Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the workbench is made detachable and combinable to accommodate different working environments, then the adaptability and ease of movement are improved, but the mechanical strength and stability deteriorate

Engineering Contradiction:

ImproveadaptabilityVSAvoidmechanical strength

Core Design Contradiction:

Adaptability or versatilityVSStrength

Solution Approach 1:

The workbench is divided into multiple detachable modules (primary workbench and secondary workbench) that can be independently assembled or separated. Each module maintains structural integrity through internal reinforcement, while the connection between modules uses specialized locking mechanisms to ensure stability during operation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The workbench transitions from a static fixed structure to a dynamic reconfigurable system. The quick locking mechanism enables rapid transformation between locked (stable) and unlocked (mobile) states, allowing the workbench to adapt its configuration based on operational requirements while maintaining stability when assembled.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If the workbench is made detachable and combinable to accommodate different working environments, then the ease of operation and labor saving are improved, but the stability deteriorates

Engineering Contradiction:

Improveease of movementVSAvoidstability

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The connection system uses simple, robust locking components designed for rapid engagement and disengagement. The locking sockets and plates are engineered for durability with sufficient service life for repeated assembly cycles, prioritizing ease of operation while maintaining adequate stability during use.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Ease of operation

If a quick locking mechanism is used to enable easy locking and separation, then the ease of operation is improved, but the device complexity increases

Engineering Contradiction:

Improveease of lockingVSAvoidstructure complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

Multiple locking functions are integrated into a unified quick locking mechanism. The locking socket and rotating plate work together as a single operational unit, where one rotational motion simultaneously engages or disengages the locking connection, simplifying the user interaction despite the mechanical complexity of the underlying structure.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The quick locking mechanism is designed to be self-actuating through the rotational motion of the locking plate. The inclined planes and stop tabs automatically guide the locking engagement without requiring additional actuators or complex control systems, reducing operational complexity while maintaining ease of use.

Inventive Principle:

Principle #25Self-service

4Reliability

If the locking portions are rotated to overlap with stop tabs to implement locking, then the reliability is improved, but the ease of operation deteriorates

Engineering Contradiction:

Improvelocking reliabilityVSAvoidoperation complexity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The locking plate's fan-shaped geometry and the inclined planes on the stop tabs are pre-configured to guide the locking engagement. As the locking plate rotates, the inclined surfaces automatically align and guide the locking portions onto the stop tabs, ensuring reliable engagement without requiring precise manual positioning by the operator.

AI summary

The present utility model relates to an interlockable workbench, including a primary workbench (1) and a secondary workbench (2) between which a quick locking mechanism (3, 4) is disposed. Because a quick locking mechanism (3, 4) is disposed between the primary workbench (1) and the secondary workbench (2), the workbench can be freely locked and separated according to an actual requirement.
