Solution Overview

Problem

Conventional infant safety seats cannot simultaneously shift and rotate the seat body relative to the seat base, leading to complex and time-consuming operations.

Innovation Solution

A rotatable safety seat design featuring a seat body and seat base with a sliding rotation component that allows the seat body to be both shifted and rotated via a sliding movement, utilizing a slidable connection between the seat body and seat base, enabling simultaneous shifting and rotation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the seat body is rotated on its own axle above the seat base, then the seat body can be adjusted to different angles, but the seat body cannot be linearly shifted relative to the seat base during rotation

Engineering Contradiction:

Improveseat body adjustment capabilityVSAvoidoperation complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The rotation component is divided into multiple segments including a first curved slot, second curved slot, first pin, and second pin. Each segment performs a specific function in the simultaneous shifting and rotation mechanism, allowing the seat body to achieve both linear displacement and angular adjustment through coordinated movement of these segmented components

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The rotation component acts as an intermediary mechanism between the seat body and seat base. It includes a first curved slot and second curved slot that guide the movement, with pins serving as intermediaries to translate the sliding motion into simultaneous shifting and rotation of the seat body relative to the seat base

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the seat body is shifted to a different position before rotation, then the seat body can reach the desired position, but the operation time is elongated

Engineering Contradiction:

Improveseat body positioning capabilityVSAvoidadjustment execution time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The invention merges the shifting and rotation operations into a single integrated action. The rotation component with its curved slots and pins enables the seat body to be simultaneously shifted linearly and rotated angularly through one sliding movement, combining what were previously two separate operations into one unified motion sequence

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The curved slots in the rotation component are pre-designed with specific geometries that guide the pins through predetermined paths. This preliminary design of the slot shapes ensures that as the pin slides along the curved path, the seat body automatically performs the correct sequence of shifting and rotation without requiring separate adjustment steps

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If the seat body is shifted and rotated separately, then the seat body can reach the desired position, but the operation becomes complicated

Engineering Contradiction:

Improveseat body movement capabilityVSAvoidmechanism complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The rotation component serves multiple functions simultaneously: it guides the linear shifting of the seat body, enables angular rotation, and provides the mechanical linkage between these movements. The curved slots and pins work together as a universal mechanism that performs both translation and rotation functions within a single integrated structure

Inventive Principle:

Principle #6Universality (Multi-functionality)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This design simplifies the operation by allowing the seat body to be easily moved closer to or away from a caretaker, improving convenience and reducing the time required for adjustments, while maintaining a stable and smooth sliding and rotating mechanism.

Implementation Method 1

The rotation component is engaged with the seat body and slidably connected on the seat base. The seat body is shifting and rotating on the seat base via a sliding movement of the rotation component.

Methodology Applied

Scientific EffectSliding movement: Friction

AI summary

The present invention provides a rotatable safety seat (100) includes a seat body (1), a seat base (2) and a rotation component (3). The rotation component (3) is slidably connected between the seat body (1) and the seat base (2). The seat body (1) is slid relative to the seat base (2) via simultaneous shifting and rotation. The rotation component (3) is slidably connected between the seat body (1) and the seat base (2). During slid of the seat body (1), the seat body (1) is shifted due to the slide, the seat body (1) is shifted because of the slide; the seat body (1) is rotated when being shifted, so that the infant or the child on the seat body (1) is moved close to or away from the caretaker according to the actual demand. The present invention further provides a carrier with the rotatable safety seat (100).
