Solution Overview

Problem

Conventional child chairs lack the functionality to convert between a high chair and a bouncing chair, requiring separate chairs for different modes of operation, which is inconvenient for users.

Innovation Solution

A child chair design incorporating a frame, reclining adjusting device, locking device, and bouncing device that allows the seat to pivot and bounce relative to the frame, enabling conversion between high chair and bouncing chair modes through selective locking and release statuses.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a child chair is designed as a conventional high chair with fixed seat position, then the structural stability is improved, but the adaptability is worsened because it cannot convert to bouncing chair mode

Engineering Contradiction:
Improvestructural stabilityVSAvoidconvertibility between high chair and bouncing chair modes
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The seat is designed with a pivot connection to the frame, allowing it to rotate between a first position (high chair mode) and a second position (bouncing chair mode). The reclining adjusting device includes a locking mechanism that can lock the seat at different angular positions, enabling the chair to dynamically adapt between stable high chair configuration and flexible bouncing configuration.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If a child chair is designed with movable seat for bouncing function, then the adaptability is improved, but the structural stability is worsened because the seat may become unstable when not properly locked

Engineering Contradiction:
Improveconvertibility between high chair and bouncing chair modesVSAvoidstructural stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The reclining adjusting device incorporates a locking mechanism with locking and release statuses. When locked, the seat is securely fixed at desired angles providing stability. When released, the seat can move freely enabling bouncing function. This dynamic locking system ensures structural stability is maintained when needed while allowing mobility when required.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If separate chairs are purchased for high chair and bouncing chair functions, then the functional versatility is improved, but the device complexity and cost are worsened

Engineering Contradiction:
Improvemulti-functionalityVSAvoidnumber of chairs required
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The child chair is designed as a universal multi-functional device that can operate in both high chair mode and bouncing chair mode. The frame, seat, and reclining adjusting device work together to provide both functions, eliminating the need for separate chairs and reducing overall device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines the functions of high chair and bouncing chair into a single integrated device. The frame structure supports both functions, the pivot connection enables mode switching, and the reclining adjusting device with locking mechanism provides both stable positioning and flexible movement, merging what were previously separate products into one unified chair.

Inventive Principle:
Principle #5Merging (Combining)

4Adaptability or versatility

If the reclining adjusting device allows free movement for bouncing, then the bouncing function is improved, but the ease of operation is worsened because users must manage locking and release mechanisms

Engineering Contradiction:
Improvebouncing functionVSAvoidoperation complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The reclining adjusting device features a locking mechanism that can be locked or released to control seat movement. When released, the seat moves freely enabling bouncing. The dynamic nature of this mechanism allows simple transition between modes while maintaining ease of operation through intuitive locking and releasing actions.

Inventive Principle:
Principle #15Dynamics
