Solution Overview

Problem

Existing learning-to-sit chairs, especially those with foam or fabric materials, are not suitable for bathing due to water accumulation and are unsafe for infants as they can slide or fall off during use due to instability.

Innovation Solution

A learning-to-sit chair design featuring a base with a cushion recess, a backrest structure, and a legrest portion, along with anti-slipping grooves and inflatable components, which provides position limiting and increased friction to prevent sliding and falling, and includes an anti-slipping silicone rubber sheet for enhanced stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If foam material, leather or plush fabric is used for the chair surface, then comfort is improved, but water accumulation occurs and drying becomes difficult

Engineering Contradiction:

ImprovecomfortVSAvoidwater resistance

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent changes the material parameter from absorbent materials (foam, leather, plush fabric) to non-absorbent smooth material (plastic), which prevents water accumulation and enables easy drying while maintaining comfort through the cushioned design

Inventive Principle:

Principle #35Parameter changes

2Ease of manufacture

If the chair surface is made smooth for easy cleaning, then ease of maintenance is improved, but friction decreases causing infants to slide and fall

Engineering Contradiction:

Improveease of cleaningVSAvoidsafety

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent applies different surface qualities to different parts: the seat surface remains smooth for easy cleaning, while the backrest and side surfaces incorporate anti-slip grooves to increase friction and prevent sliding, thus maintaining both ease of cleaning and safety

Inventive Principle:

Principle #3Local quality

3Ease of manufacture

If the base is made circular or square with flat surface, then manufacturing is simplified, but infants cannot maintain stable sitting position

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidsitting stability

Core Design Contradiction:

Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The patent segments the base surface into different functional zones: a cushion recess area for stable buttock positioning, and a legrest portion with anti-slip grooves for leg support, creating multiple contact points that enhance sitting stability

Inventive Principle:

Principle #1Segmentation

4Device complexity

If the chair structure is simplified, then device complexity is reduced, but ability to prevent sliding and falling decreases

Engineering Contradiction:

Improvestructural complexityVSAvoidanti-slip performance

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent adds anti-slip grooves only to specific locations (backrest and side surfaces) rather than the entire chair, providing enhanced friction where needed while keeping the overall structure simple and maintaining ease of manufacturing

Inventive Principle:

Principle #3Local quality
