Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a gear worm and gear wheel mechanism is used to rotate the arm member, then the phase of signals can be changed, but significant power loss occurs due to friction

Engineering Contradiction:

Improvephase changing capabilityVSAvoidpower loss

Core Design Contradiction:

Ease of operationVSLoss of energy

Solution Approach 1:

The patent extracts and eliminates the gear worm and gear wheel mechanism from the phase shifter design. Instead of using this mechanical transmission system, the invention directly connects the rotation member to the arm member through a guide member, removing the source of friction-induced power loss while preserving the phase changing capability.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The guide member serves as an intermediary element that directly transmits rotational motion from the rotation member to the arm member. This eliminates the need for gear transmission and reduces power loss by providing a direct mechanical coupling path without intermediate frictional interfaces.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Power

If a gear worm and gear wheel mechanism is used, then rotary power can be transmitted to the arm member, but the efficiency of power delivery is reduced

Engineering Contradiction:

Improverotary power transmissionVSAvoidpower delivery efficiency

Core Design Contradiction:

PowerVSProductivity

Solution Approach 1:

The patent removes the gear transmission system that caused power delivery inefficiency. By eliminating the gear worm and gear wheel, the invention achieves direct power transmission from the rotation member to the arm member through the guide member, significantly improving power delivery efficiency.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The direct connection through the guide member ensures continuous and uninterrupted power transmission from the rotation member to the arm member. This eliminates the intermittent and loss-prone gear meshing action, maintaining continuous useful mechanical action throughout the power transmission path.

Inventive Principle:

Principle #20Continuity of useful action
