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

VSEngineering 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

Engineering Contradiction:
ImprovecomfortVSAvoidmobility and stability
Core Design Contradiction:
Ease of operationVSReliability

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).

Inventive Principle:
Principle #24Intermediary (Mediator)

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.

Inventive Principle:
Principle #1Segmentation

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

Engineering Contradiction:
ImprovestabilityVSAvoidexcessive lateral movement
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

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.

Inventive Principle:
Principle #4Asymmetry

3Strength

If the concave surface is coated with harder material, then durability is improved, but mobility of the saddle seat is reduced

Engineering Contradiction:
ImprovedurabilityVSAvoidmobility
Core Design Contradiction:
StrengthVSEase of operation

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.

Inventive Principle:
Principle #3Local quality
