Foam Panel Toy System With Segmented Edge Joints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foam panel systems with dovetail ends are not effective in maintaining orthogonal joints, allowing panels to easily separate when pulled horizontally, and limiting children's ability to create structures with desired configurations.
Innovation Solution
The foam panel system features edges with alternating hemispherical projections and recesses, allowing panels to lockably engage at any angle, enabling secure orthogonal joints and facilitating the creation of structures with varied configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If dovetail ends are used for interlockingly joining foam panels, then panels can be joined together, but the panels easily separate when pulled horizontally and do not maintain orthogonal joints
Solution Approach 1:
The edge of each foam panel is segmented into alternating protrusions and recesses rather than a continuous dovetail shape. This segmentation allows the protrusions to engage with recesses in multiple orientations (planar and orthogonal), providing reliable joint stability in both horizontal and vertical directions simultaneously
Solution Approach 2:
The protrusions and recesses are designed with asymmetric geometries that complement each other. The protrusions on one panel fit into corresponding recesses on adjacent panels, creating an asymmetric interlocking mechanism that prevents separation in multiple directions while maintaining ease of assembly
2Adaptability or versatility
If traditional orthogonal joint configurations are used, then panels can be joined at 90 degrees, but the joints do not stay together making structure construction difficult
Solution Approach 1:
The alternating protrusion-recess edge configuration serves multiple functions: it enables panels to join together in planar arrangements, orthogonal arrangements, and intermediate angles. This universal connection mechanism allows a single panel design to support multiple joint configurations, giving children versatility in structure creation while ensuring reliability in each configuration
3Ease of manufacture
If foam panels are designed for specific three-dimensional objects with tailored connection means, then the panels can form the specific object, but the panels do not facilitate children to create structures of their own configuration
Solution Approach 1:
The standardized alternating protrusion-recess edge design provides a universal connection language that works for any panel configuration. Children can assemble panels into various two-dimensional and three-dimensional structures without needing different connection mechanisms for different shapes, making both assembly easy and creative expression possible
