Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional baby walkers made of rigid materials pose a risk of injury due to rapid wheel movement and inertia impact, lacking control and safety for toddlers.
Innovation Solution
A multifunctional baby walker with a body made of polyurethane high-density foaming material and slidable legs, providing a soft texture and stable support, replacing wheels to prevent inertia impact and allowing for independent walking, while also serving as water recreation articles and building block toys with cartoon designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If conventional baby walkers use rigid materials and wheels, then mobility is improved, but safety deteriorates due to rapid rolling and large inertia impact
Solution Approach 1:
The patent changes the material parameter from rigid materials to soft sponge material, and changes the movement mechanism from wheels to slidable legs. This transforms the movement from rapid rolling to controlled sliding, reducing inertia impact while maintaining mobility. The soft material absorbs impact forces, eliminating the harmful effects of rapid rolling.
Solution Approach 2:
The patent converts the potential harm of rapid movement into benefit by using soft sponge material that absorbs impact energy. The slidable legs convert the harmful inertial forces into controlled, gradual movement. The soft material's deformation during movement absorbs energy that would otherwise cause injury, turning a harmful physical phenomenon into a protective mechanism.
2Strength
If conventional baby walkers use rigid materials, then structural strength is improved, but safety deteriorates due to lack of cushioning
Solution Approach 1:
The patent changes the material parameter from rigid to soft sponge material. This fundamental parameter change provides both structural integrity and cushioning properties. The sponge material maintains sufficient strength to support the baby's weight while simultaneously providing shock absorption and cushioning to prevent bruising and injury.
Solution Approach 2:
The patent uses sponge material as a composite solution that combines structural support function with shock absorption function. The sponge material's cellular structure provides both mechanical strength and energy absorption capabilities, eliminating the need for separate rigid and cushioning components.
3Object-affected harmful factors
If the baby walker uses a soft sponge body, then safety is improved by reducing inertia impact, but manufacturing complexity increases
Solution Approach 1:
The patent merges the body structure and the cushioning function into a single integrated sponge body. The slidable legs are integrated directly with the sponge body, eliminating the need for separate rigid frames and cushioning layers. This merging simplifies manufacturing by reducing the number of components and assembly steps, despite using soft sponge material.
Solution Approach 2:
The sponge body serves multiple functions simultaneously: it provides structural support, shock absorption, cushioning, and a comfortable surface for the baby. The slidable legs provide both movement capability and impact reduction. This multi-functionality reduces the overall system complexity and manufacturing requirements.
