Solution Overview

Problem

Existing infant seats lack the ability to adjust the incline of the upper and lower body support surfaces and side restraints, failing to accommodate changing infant needs and provide optimal comfort and safety.

Innovation Solution

An adjustable infant seat assembly with independently adjustable first and second seat portions and lateral containment supports, allowing for various angles and incline adjustments, including a pivot connection and multiple adjustment assemblies for precise positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If infant seats use fixed predetermined angles for seat portions and restraints, then the structure is simple and reliable, but the seat cannot accommodate changing infant needs and provide optimal comfort

Engineering Contradiction:

Improveadjustability of seat portions and restraintsVSAvoidcomplexity of adjustment mechanisms

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The infant seat is divided into multiple independently adjustable segments: upper body support portion, lower body support portion, and lateral containment supports. Each segment can be adjusted separately to achieve optimal positioning, allowing the seat to adapt to different infant positions and needs without requiring complex overall restructuring.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The seat incorporates dynamic adjustment capabilities through pivot connections and adjustment assemblies that enable the seat portions and restraints to change angles and positions. This allows the seat to transition between different configurations (upright, reclined, flat) to accommodate infant comfort needs while maintaining structural integrity.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If infant seats are adjusted manually by propping pillows or supports, then no complex adjustment mechanisms are needed, but the adjustment process disturbs the infant and is imprecise

Engineering Contradiction:

Improveease of angle adjustmentVSAvoidprecision of positioning

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent replaces the manual pillow-propping method with integrated mechanical adjustment assemblies that include pivot connections, locking mechanisms, and angle-indicating features. These mechanisms provide precise, controlled adjustment of seat portions without requiring external supports, ensuring accurate positioning while maintaining ease of operation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If infant seats have fixed side restraints, then the restraint system is simple and reliable, but the restraints cannot be adjusted to match changing infant positions and sizes

Engineering Contradiction:

Improveadjustability of lateral containment supportsVSAvoidcomplexity of restraint adjustment system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The lateral containment supports are designed with multi-functionality, serving both as safety restraints and as adjustable positioning elements. The same structural components provide both containment and angle adjustment capabilities, reducing the need for separate adjustment mechanisms and minimizing overall system complexity while maximizing adaptability.

Inventive Principle:

Principle #6Universality (Multi-functionality)
