Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If hard-wired connections are used between rotating and non-rotating bodies, then reliable power and data transfer is achieved, but rotation is prevented

Engineering Contradiction:
Improvepower and data transfer reliabilityVSAvoidrotation capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent replaces mechanical hard-wired connections with wireless communication technology. The rotating body and non-rotating body communicate power and data wirelessly, eliminating the mechanical connection constraint that prevented rotation while maintaining reliable transfer. This substitution of mechanical system with electromagnetic field-based wireless system resolves the contradiction between rotation capability and connection reliability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If wireless transfer is used between rotating and non-rotating bodies, then rotation is enabled, but interference and signal integrity issues arise

Engineering Contradiction:
Improverotation capabilityVSAvoidinterference and signal degradation
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces wireless communication signals as an intermediary medium to transfer power and data between the rotating and non-rotating bodies. This intermediary wireless transmission method enables rotation while avoiding direct mechanical contact that would cause interference. The wireless signals act as a mediator that can penetrate through the rotational interface without being disrupted by mechanical friction or contact interference.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stability of the object's composition

If multiple support structures are used to prevent rotation, then stability is improved, but rotation capability is lost

Engineering Contradiction:
Improvesystem stabilityVSAvoidrotation capability
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent segments the support structure into multiple independent support elements (first support, second support, third support) that can be selectively engaged or disengaged. This segmentation allows the system to achieve stability when needed while maintaining the capability to rotate by selectively releasing the support segments. The divided support structure provides stability during operation but does not permanently constrain rotation.

Inventive Principle:
Principle #1Segmentation

AI summary

A support assembly for supporting a rotating body may include first and second supports defining first and second longitudinal support axes and configured to support the rotating body, such that the rotating body is rotatable relative to the first and second supports. A rotation axis about which the rotating body rotates may be transverse to the first and second longitudinal support axes. The support assembly may also include a spine coupled to the first and second supports. The support assembly may also include a motor associated with at least one of the first or second supports and configured to supply torque to rotate the rotating body. At least one of the spine, the first support, or the second support may define a recess configured to receive at least one of an electrical conductor or a data signals link associated with operation of the rotating body.
