Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the jigsaw puzzle table is made fixed and non-adjustable, then the structure is simple and stable, but the adaptability and ease of operation deteriorate

Engineering Contradiction:

ImproveadaptabilityVSAvoidstructure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by transforming the fixed puzzle table into an adjustable one. The table top can be rotated around a vertical axis through a rotatable support column, and the height can be adjusted via a telescopic support column with locking mechanisms. This allows the table to adapt to different user needs and positions while maintaining structural stability through proper mechanical design.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent segments the support column into multiple functional components: a rotatable support column for angle adjustment, a telescopic support column for height adjustment, and locking mechanisms for position fixation. This segmentation allows each component to perform its specific function independently, achieving both adaptability and structural clarity.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If the jigsaw puzzle table height is fixed, then the manufacturing is simple, but the ease of operation and comfort for different users deteriorate

Engineering Contradiction:

Improveease of operationVSAvoidease of manufacture

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

The height adjustment mechanism transforms the static table into a dynamic one that can adapt to different user heights. The telescopic support column with interlocking segments and locking pins allows smooth height adjustment while maintaining manufacturing simplicity through standardized mechanical components.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The locking mechanism acts as an intermediary between the telescopic support column segments, enabling easy height adjustment while maintaining structural integrity. This intermediary component simplifies the user interaction (pulling the locking pin) while ensuring the manufactured parts remain relatively simple and standardized.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If the jigsaw puzzle table cannot be rotated, then the structure is stable and simple, but the adaptability and user comfort deteriorate

Engineering Contradiction:

ImproveadaptabilityVSAvoidease of operation

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The rotatable support column introduces rotational freedom to the previously static table structure. The column can rotate 360 degrees around the vertical axis, allowing users to position the table at any angle relative to chairs or other users, significantly improving adaptability and ease of operation in social settings.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The rotatable mechanism provides multi-functionality by allowing the same table structure to serve multiple users from different positions and angles. This universal design enables the table to adapt to various seating arrangements and user configurations without requiring multiple separate tables.

Inventive Principle:

Principle #6Universality (Multi-functionality)
