Adjustable seat cushion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prolonged sitting leads to continuous pressure on the backside and lower spine, causing soreness and pain, particularly for cyclists and motorcyclists, due to the lack of a comfortable and dynamic seating solution that effectively relieves discomfort.
Innovation Solution
An adjustable seat cushion with a frame that alternates dynamic and static supports, where a rotatable handle adjusts the positioning of dynamic supports relative to static supports, providing customizable comfort by elevating or depressing them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a fixed seating surface is used, then the structure is simple and stable, but continuous pressure is applied to the backside and lower spine causing soreness and pain
Solution Approach 1:
The seat cushion is divided into multiple independent support elements (30-50 supports) that can move relative to each other. Each support is a separate component that can be adjusted independently, allowing the seating surface to segment and adapt to pressure points, thereby relieving continuous pressure on the backside and lower spine.
Solution Approach 2:
The support elements are made movable through a ratchet mechanism that allows each support to be adjusted to different positions. This dynamic capability enables the seat cushion to adapt to the user's body contours and pressure distribution, converting a static structure into a dynamic one that can respond to and relieve pressure points.
2Ease of operation
If multiple adjustable supports are added to relieve pressure, then comfort is improved, but the device complexity increases
Solution Approach 1:
The ratchet mechanism is designed to be manually operated by the user without requiring external assistance or complex controls. Each support element can be independently adjusted by the user through simple manual manipulation, allowing the system to serve itself and the user without adding complex automation or control systems.
Solution Approach 2:
The adjustment mechanism allows each support element to change its position parameter independently, enabling the user to modify the firmness and contour of the seating surface by adjusting the height or angle of individual supports. This parameter change capability provides customizable comfort without requiring a completely complex system.
3Object-affected harmful factors
If the seating surface is made dynamic and adjustable, then pressure relief and comfort are improved, but the stability of the seat structure is reduced
Solution Approach 1:
The ratchet mechanism is pre-configured to lock each support element in place once adjusted, providing immediate stability. The preliminary locking action ensures that once the user adjusts a support to the desired position, it remains fixed and stable, preventing unintended movement during use while maintaining the overall dynamic adjustability of the system.

AI summary
An adjustable seat cushion. The adjustable seat cushion provides a frame defining an interface. The interface receives a plurality of dynamic supports and a plurality of static supports. The plurality of dynamic supports is disposed alternatingly between the plurality of static supports upon the interface. A handle is in operable connection with the plurality of dynamic supports. Rotation of the handle in a first direction elevates the plurality of dynamic supports relative to the plurality of static supports. Rotation of the handle in a second direction depresses the plurality of dynamic supports relative to the plurality of static supports.
