Conveyance Seat Fixing Member With Reinforced Multi-Hole Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conveyance seats lack an effective configuration for attaching objects, such as luggage, securely and efficiently, especially in the 'tip-up state', due to inadequate design of the fixing member.
Innovation Solution
A fixing member is attached to the back surface of the seat cushion, featuring a first and second attachment portion spaced apart, connected by a reinforcing connecting portion with multiple through holes and hook portions, allowing for secure attachment of objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a simple fixing member is used without reinforcement, then the device complexity is reduced, but the attachment strength and reliability are insufficient for securely holding objects
Solution Approach 1:
The fixing member is segmented into distinct functional portions: first and second attachment portions for securing to the seat cushion, a connecting portion linking them, and multiple through holes for object attachment. This segmentation allows each portion to be optimized for its specific function while maintaining overall structural integrity.
Solution Approach 2:
The fixing member utilizes composite construction combining rigid attachment portions for structural strength with through holes for functional attachment. The connecting portion with integrated through holes creates a composite structure that provides both mechanical strength and attachment functionality without requiring separate components.
2Adaptability or versatility
If multiple attachment portions are provided spaced apart, then the adaptability for attaching objects is improved, but the device complexity increases
Solution Approach 1:
The fixing member is designed with universal applicability through multiple attachment portions spaced apart on the back surface of the seat cushion, allowing various objects to be attached at different positions. The through holes in the connecting portion provide additional universal attachment points, making the fixing member versatile for different object types and attachment needs.
Solution Approach 2:
The fixing member merges multiple functions into a single integrated component: the attachment portions for securing to the seat, the connecting portion for structural linkage, and the through holes for object attachment are all combined in one piece, reducing the need for multiple separate components.
3Ease of operation
If a connecting portion with through holes is added, then the ease of operation for attaching objects is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The through holes are pre-formed in the connecting portion during the fixing member manufacturing process, enabling easy object attachment later without requiring additional drilling or preparation steps. This preliminary action simplifies the operation of attaching objects to the seat cushion.

AI summary
There is provided a fixing member for a conveyance seat, which allows an object to be more suitably attached than in the related art. A fixing member for a conveyance seat is a member attached to a back surface of a seat cushion and used for attaching an object to the conveyance seat. The fixing member includes a first attachment portion and a second attachment portion provided spaced apart from each other along the back surface of the seat cushion, and attached to the back surface of the seat cushion, and a connecting portion connecting the first attachment portion and the second attachment portion. A plurality of through holes for fixing the object are formed in the connecting portion.
