Load support apparatus for lumbar support assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lumbar support apparatuses for vehicles require a large number of components, which increases weight and reduces fuel efficiency while maintaining durability and bearing power, necessitating a design that minimizes components while maintaining performance.
Innovation Solution
A load support apparatus with reinforcing ribs on its lateral and front surfaces, featuring a main support unit with a plate-shaped main plate, concave portions, and rib portions, along with an assembly wire unit and auxiliary support unit, which reduces weight while maintaining bearing power and comfortably supporting the occupant's back.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the number of components is reduced to decrease weight and improve fuel efficiency, then weight and fuel efficiency are improved, but bearing power and durability may be compromised
Solution Approach 1:
The patent combines multiple structural elements (main plate, reinforcing ribs, concave portions) into a single integrated lumbar support apparatus, eliminating the need for separate components while maintaining structural integrity and bearing power through the unified design
Solution Approach 2:
The patent applies local quality enhancement by adding reinforcing ribs specifically at critical stress points and creating concave portions at targeted locations on the main plate, providing localized strength enhancement without increasing overall weight or component count
2Strength
If reinforcing ribs are added to maintain bearing power with fewer components, then bearing power is maintained, but structural complexity increases
Solution Approach 1:
The patent segments the reinforcing structure into distinct rib portions and concave portions that are integrated into the main plate, allowing each element to perform its specific structural function while maintaining overall simplicity through integration rather than separate components
3Use of energy by moving object
If components are minimized to improve fuel efficiency, then fuel efficiency is improved, but manufacturing precision requirements may increase
Solution Approach 1:
The patent merges multiple functions into a single main plate structure with integrated reinforcing ribs and concave portions, reducing the total number of components that need to be manufactured and assembled, thereby improving fuel efficiency while managing manufacturing precision requirements through integration

AI summary
A load support apparatus for a lumbar support assembly is proposed, in which reinforcing ribs are arranged on a lateral surface and a front surface of a concave portion, the load support apparatus maintaining bearing power for supporting an occupant and having a reduced weight. The load support apparatus includes a main support unit including a main plate formed in the shape of a plate, a concave portion formed by one portion of the main plate protruding backward, with a groove being formed in front of the concave portion, and a rib portion formed by protruding from the main plate toward the groove or backward from the main plate.
