Structure and method for attaching load detecting device and sheet device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing load detection device mounting structure cannot adjust the pitch distance between detecting portions, limiting its adaptability to different seat apparatuses and resulting in increased costs due to the need for specialized recessed portions.
Innovation Solution
A mounting structure that includes a recessed portion on the cushion member, where detecting portions are disposed on both sides of the recessed groove, allowing the connecting portion to be placed within it to adjust the pitch distance, utilizing existing grooves as decorative or suspending grooves to avoid additional costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the connecting portion is disposed on an inclined portion to prevent sharp bending, then the connecting portion is protected from damage, but the pitch distance between detecting portions cannot be adjusted
Solution Approach 1:
The connecting portion is designed to be movable within the recessed portion, allowing it to be positioned at different locations to adjust the pitch distance between detecting portions. This dynamic positioning capability enables the same sensor to adapt to different seat apparatuses while the recessed portion provides protection when the connecting portion is positioned appropriately.
2Adaptability or versatility
If specialized recessed portions are added to enable pitch distance adjustment, then adaptability is improved, but manufacturing complexity and costs increase
Solution Approach 1:
The recessed portion serves multiple functions: it protects the connecting portion from damage and simultaneously enables pitch distance adjustment by providing a space where the connecting portion can be positioned at different locations. This multi-functionality eliminates the need for additional specialized structures, maintaining manufacturing simplicity while achieving adaptability.
3Adaptability or versatility
If detecting portions are disposed on both sides of the recessed portion, then pitch distance adjustment is enabled, but the mounting structure becomes more complex
Solution Approach 1:
The mounting structure is segmented into distinct functional areas: the recessed portion for connecting portion placement and protection, and detecting portion disposing portions on both sides for sensing. This segmentation allows each component to perform its specific function independently while working together as a unified system, achieving adjustability without excessive complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the load detection device to be adaptable to various seat apparatuses by adjusting the pitch distance, reducing costs and ensuring detection sensitivity while preventing uncomfortable seating feelings.
Implementation Method 1
only the back surface of the connecting portions is adhered to the recessed portion by means of the double-sided adhesive tape

AI summary
In a mounting structure of mounting a load detection device, the pitch distance between the detecting portions is adjustable by utilizing a recessed portion formed in a member on which the load detection device is mounted so as to accelerate the common use of the load detection device, which can lead to a cost reduction. The load detection device is mounted on the cushion member in such a manner that the respective detecting portions are disposed on the respective detecting portion disposing portions, the one or more connecting portions are disposed on the connecting portion disposing portions, respectively, and the third connecting portion crossing over the groove portion is disposed in the groove portion. Accordingly, the detecting portions are disposed on both sides of the groove portion, that is, the detecting portions are disposed putting the groove portion therebetween. Thus, the pitch distance between the detecting portions is adjustable by utilizing a groove portion, that is, by disposing the third connecting portion in the groove portion.
