Solution Overview

Problem

Child chairs lack detachability between the seat and supporting frame, leading to space inefficiency and safety hazards due to unsecured straps when not in use.

Innovation Solution

A child chair design featuring a detachable supporting frame and integrated strap storage system, allowing the chair to convert between high chair and booster configurations while ensuring strap safety by covering and uncovering storage compartments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the supporting frame is made detachable from the seat, then space efficiency is improved, but the structural complexity increases

Engineering Contradiction:

Improvestorage spaceVSAvoiddetachable coupling structure

Core Design Contradiction:

Volume of moving objectVSDevice complexity

Solution Approach 1:

The child chair is divided into separable components: a seat and a supporting frame. The coupling section allows these components to be detachably connected, enabling the frame to be removed for compact storage while maintaining structural integrity during use.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The coupling section serves multiple functions: it provides a detachable connection between the seat and frame, incorporates strap storage compartments, and includes covering members that serve both as protective covers and as indicators of the chair's configuration state.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If straps are stored externally on the chair, then ease of access is improved, but safety hazards increase due to exposed straps

Engineering Contradiction:

Improvestrap accessibilityVSAvoidstrangling hazard

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The straps are nested within storage compartments that are integrated into the coupling section. The covering members enclose these compartments, hiding the straps when not in use and eliminating the strangling hazard while allowing quick access when needed.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The covering members act as intermediaries between the straps and the external environment. They provide a safe enclosure for the straps, preventing direct contact with children while still allowing controlled access when the covering is opened.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If the chair is designed as a single fixed configuration, then structural simplicity is improved, but adaptability decreases

Engineering Contradiction:

Improveconfiguration flexibilityVSAvoiddetachable components

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The chair transitions from a static, fixed configuration to a dynamic system where the supporting frame can be detached and reattached. This allows the chair to adapt between different configurations (with or without frame) based on usage needs, while the coupling mechanism maintains simplicity through standardized interfaces.

Inventive Principle:

Principle #15Dynamics
