Solution Overview
Problem
Existing detection mechanisms for contact with a contact body, such as those used in vehicle steering wheels, lack extensibility and flexibility, which limits their effectiveness in detecting contact accurately and efficiently.
Innovation Solution
A detection mechanism that includes a conducting body, an insulating body, and a coupling member with protrusions that form through holes, allowing for high extensibility and flexibility by enabling the conducting and insulating bodies to be coupled and extended, while preventing relative tilting and extension limitations at thread intersections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a coupling member is provided between the conducting body and insulating body without through holes, then the structural integrity is maintained, but the extensibility of the detection section is limited
Solution Approach 1:
The coupling member is designed as a thin film structure with through holes, allowing it to be flexible and extensible while maintaining sufficient coupling strength. The thin film nature enables the detection section to expand and adapt to curved surfaces without compromising the structural integrity of the conducting body and insulating body connection.
2Ease of operation
If the detection section is made rigid to maintain structural stability, then manufacturing precision is improved, but ease of installation on curved surfaces deteriorates
Solution Approach 1:
The detection section is segmented into conducting body, insulating body, and coupling member components. This segmentation allows the detection section to be assembled in a controlled manner with precise positioning, while the overall structure remains flexible for installation on curved surfaces like steering wheels.
Solution Approach 2:
The protrusions are pre-formed on the conducting body and insulating body before assembly. This preliminary action ensures that when the components are assembled, the through holes are automatically formed at the correct positions in the coupling member, maintaining manufacturing precision while enabling flexible installation.
3Ease of manufacture
If protrusions are provided on both conducting body and insulating body, then through hole formation is improved, but device complexity increases
Solution Approach 1:
The protrusions on the conducting body and insulating body automatically serve to form the through holes in the coupling member during assembly. This self-service mechanism eliminates the need for separate through hole formation steps, simplifying the manufacturing process while improving through hole formation accuracy.

Function Achieved in This Case
The solution enhances the extensibility and flexibility of the detection mechanism, enabling accurate contact detection and easy assembly onto curved surfaces, thereby improving the detection accuracy and ease of installation.
Implementation Method 1
a coupling member provided at the detection section between the conducting body and the insulating body and solidified so as to couple the conducting body and the insulating body together
Implementation Method 2
a protrusion provided at at least one of the conducting body or the insulating body, the conducting body and the insulating body making contact at an installation position of the protrusion so as to form a through hole in the coupling member

AI summary
A sensor electrode and an insulating body are coupled together by a hot melt member in a sensor of a steering wheel. The sensor electrode makes contact with the insulating body at first protrusions so as to form through holes in the hot melt member. The hot melt member is accordingly able to stretch easily due to the through holes, enabling a high extensibility for the sensor to be achieved.
