Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If metal conductive members are used to connect the massage component and rod body, then electrical conduction is achieved, but the conductive members are exposed and prone to oxidation and rust, causing discomfort and psychological barriers

Engineering Contradiction:

Improveconductive connection reliabilityVSAvoidoxidation and rust of conductive members

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical electrical connection system (exposed metal conductive members) with a wireless induction power supply system. The transmitter module is embedded in the rod body and the receiver module is embedded in the massage component, eliminating the need for exposed conductive members while maintaining reliable electrical connection through electromagnetic induction.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces electromagnetic fields as an intermediary to transfer energy between the rod body and massage component. The transmitter module generates an electromagnetic field that induces current in the receiver module, serving as a non-contact intermediary that eliminates the need for direct metal-to-metal contact and prevents oxidation and rust issues.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If exposed conductive sheets are used for power transmission, then electrical connection is established, but current passing through exposed sheets brings discomfort and psychological barriers to consumers

Engineering Contradiction:

Improveease of assemblyVSAvoiddiscomfort and psychological barriers from exposed current

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical system of exposed conductive sheets with a wireless induction power supply system. Energy is transmitted through electromagnetic fields without physical contact, eliminating the discomfort and psychological barriers associated with exposed current while maintaining ease of operation through modular design.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent embeds the transmitter and receiver modules within the structures of the rod body and massage component respectively, using the housing materials as protective shells that enclose the electrical components. This prevents exposure of current-carrying elements while maintaining the flexibility and ease of assembly of the modular design.

Inventive Principle:

Principle #30Flexible shells and thin films

3Object-affected harmful factors

If wireless induction power supply is used to power the massage component, then safety and consumer acceptance are improved, but device complexity increases due to additional modules

Engineering Contradiction:

Improvesafety and consumer acceptanceVSAvoidcomplexity of wireless power supply modules

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent merges the wireless power supply functionality with the existing structural components of the massage device. The transmitter module is integrated into the rod body structure and the receiver module is integrated into the massage component structure, combining multiple functions into unified assemblies that reduce overall system complexity despite adding wireless power capability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The wireless induction power supply system serves multiple functions: it provides electrical power transmission, eliminates the need for exposed conductive members, and enhances safety and consumer acceptance. This multi-functionality justifies the added complexity by delivering multiple benefits simultaneously.

Inventive Principle:

Principle #6Universality (Multi-functionality)
