. It can detect handle position, window position, door position, and locking state using the same sensor unit, making the system more efficient and less complex while maintaining reliable monitoring across all parameters.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If the entire handle is replaced to adapt to different environmental conditions, then adaptability is improved, but ease of manufacture deteriorates

Engineering Contradiction:
Improveadaptation to environmental conditionsVSAvoidhandling complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The system is divided into modular components: a standardized handle unit and a configurable sensor device. The sensor device can be independently selected and adapted to different environmental conditions without replacing the entire handle. This segmentation allows for easier manufacturing and assembly while maintaining adaptability to various applications.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system allows dynamic configuration where the sensor device can be adapted to different environmental conditions through software or modular hardware additions rather than physical handle replacement. This dynamic approach enables flexibility in adapting to different conditions while keeping the manufacturing process simple and standardized.

Inventive Principle:
Principle #15Dynamics

3Measurement precision

If numerous sensors and additional manipulations are used for retrofitting, then monitoring accuracy is improved, but ease of operation deteriorates

Engineering Contradiction:
