Solution Overview

Problem

Conventional rocking solutions are limited in their versatility, flexibility, and portability, requiring significant space and being expensive, and cannot be easily integrated with existing furniture or used during travel, posing challenges for individuals needing rocking assistance for prolonged periods.

Innovation Solution

A portable rebounding device with a spring mechanism between a front and rear member, allowing users to generate a gentle rocking motion against a stationary surface, reducing strain and requiring minimal effort, and being adaptable to various environments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional rocking furniture is used, then rocking function is provided, but portability and flexibility are reduced

Engineering Contradiction:

Improveportability and flexibilityVSAvoidfurniture structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The rocking device is divided into separate components: a rebounding member with spring mechanism that can be detached from the support surface. This segmentation allows the rocking function to be portable while the support structure remains stationary, resolving the contradiction between portability and structural complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The rebounding member can be used with multiple different support surfaces (chairs, beds, sofas, walls) without modification. This universal application allows one device to provide rocking functionality across various furniture types, improving adaptability without requiring complex multi-functional furniture designs.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If conventional rocking solutions are deployed in multiple locations, then rocking assistance is available, but cost increases

Engineering Contradiction:

Improveavailability across locationsVSAvoidnumber of devices required

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

By separating the active rebounding mechanism from the support surface, the system allows one rebounding member to be moved and reused across multiple locations. Instead of deploying identical complete rocking chairs in every room, a single rebounding member can serve multiple support surfaces throughout the facility, reducing the total number of devices needed.

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If conventional rocking furniture is used, then rocking function is provided, but space requirements increase

Engineering Contradiction:

Improvespace efficiencyVSAvoidfloor space

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The separation of the rebounding member from the support surface allows the rocking function to be implemented on existing furniture without requiring dedicated rocking chair space. The compact rebounding member requires minimal additional space compared to full-sized rocking furniture, improving space efficiency in small rooms.

Inventive Principle:

Principle #1Segmentation

4Adaptability or versatility

If conventional rocking furniture is used, then rocking function is provided, but integration with existing furniture is limited

Engineering Contradiction:

Improveintegration capabilityVSAvoidmodification requirements

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The rebounding member is designed to work with various support surfaces including chairs, beds, sofas, and walls without requiring modifications to the existing furniture. This universal compatibility enables easy integration with existing furniture pieces while maintaining simplicity and avoiding complex modification requirements.

Inventive Principle:

Principle #6Universality (Multi-functionality)
