Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing craft construction kits using spherical beads are difficult to use due to limited contact areas, small size making them hard to handle, and instability when trying to stack them vertically, leading to time-consuming construction processes and potential adhesion issues with the tray.
Innovation Solution
A kit comprising blocks with a main body made from a water-activated adherent material, featuring a top block projection and a bottom aperture with specific shape regions for interlocking and tray projection compatibility, allowing for stable vertical stacking and preventing adhesion to the tray.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If spherical beads are used, then the kit can be simple in design, but the contact area between beads is limited and they are difficult to handle
Solution Approach 1:
The patent transitions from spherical beads to blocks with curved surfaces. The blocks feature rounded corners and smooth curved surfaces that maintain aesthetic appeal while providing larger flat contact areas for stable stacking and easier handling, resolving the contradiction between simple design and ease of operation.
2Device complexity
If spherical beads are used, then the kit design is simple, but vertical stacking is unstable
Solution Approach 1:
The blocks incorporate curved surfaces with specific radius of curvature that enable stable vertical stacking. The rounded corners and smooth transitions provide stable contact points, allowing blocks to be stacked directly one on top of another without requiring individual layer construction, thus improving stacking stability while maintaining design simplicity.
3Strength
If water-activated adherent material is used, then blocks can adhere to each other, but blocks may adhere to the tray
Solution Approach 1:
The patent applies different surface properties to different parts of the block. The exterior surfaces are made from water-activated adherent material to enable block-to-block adhesion, while the bottom surfaces have modified properties (different material composition or surface treatment) that prevent adhesion to the tray, allowing selective adhesion behavior in different locations.
Solution Approach 2:
The patent introduces an intermediary layer or coating on the bottom surfaces of blocks that acts as a barrier between the water-activated adherent material and the tray. This intermediary prevents unwanted adhesion to the tray while preserving the adhesion capability between blocks.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The kit enables efficient and stable construction of crafts with vertical walls by allowing blocks to adhere securely when wet, while preventing unwanted adhesion to the tray, thus simplifying the construction process and enhancing user experience.
Implementation Method 1
Each block has a main body having an exterior surface that is made from a material that is adherent when exposed to water so as to permit a first block from the plurality of blocks to be adherable to a second block of the plurality of blocks by applying water to at least one of the first and second blocks

AI summary
In an aspect, a kit is provided for constructing a craft, and includes a plurality of blocks. Each block has a main body having an exterior surface that is made from a material that is adherent when exposed to water so as to permit the blocks to adhere to one another. Each block further includes a top surface and a block projection extending from the top surface. Each block further includes a bottom aperture extending into the main body towards the top surface, and defining a longitudinal axis. The bottom aperture includes a first aperture region that is shaped to receive the block projection of the second block of the plurality of blocks. The bottom aperture includes a second aperture region that is shaped to receive a distal portion of a block tray projection on a block tray.
