Vehicle Seat Mono-Post Structure for Durable Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional height adjustment devices in vehicle seats often fail to adequately accommodate various passenger postures and suffer from durability issues due to the deterioration of link mechanisms.
Innovation Solution
A vehicle seat with a simplified mono-post structure featuring a height adjusting mono-post module, comprising an upper and lower end base connected by connection brackets and an angle adjuster system, which allows for stable and durable height adjustment through a synchronized rotation mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional link mechanism is used for height adjustment, then the device can adjust seat height, but the durability deteriorates due to link wear and mechanical failure
Solution Approach 1:
The patent extracts and eliminates the complex link mechanism from the height adjustment device, replacing it with a direct mono-post structure that achieves height adjustment through a single vertical post with integrated adjustment components, thereby removing the wear-prone link elements
Solution Approach 2:
The patent changes the structural parameters from a multi-component link mechanism to a simplified mono-post configuration, altering the fundamental architecture to improve durability while maintaining height adjustment functionality
2Adaptability or versatility
If a conventional height adjustment device is used, then basic height change is possible, but the height adjustment angle is insufficient and cannot accommodate various passenger postures
Solution Approach 1:
The patent implements a dynamic height adjustment mechanism that allows the mono-post to rotate and adjust to multiple angles, enabling the seat to adapt to various passenger postures and positions rather than being fixed at a single height
3Reliability
If a simplified mono-post structure is implemented, then durability and stability improve, but the device complexity increases due to additional components like angle adjusters
Solution Approach 1:
The patent merges the height adjustment function and angle adjustment function into a single integrated mono-post structure, combining multiple functions in one unified component rather than using separate mechanisms, which improves stability while managing complexity
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 enhanced stability, durability, and collision strength while minimizing seat gaps and movements, thereby improving operation sensibility and marketability.
Implementation Method 1
a connection bracket that connects the upper end base and the lower end base to each other and is configured to rotate relative to the lower end base, where the upper end base is configured to move relative to the lower end base based on a rotation of the connection bracket
