Seat Depth Adjustment Trim Member Gap Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seat cushion arrangements for motor vehicle seats are complex, difficult to assemble, and require significant space due to their design, particularly in the seat structure mounting process.
Innovation Solution
A seat depth adjustment device with a trim member connected to both cushion members, featuring an elastic member that is directly or indirectly connected to the guiding member and seat front part, allowing the trim member to be pulled into a gap upon adjustment, facilitated by an attachment member that clips or hooks onto an edge section without requiring tools, enabling a simpler and faster assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bolts are used to connect the elastic member to the seat front part, then the connection is secure, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The connection method is changed from rigid bolt connection to flexible attachment member connection, altering the connection parameters to achieve both security and ease of assembly
Solution Approach 2:
The attachment member is extracted as a separate component that simplifies the connection process, eliminating the need for complex bolt assembly while maintaining connection reliability
2Adaptability or versatility
If a complex seat depth adjustment device design is used, then the functionality is complete, but the assembly process becomes difficult and space requirements increase
Solution Approach 1:
The seat depth adjustment device is segmented into modular components (guiding member, adjustment member, elastic member, trim member) that can be assembled independently and then integrated, reducing overall assembly complexity
Solution Approach 2:
The device uses dynamic elements such as the elastic member that can flex and the trim member that can move between extended and retracted positions, allowing complete functionality with simpler structural requirements
3Ease of manufacture
If the trim member is fully extended to cover the gap, then the aesthetic appearance is improved, but the space requirement increases
Solution Approach 1:
The trim member is designed as a dynamic element that can extend to cover the gap for aesthetic purposes and retract when not needed, allowing the system to adapt its volume based on functional requirements
Solution Approach 2:
The trim member is implemented as a flexible textile or thin film structure that can be extended or retracted, providing aesthetic coverage when needed while minimizing space requirements when retracted
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
The solution provides an improved connection and assembly process for the seat depth adjustment device, resulting in a more compact and efficient design that is less prone to detachment, allowing for easier integration into motor vehicle seats.
Implementation Method 1
an elastic member which is connected to the trim member and to at least one of the guiding member and the seat front part and which is configured to pull the trim member into the gap
