Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple tools are used for multi-axis orientation adjustment, then the orientation adjustment capability is improved, but the device complexity increases

Engineering Contradiction:

Improvemulti-axis orientation adjustment capabilityVSAvoidnumber of tools required

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple orientation adjustment functions into a single hoist tool by integrating a rotatable hoist frame with adjustable couplings. The hoist frame can rotate about a rolling axis while the couplings can be repositioned to define different rolling axes, eliminating the need for multiple separate tools and achieving multi-axis orientation adjustment capability in one integrated device.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The hoist tool is designed with universal adaptability to perform multiple orientation adjustment functions. The adjustable couplings allow the tool to define different rolling axes, and the rotatable hoist frame enables rotation about these axes, making the single tool capable of performing what previously required multiple specialized tools.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple tools are used for multi-axis orientation adjustment, then the orientation adjustment capability is improved, but the manufacturing cost increases

Engineering Contradiction:

Improvemulti-axis orientation adjustment capabilityVSAvoidtool manufacturing cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By merging multiple orientation adjustment functions into a single hoist tool with a rotatable frame and adjustable couplings, the patent reduces the total number of tools that need to be manufactured. This consolidation decreases manufacturing costs while maintaining full multi-axis orientation adjustment capability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The universal design of the hoist tool, with its adjustable couplings and rotatable frame, allows one tool to replace multiple specialized tools. This multi-functionality reduces the overall manufacturing investment required while providing comprehensive orientation adjustment capabilities.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If multiple tools are used for multi-axis orientation adjustment, then the orientation adjustment capability is improved, but the number of operation steps increases

Engineering Contradiction:

Improvemulti-axis orientation adjustment capabilityVSAvoidnumber of operation steps

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent merges multiple orientation adjustment operations into a single integrated tool that can perform rotations about different axes. The adjustable couplings allow operators to reconfigure the rolling axis without changing tools, and the rotatable hoist frame enables continuous rotation, reducing the number of discrete operation steps required.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The hoist tool incorporates dynamic elements including a rotatable hoist frame that can rotate about a rolling axis, and adjustable couplings that can be repositioned to change the rolling axis orientation. This dynamic capability allows the tool to adapt to different orientation adjustment needs without requiring multiple static tools or complex multi-step procedures.

AI summary

Disclosed herein is a hoist tool including a hoist frame and a base structure. The hoist frame includes a structural framework having a first end and a second end and at least one first rotation-enabling coupling at the second end of the structural framework. The base structure includes at least one second rotation-enabling coupling configured to engage with the at least one first rotation-enabling coupling of the hoist frame. The at least one second rotation-enabling coupling of the base structure defines a rolling axis. The hoist frame is selectively movable by the hoist to position the at least one first rotation-enabling coupling into engagement with the at least one second rotation-enabling coupling and when coupled and when the assembled structure is coupled to the hoist frame, the hoist frame is selectively rotatable about the rolling axis, relative to the base structure, to enable a rollover of the assembled structure.
