Seat Adjuster Using Fluid Bladder for Adjustable Suspension Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seat adjusters are often complex, difficult to assemble, and may not provide sufficient support for users, leading to inadequate comfort and support in seat assemblies.
Innovation Solution
A seat adjuster comprising a support member and a fluid bladder, where the bladder is positioned between the support member and the suspension portion of the seat frame, allowing for adjustable support by varying the volume of the bladder to provide different levels of support to the suspension portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional mechanical support structures are used, then structural strength is provided, but device complexity increases and ease of manufacture deteriorates
Solution Approach 1:
The patent employs a fluid bladder that can be inflated and deflated to provide adjustable support to the seat suspension portion. By using pneumatic pressure from a fluid source (air or liquid) to create support forces, the system replaces complex mechanical linkages with a simpler elastic support mechanism that can be controlled through fluid pressure regulation
Solution Approach 2:
The support characteristics are adjusted by changing the volume of fluid in the bladder, which modifies the support force and compliance. This allows the same physical structure to provide different levels of support by simply varying the fluid volume parameter, eliminating the need for multiple mechanical adjustment mechanisms
2Ease of manufacture
If fixed support structures are used, then manufacturing simplicity is maintained, but adaptability and comfort deteriorate
Solution Approach 1:
The support system transitions from a static fixed structure to a dynamic adjustable system where the bladder can be inflated to different volumes based on user needs. The fluid bladder provides compliant, adaptable support that can respond to different loading conditions and user preferences while maintaining a simple overall structure that is easy to manufacture
Solution Approach 2:
The fluid bladder serves multiple functions: it provides structural support, acts as a cushioning element, and enables adjustable firmness levels all within a single component. This multi-functionality eliminates the need for separate mechanical adjustment devices, maintaining manufacturing simplicity while achieving adaptability
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 enables adjustable support to the user by inflating the bladders to various levels, limiting deformation of the suspension portion, thereby enhancing comfort and support, making the seat adjuster more user-friendly and effective.
Implementation Method 1
A seat adjuster may include a support member and a fluid bladder. The fluid bladder may be disposed at least partially between the support member and the suspension portion. A change or adjustment of a volume of the fluid bladder may change or adjust the support provided to the suspension portion.
Data Source
AI summary
A seat adjuster may include a support member and a fluid bladder. The support member may have a first end and a second end. The first end and the second end may be connectable to a seat frame such that the support member is disposed at least partially below a suspension portion of said seat frame. The fluid bladder may be disposed at least partially between the support member and said suspension portion. The fluid bladder may be configured to support said suspension portion. A change or adjustment of a volume of the fluid bladder may change or adjust the support provided to said suspension portion.
