Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a motorized adjustable wrench is used, then productivity and ease of operation are improved, but device complexity increases

Engineering Contradiction:

Improvefastening and removal speedVSAvoidmechanical communication system

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent replaces the manual mechanical operation with an automated motorized system. The motorized adjustable wrench uses an electric motor to drive the wrench head through a gear mechanism, substituting human manual effort with automated mechanical power. This resolves the contradiction by significantly improving productivity while the complexity is managed through standardized mechanical components.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The wrench head is designed with adjustable settings to accommodate different nut sizes and types. The universal design allows a single device to perform multiple fastening and removal tasks across various applications, improving productivity without requiring multiple specialized tools, thus justifying the increased device complexity through enhanced versatility.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If a motorized adjustable wrench is used, then ease of operation is improved, but device complexity increases

Engineering Contradiction:

Improvemanual labor reductionVSAvoidmechanical communication system

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The motorized adjustable wrench is designed to perform the fastening and removal operations autonomously once activated. The motor automatically drives the wrench head to engage and rotate nuts, eliminating the need for continuous manual manipulation. This self-service capability significantly improves ease of operation while the complexity is contained within the automated drive mechanism.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical operation with automated motorized operation. The electric motor drives the wrench head through a gear mechanism, substituting human manual effort with automated mechanical power. This resolves the contradiction by significantly improving productivity while the complexity is managed through standardized mechanical components.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Device complexity

If traditional manual wrenches are used, then device complexity is reduced, but productivity and ease of operation worsen

Engineering Contradiction:

Improvemechanical structureVSAvoidfastening and removal efficiency

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The invention changes the operational parameters from manual control to motorized control with adjustable speed and torque settings. The motorized system allows for variable operational parameters that can be optimized for different nut sizes and applications, improving productivity while the complexity is managed through electronic control systems.
