Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rocking solutions are limited in their portability, versatility, and flexibility, requiring large spaces, being expensive, and not easily adaptable for use with existing furniture, making them unsuitable for continuous rocking motions, especially for individuals with mobility issues or caregivers needing to rock infants while performing other tasks.
Innovation Solution
A portable rebounding device with a spring mechanism between a front and rear member, allowing users to position it against a stationary surface, providing a gentle rocking motion with reduced strain, and designed for comfort and ease of use with various supporting surfaces, including furniture, without the need for extensive space or additional equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional rocking furniture is used, then rocking function is provided, but portability and adaptability are poor
Solution Approach 1:
The rocking device is divided into separate components: a rebounding element (spring or elastic material), a positioning element, and a housing. This segmentation allows the device to be portable and adaptable to different surfaces while maintaining functionality. The rebounding element can be independently positioned against various stationary surfaces (walls, furniture, floors) without requiring a complex integrated structure.
Solution Approach 2:
The device is designed to work with multiple types of stationary surfaces including walls, furniture, and floors. The rebounding element can be positioned at different orientations and locations, allowing the same device to provide rocking functionality in various settings and configurations, making it universally applicable across different environments.
2Ease of operation
If conventional rocking solutions are used, then rocking motion is provided, but space requirements are large
Solution Approach 1:
Instead of requiring horizontal floor space, the device utilizes vertical space by positioning the rebounding element against a stationary surface. The rocking motion is generated through compression and rebound in the vertical or depth dimension rather than requiring lateral movement, thereby eliminating the need for large floor space while maintaining ease of operation.
3Reliability
If conventional rocking furniture is used, then rocking function is provided, but cost is high
Solution Approach 1:
The device uses simple, inexpensive components such as springs, elastic materials, or foam that can be manufactured at low cost. Rather than using expensive traditional rocking furniture materials and complex craftsmanship, the invention employs readily available, easily manufactured elements that provide reliable rocking functionality at a fraction of the cost.
Solution Approach 2:
The rebounding element (spring or elastic material) provides the rocking motion automatically through its own elastic properties when compressed by the user's weight or movement. This self-service mechanism eliminates the need for complex mechanical linkages, motors, or additional energy sources, reducing manufacturing complexity and cost while maintaining reliable operation.
4Duration of action of moving object
If prolonged rocking in seated position is performed, then rocking benefits are achieved, but muscle and joint strain increases
Solution Approach 1:
The rebounding element acts as a counterweight system that supports the user's weight and provides upward reactive force during rocking. When the user compresses the spring or elastic material, it stores energy and then rebounds, providing a cushioning effect that reduces the impact on muscles and joints. This allows prolonged rocking with significantly reduced physical strain compared to active rocking without support.

Function Achieved in This Case
The device offers a convenient, cost-effective, and comfortable rocking motion that can be used in various settings, reducing physical effort and strain, allowing continuous rocking while accommodating users' needs for mobility and simultaneous tasks like nursing or relaxation.
Implementation Method 1
a spring mechanism positioned between the front and rear members
Implementation Method 2
The rebounding device exerts a biasing force when compressed that gently propels the user's upper body forward
