Integrated Sensor in Mechatronic Control Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern motor vehicle air conditioning systems have outwardly visible internal temperature sensors that detract from the design aesthetics due to visible joints, material differences, and misalignment, making them undesirable from a design perspective.
Innovation Solution
Integrating the temperature sensor into a mechatronic control element, such as a rotary control or button, within the vehicle's audio control panel, where it serves as both a functional and design component, using a cap that is materially bonded or form-fitting to protect the sensor and provide an aesthetically appealing surface, while allowing for efficient space use and reliable measurement transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the temperature sensor is arranged as a separate component with an outwardly visible cap, then the sensor can be easily installed and accessed, but the visible joints and material differences detract from the design aesthetics
Solution Approach 1:
The patent combines the temperature sensor with the climate control element into a single integrated unit. The sensor is built directly into the control element housing, eliminating the need for a separate visible cap and reducing the number of external joints and material transitions, thereby improving design aesthetics while maintaining installation ease
Solution Approach 2:
The climate control element serves dual functions: it acts as both the user interface for climate control and houses the temperature sensor. This multi-functionality eliminates the need for a separate sensor component, reducing visual clutter and improving overall design integration
2Shape
If the sensor is integrated into the control element, then design aesthetics are improved and installation space is reduced, but the sensor may be more difficult to access for maintenance
Solution Approach 1:
The patent designs the climate control element as a modular assembly where the sensor can be accessed by disassembling the control element into separate components. This segmentation allows the sensor to be integrated for aesthetic purposes while maintaining accessibility for maintenance through controlled disassembly
3Ease of operation
If the sensor is placed in an exposed position, then it can be easily accessed, but it may be subject to masking or influencing of sensor values
Solution Approach 1:
The patent positions the temperature sensor within the climate control element housing, which acts as an intermediary structure. This location protects the sensor from direct environmental influences and masking while maintaining its ability to accurately measure ambient temperature through the housing material
