Recessed Peg Puzzle Base with Shielded Cutouts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional puzzles with outward-sticking pegs pose a safety risk to children, as they can cause accidental injury, and are not suitable for young children who may not be able to intellectually use them effectively.
Innovation Solution
A safe puzzle design featuring deep cutouts within a base block that shields pegs inside, allowing them to be either at the same height or below the surface, providing a gap for hand manipulation and reducing the risk of injury, while incorporating various shapes and learning mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pegs stick outward from the puzzle surface to enable child interaction, then ease of operation is improved, but safety is worsened due to risk of tripping and falling
Solution Approach 1:
The pegs are nested inside deep cutouts within the base block, with only a portion visible above the surface. This nesting approach allows the pegs to remain accessible for child interaction while being partially concealed to eliminate tripping hazards, directly resolving the contradiction between ease of operation and safety
Solution Approach 2:
The cutouts are designed with specific dimensions creating a gap between the pegs and cutout walls, providing localized hand manipulation space. This local quality modification enables safe interaction by ensuring sufficient clearance for small hands to grasp and manipulate blocks without risking injury from exposed pegs
2Object-affected harmful factors
If pegs are placed at or below the base block surface to eliminate safety hazards, then safety is improved, but ease of operation deteriorates due to reduced accessibility
Solution Approach 1:
The pegs are nested within deep cutouts but extend partially above the base block surface, creating an optimal balance. This partial exposure ensures safety by preventing tripping while maintaining ease of operation through accessible peg tops that children can easily interact with
Solution Approach 2:
The cutout design creates a specific gap distance between the pegs and cutout walls, providing localized hand manipulation space. This ensures that even though pegs are recessed, children's hands can easily access and manipulate the blocks, maintaining ease of operation while improving safety

AI summary
A safe puzzle is configured with deep cutouts inside a base block, and inside the cutouts are respective pegs that are shielded by the surrounding walls. The base block may have multiple cutouts and inside each one is a peg that serves as the puzzle for the child. The cutouts can have a square peg, triangular peg, circular peg, and ovular peg that extends in a vertical direction from a floor of each cutout. A gap between the peg and the cutout's walls surrounds the pegs so that the child and a parent have sufficient space for their hand to manipulate the blocks, such as place the blocks over the pegs and remove the blocks from the pegs. The pegs have a height that is equal to or below the base block's top surface to create a safer environment for toddlers when playing with the puzzle.
