Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle seat base assemblies lack sufficient customization options to accommodate users of varying heights and comfort preferences, limiting adaptability and configurability within vehicle cabins.
Innovation Solution
A seat base assembly featuring a dual circular track system with inner and outer rings, upturned seat legs, and a lock assembly, allowing for adjustable and rotatable seating configurations that enhance user comfort and adaptability by increasing the surface area of engagement and providing greater configurability within the vehicle cabin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional seat base assemblies are used, then the structure is simple, but the adaptability and customization options are insufficient
Solution Approach 1:
The seat base assembly is divided into multiple independent components: dual circular track assembly with inner and outer rings, multiple seat legs (front, rear, inner, outer), adjustment tracks, and lock assembly. This segmentation allows each component to be optimized independently while providing multiple adjustment points, thereby increasing adaptability without requiring complete redesign of the entire system.
Solution Approach 2:
The seat base assembly incorporates dynamic adjustment capabilities through the dual circular track system that allows rotational movement and positional adjustment. The lock assembly enables the system to transition between locked (fixed position) and unlocked (adjustable position) states, providing dynamic adaptability while maintaining structural integrity when adjustments are not needed.
2Adaptability or versatility
If the dual circular track assembly with multiple seat legs is implemented, then the configurability and surface area of engagement are increased, but the device complexity increases
Solution Approach 1:
The dual circular track assembly serves multiple functions simultaneously: it provides rotational adjustment, positional adjustment along the circular path, and structural support for multiple seat legs. The inner and outer rings work together to enable both radial and tangential movements, making a single component perform multiple adjustment functions that would otherwise require separate mechanisms.
Solution Approach 2:
The inner ring is nested within the outer ring of the dual circular track assembly. This nested configuration allows the inner ring to provide additional adjustment capabilities within the space defined by the outer ring, maximizing the adjustment range and configurability while minimizing the overall space required for the adjustment mechanism.
3Adaptability or versatility
If conventional horizontal adjustment is provided, then the structure is simple, but the ability to accommodate various user preferences and heights is limited
Solution Approach 1:
The adjustment mechanism transitions from conventional one-dimensional horizontal movement to two-dimensional adjustment along circular paths. The dual circular track assembly enables movement in both radial and tangential directions, allowing users to adjust the seat position in multiple dimensions to accommodate various body types, heights, and comfort preferences, thereby enhancing user accommodation capabilities.
