Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional toy construction assemblies are difficult to assemble and prone to falling apart when handled roughly, resulting in unstable structures.
Innovation Solution
A toy connection system comprising wall panels with connecting edges and slots, and clips with receiving channels and tabs that securely engage these slots to form stable connections using clips such as corner, flex, and hinge clips.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional toy construction pieces are used, then the assembly process is simple, but the resulting structures are unstable and fall apart easily
Solution Approach 1:
The connection system is segmented into distinct components: wall panels with slots, clips with receiving channels, and tabs. This segmentation allows each component to be optimized independently for both ease of assembly and structural stability, resolving the contradiction between simple assembly and stable construction.
Solution Approach 2:
The tab is nested within the slot of the wall panel, while the receiving channel nests the connecting edge. This nested configuration creates interlocking joints that are both easy to assemble (simple insertion) and structurally stable (interlocked geometry prevents disassembly under normal play forces).
2Reliability
If conventional toy construction pieces are used, then the design is simple, but the pieces are difficult to assemble and fall apart easily
Solution Approach 1:
The connection system is designed to be self-aligning and self-securing. The tab automatically aligns with the slot during assembly, and the interlocking geometry self-secures the connection without requiring additional fastening steps. This achieves high connection reliability without proportionally increasing device complexity.
Solution Approach 2:
The slots and receiving channels are designed with specific geometric parameters (width, length, orientation) that optimize both assembly ease and connection reliability. By carefully controlling these dimensional parameters, the system achieves reliable connections while maintaining relatively simple component designs.
3Strength
If conventional toy construction pieces are used, then the materials are simple, but the structures are not durable when handled roughly
Solution Approach 1:
The connection system utilizes composite construction where plastic wall panels are combined with metal or rigid plastic clips. This composite approach enhances connection strength and durability against rough handling while maintaining ease of manufacture through standard molding and stamping processes for each material type.
Solution Approach 2:
The connection strength is enhanced by adding dimensional complexity to the joint geometry. The three-dimensional interlocking shape of tabs, slots, and receiving channels provides mechanical strength in multiple directions, improving durability without requiring additional materials or complex manufacturing processes.

AI summary
Toy connection systems comprise a plurality of planar wall panels and a plurality of clips each configured to connect one or more of the planar wall panels to each other. Each wall panel comprises at least one connecting edge and at least one slot. Each clip comprises at least one receiving channel configured to releasably receive the connecting edge of a respective one of the wall panels and a tab that is configured to be received within the slot of the wall panel to secure the wall panel to the clip. In some examples, the clips are configured to be biased against the wall panels that are connected using the clip, such that the tab of the clip is configured to be snapped into the slot of the wall panel that is received within the receiving channel of the clip.
