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

VSEngineering 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

Engineering Contradiction:
Improveconnecting portion protectionVSAvoidpitch distance adjustability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

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.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If specialized recessed portions are added to enable pitch distance adjustment, then adaptability is improved, but manufacturing complexity and costs increase

Engineering Contradiction:
Improvepitch distance adjustabilityVSAvoidmounting structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

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

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

Engineering Contradiction:
Improvepitch distance adjustabilityVSAvoidmounting structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #1Segmentation

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.
