Solution Overview

Problem

Existing jigsaw puzzle tables have fixed heights that do not accommodate users of varying heights, requiring them to physically move around to access different areas of the puzzle, and lack a mechanism to retain unfinished pieces conveniently.

Innovation Solution

A movable puzzle platform with a rotating assembly that allows the puzzle board to be rotated and adjusted in height, featuring a first and second moving member with rolling portions and rotors, and a supporting assembly for convenient puzzle piece assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the jigsaw puzzle table has a fixed height, then the structure is simple and stable, but it cannot accommodate users of varying heights and reduces comfort

Engineering Contradiction:
Improveheight adaptabilityVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by transforming the fixed-height table into an adjustable-height table. The table leg includes a telescopic structure with multiple segments that can extend and retract, allowing the table height to be dynamically adjusted to suit different user heights and playing scenarios, thereby resolving the contradiction between height adaptability and structural complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent applies the nesting principle in the telescopic leg structure where one leg segment is inserted within another. The first leg segment contains the second leg segment, which in turn contains the third leg segment, creating a nested configuration that enables height adjustment while maintaining a compact form when retracted.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Area of stationary object

If the puzzle board is large to accommodate more pieces, then the game area is sufficient, but the user cannot reach all areas and must physically move around

Engineering Contradiction:
Improvegame areaVSAvoidaccessibility
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The patent applies the dynamics principle by introducing a rotating assembly that allows the puzzle board to rotate relative to the user. The rotating mechanism enables the user to access different areas of the large puzzle board by rotating it into position, eliminating the need for the user to physically move around and maintaining ease of operation despite the enlarged game area.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The rotating assembly is segmented into multiple components including a first rotating member, a second rotating member, and a connecting structure. This segmentation allows the rotation function to be integrated into the table structure without significantly increasing overall complexity, while providing the capability to access all areas of the large puzzle board.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If the puzzle board rotates freely, then accessibility to all areas is improved, but the position becomes unstable

Engineering Contradiction:
ImproveaccessibilityVSAvoidposition stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent applies the preliminary anti-action principle by incorporating a locking mechanism that prevents unintended rotation of the puzzle board. The locking structure engages with the rotating assembly to secure the puzzle board at desired positions, counteracting the potential instability caused by free rotation and ensuring position stability during puzzle assembly.

Inventive Principle:
Principle #9Preliminary anti-action

4Adaptability or versatility

If the table leg is telescopic for height adjustment, then height adaptability is improved, but the structure becomes more complex

Engineering Contradiction:
Improveheight adjustabilityVSAvoidleg structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the nesting principle in the telescopic leg structure where one leg segment is inserted within another. The first leg segment contains the second leg segment, which in turn contains the third leg segment, creating a nested configuration that enables height adjustment while maintaining a compact form when retracted.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent applies the dynamics principle by transforming the fixed-height table into an adjustable-height table. The table leg includes a telescopic structure with multiple segments that can extend and retract, allowing the table height to be dynamically adjusted to suit different user heights and playing scenarios, thereby resolving the contradiction between height adaptability and structural complexity.

Inventive Principle:

AI summary

A rotating assembly and a jigsaw puzzle table using the rotating assembly are disclosed in present disclosure. The jigsaw puzzle table includes a board portion comprising a bottom surface, at least two puzzle drawers, a reinforcing arm connected to the bottom surface of the board portion, a first pivoting arm connected to the bottom surface of the board portion, a supporting shaft located below the board portion and spaced apart from the first pivoting arm; and at least one rotating connection component connecting the first pivoting arm and the supporting shaft. The rotating connection component is configured to enable the board portion to switch between a flat position and a tilted position. The board portion is capable of being rotated through a rotational movement of the rotating assembly.
