Seat Base Stabilizer Tabs Prevent Slider Binding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Movable seating assembly components tend to experience 'binding' or 'chuck' laterally or perpendicularly during adjustments, leading to inoperability, component damage, and reduced operation speed, causing customer dissatisfaction.
Innovation Solution
The implementation of stabilizer tabs integrated into the thigh-extension slider, which provide a transverse tension force along the X-, Y-, and Z-axes to maintain the thigh-extension slider on its centerline of travel, preventing lateral or perpendicular motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If movable seating assembly components are adjusted forward, back, up, down, out, in, and/or rotated, then the seating assembly provides positional flexibility and adaptability, but binding or chuck occurs laterally or perpendicularly to the direction of travel causing inoperability, component damage, and reduced operation speed
Solution Approach 1:
The patent introduces stabilizer tabs as intermediary elements between the movable seating components and the guide tracks. These tabs act as mediators that enforce proper alignment and prevent lateral deviations that cause binding. The stabilizer tabs engage with corresponding features in the guide tracks to maintain correct positional relationships during movement, thereby preventing binding while preserving adaptability.
Solution Approach 2:
The patent implements alignment features and guide structures that pre-establish the correct path of movement before the actual adjustment occurs. The stabilizer tabs are positioned and configured in advance to guide the movement along the intended trajectory, preventing lateral deviations before they can cause binding or damage.
2Reliability
If stabilizer tabs are integrated into the thigh-extension slider, then lateral or perpendicular undesired motion is prevented, but device complexity increases
Solution Approach 1:
The patent merges the stabilizer tabs with the thigh-extension slider by integrating them as unified components. Rather than adding separate, independent stabilizing mechanisms, the tabs are formed as part of the slider assembly itself, reducing the number of discrete parts while maintaining the binding-prevention function.
Solution Approach 2:
The patent divides the stabilizing function into multiple discrete tabs rather than using a single complex stabilizing structure. Each tab handles specific aspects of alignment and prevention, allowing for modular design and easier manufacturing while achieving comprehensive binding prevention.
