Solution Overview

Problem

Existing children's jigsaw puzzles lack multifunctionality, leading to reduced entertainment value after completion, and require separate chalkboards that occupy space and are inconvenient to use, causing neck strain and difficulty in storage.

Innovation Solution

A multifunctional jigsaw puzzle board integrating a jigsaw puzzle area and a chalkboard area with a storage compartment, featuring a foldable support stand for ergonomic use and adjustable tilt, and a sliding storage box for organized storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a standalone chalkboard is used, then writing function is provided, but space occupation increases and device complexity increases

Engineering Contradiction:
Improvewriting functionVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the chalkboard writing function with the jigsaw puzzle board by integrating a chalkboard surface onto the rear side of the puzzle board body. This merging allows the single device to serve both puzzle assembly and writing/drawing purposes, eliminating the need for separate standalone chalkboards and reducing overall device complexity while maintaining versatility.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The jigsaw puzzle board is designed with multi-functionality by incorporating both puzzle pieces for assembly and a chalkboard surface for writing activities. This universal design enables the board to fulfill multiple functions (puzzle solving, writing, drawing) within a single device, addressing the adaptability requirement without proportionally increasing complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If children lean over to assemble puzzles for extended periods, then puzzle assembly is possible, but neck strain occurs

Engineering Contradiction:
Improvepuzzle assemblyVSAvoidneck strain
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a support stand with adjustable tilt angles that can be folded and extended. This dynamic support structure allows the puzzle board to be positioned at optimal viewing angles, reducing the need for children to lean over extended periods and thereby minimizing neck strain while maintaining ease of puzzle assembly.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The support stand provides dimensional adjustment by allowing the board to be tilted at different angles rather than remaining fixed in a horizontal position. This angular adjustment in the vertical dimension enables children to view the puzzle pieces at more comfortable heights and angles, reducing neck strain during extended assembly periods.

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

3Device complexity

If no dedicated storage compartments are provided, then device simplicity is maintained, but puzzle pieces and accessories are easy to lose and cleanup becomes inconvenient

Engineering Contradiction:
Improvedevice simplicityVSAvoidstorage and cleanup
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The patent incorporates a storage box with multiple compartments that nests within or attaches to the puzzle board structure. This nested storage solution provides dedicated compartments for organizing puzzle pieces, markers, and accessories, making it easier to keep items organized and simplified cleanup procedures, while adding minimal complexity to the overall device.

Inventive Principle:
Principle #7Nested doll (Nesting)

4Adaptability or versatility

If a multifunctional board is created, then entertainment value and utility are increased, but device complexity increases

Engineering Contradiction:
Improveentertainment valueVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges the jigsaw puzzle function and chalkboard writing function into a single integrated board structure. By combining these two distinct entertainment functions in one device, the patent increases overall entertainment value and utility while managing device complexity through functional integration rather than separate components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The board is designed as a universal toy that can serve multiple purposes: puzzle assembly for cognitive development and writing/drawing for creative expression. This multi-functionality approach maximizes entertainment value and practical utility, allowing children to engage with the board in diverse ways while maintaining a relatively simple unified structure.

Inventive Principle:
Principle #6Universality (Multi-functionality)
