Solution Overview

Problem

Existing sliding puzzles, such as paper card and plastic types, lack stereo perception and funniness, and have components that are easily lost during assembly, leading to high production costs and low convenience of use.

Innovation Solution

A sliding puzzle with a cylindrical support featuring a guide rail structure and blocks that slide along it, connected through chutes and curved plates, allowing for easy assembly and reducing the risk of component loss, while maintaining structural stability and enabling smooth movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If blocks are fixed to the main body seat through buckles or magnetic suction, then the blocks are securely attached, but the components are easy to lose during assembly and the assembly process is complex

Engineering Contradiction:
Improveblock attachment securityVSAvoidassembly process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the complex fastening mechanisms (buckles, magnetic suction) and replaces them with a simple guide rail structure. The blocks are equipped with guide rails that slide into corresponding slots on the support, eliminating the need for separate fastening components and significantly simplifying the assembly process while maintaining secure attachment.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent segments the block structure into distinct components: a block body and an integrated guide rail. This segmentation allows the guide rail to be a separate, easily attachable component that simplifies assembly while ensuring reliable connection through the sliding mechanism.

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If multiple blocks are assembled one by one through fastening, then the structure is stable, but the assembly time is long and production efficiency is low

Engineering Contradiction:
Improvestructural stabilityVSAvoidassembly efficiency
Core Design Contradiction:
Stability of the object's compositionVSProductivity

Solution Approach 1:

The patent removes the time-consuming fastening steps by extracting the core function of attachment and implementing it through a simple slide-in guide rail mechanism. This allows blocks to be quickly assembled without repeated fastening operations, significantly improving production efficiency while maintaining structural stability.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of operation

If traditional sliding puzzle structures are used, then the assembly is simple, but the stereo perception is poor and the toy is less engaging

Engineering Contradiction:
Improveassembly simplicityVSAvoidstereo perception and engagement
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent transitions from traditional 2D paper card or flat plastic sliding puzzles to a 3D cylindrical structure. The blocks are arranged on a cylindrical support with guide rails that extend in multiple directions, providing true stereo perception and enhanced engagement while maintaining assembly simplicity through the standardized guide rail interface.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Reliability

If the entire sliding puzzle is replaced due to local damage, then the functionality is restored, but the production cost increases

Engineering Contradiction:
Improvefunctional reliabilityVSAvoidproduction cost
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The patent segments the sliding puzzle into independently replaceable components: the cylindrical support and individual blocks with integrated guide rails. This allows damaged blocks to be replaced individually rather than replacing the entire puzzle, significantly reducing production costs while maintaining functional reliability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent enables selective replacement of damaged blocks while retaining undamaged components. The standardized guide rail interface ensures that replaced blocks can be easily recovered and reused in future replacements, reducing overall material consumption and production costs.

Inventive Principle:
Principle #34Discarding and recovering
