Find Innovative SolutionsGenerate Solutions
Solution Overview
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
Engineering 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
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.
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.
2Adaptability or versatility
If the entire handle is replaced to adapt to different environmental conditions, then adaptability is improved, but ease of manufacture deteriorates
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.
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.
3Measurement precision
If numerous sensors and additional manipulations are used for retrofitting, then monitoring accuracy is improved, but ease of operation deteriorates
Solution Approach 1:
The patent merges multiple sensing functions into a single sensor device that can be retrofitted without complex manipulations. The unified sensor device maintains accurate position detection for both handle and window/door while simplifying the retrofitting process by eliminating the need for multiple separate sensor installations and adjustments.
