Saddle Seat Base with Concave Surface to Restrict Lateral Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing saddle seats, including those like Humantool, fail to provide sufficient movement and stability on soft supports, leading to reduced effectiveness in alleviating sedentary work-related ailments and potentially causing safety issues due to excessive lateral movement.
Innovation Solution
A seat base with a concave surface coated in a softer material, such as woven felt, that guides the round lower part of the saddle seat to its center, enhancing mobility and safety by restricting lateral movement and increasing rolling resistance, thereby improving the operating characteristics of the saddle seat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the saddle seat is placed on a soft support, then comfort is improved, but mobility and stability are reduced
Solution Approach 1:
The patent introduces a seat base as an intermediary component between the saddle seat and the soft support. This seat base provides a stable platform that maintains the saddle seat's mobility and stability while allowing it to be used on soft supports. The seat base acts as a mediator that resolves the conflict between comfort (soft support) and reliability (stability).
Solution Approach 2:
The system is divided into separate components: the saddle seat, the seat base, and the support surface. By segmenting the system, the seat base can be specifically designed to provide stability while the saddle seat maintains its comfort properties, and the soft support provides cushioning. This segmentation allows each component to optimize its function without compromising the others.
2Reliability
If the saddle seat is placed on an even support, then stability is improved, but lateral movement is excessive causing inconvenience and safety issues
Solution Approach 1:
The seat base features an asymmetric concave surface that is symmetric in shape but asymmetric in function - it restricts lateral movement while allowing forward and backward movement. The concave geometry creates natural boundaries that prevent excessive lateral displacement while maintaining stability. This asymmetric constraint approach resolves the contradiction between stability and harmful lateral movement.
3Strength
If the concave surface is coated with harder material, then durability is improved, but mobility of the saddle seat is reduced
Solution Approach 1:
The seat base employs local quality differentiation by using a softer material specifically for the concave surface that contacts the saddle seat, while other parts of the seat base can use harder materials for structural strength and durability. This localized soft coating on the concave surface maintains durability through proper material selection while preserving the mobility needed for the saddle seat to move freely within the concave constraints.

Function Achieved in This Case
The seat base increases the mobility and safety of the saddle seat on soft supports, ensuring it remains centered and stable, allowing for controlled movements that enhance comfort and reduce the risk of accidents, while also improving the overall effectiveness in reducing sedentary work-related discomfort.

AI summary
The present invention relates to a seat base for a saddle seat, the seat base (100) comprising a first face (102), the first face forming a planar surface to allow the seat base to be arranged on a surface to be seated, and a second face (104), the second face forming a concave surface, the concave surface restricting the lateral movement of the saddle seat by guiding the round lower part of the saddle seat towards the lowest point of the concave surface.
