Motor Vehicle Seat Storage Pocket with Reinforcement Profile
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle seat storage pockets either deform permanently when storing bulky objects or appear unsightly due to elastic edges, and they occupy unnecessary space when empty, reducing knee room for rear passengers.
Innovation Solution
A motor vehicle seat with a storage pocket featuring a reinforcing profile matching the seat wall shape and an elastic strap that presses the pocket against the wall when empty, providing a robust and aesthetic design that allows wide opening and easy storage without deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the pocket opening edge is made elastic to prevent deformation, then the pocket can accommodate bulky items, but the elastic edge creates visible creases that appear unsightly
Solution Approach 1:
The opening edge is segmented into two distinct functional layers: a reinforcement profile (blade) that provides structural stability and prevents deformation, and an elastic strap that provides flexibility and elastic recovery. This segmentation allows each component to perform its specialized function without the drawbacks of a unified elastic edge.
Solution Approach 2:
The opening edge combines two different materials with complementary properties: a rigid reinforcement profile (blade) made of stiff material for structural support, and an elastic strap material for flexibility and recovery. This composite structure achieves both shape stability and aesthetic appearance by hiding the rigid blade behind the elastic strap.
2Volume of moving object
If the pocket is made completely flat when empty to minimize space occupation, then knee room for rear passengers is improved, but the pocket lacks structural support to withstand stored items
Solution Approach 1:
The pocket structure is segmented into a flat pocket body for minimal space occupation and a reinforcement profile integrated into the opening edge for structural strength. The reinforcement profile is positioned to provide support only where needed (at the opening edge) while keeping the rest of the pocket flat against the seat back.
Solution Approach 2:
The reinforcement profile provides localized structural strength at the opening edge where it is most needed to withstand stored items, while the rest of the pocket remains flat and minimal. This local reinforcement allows the pocket to be flat when empty but strong when items are stored.
3Ease of operation
If the opening edge is made rigid to provide robust appearance and wide opening, then ease of operation is improved, but the pocket occupies more space when empty
Solution Approach 1:
The opening edge is segmented into a rigid reinforcement profile that provides the wide opening and robust appearance, and an elastic strap that allows the edge to flex open easily and then return to a flat position. This segmentation enables easy operation without permanent space occupation.
Solution Approach 2:
The opening edge transitions from a static rigid structure to a dynamic system where the elastic strap allows the edge to flex and move during opening/closing operations, then return to its original flat position. This dynamic behavior provides ease of operation while maintaining minimal space occupation when empty.
