Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If hard-wired electrical cables are used to connect remote dispensing apparatus to the main purification unit, then reliable electrical communication is achieved, but the system becomes cumbersome and noisy, and placement flexibility is limited

Engineering Contradiction:

Improveelectrical communication reliabilityVSAvoidplacement flexibility

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical electrical cable connection system with a wireless electromagnetic communication system. The remote dispensing apparatus communicates with the main purification unit via wireless signals, eliminating the need for physical electrical cables while maintaining reliable communication and control functionality.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces wireless transceivers as intermediary devices that enable communication between the remote dispensing apparatus and the main purification unit without direct electrical contact. These transceivers act as mediators that transfer control signals and data through electromagnetic waves instead of physical conductors.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple remote dispensing apparatus are connected to a single main purification unit, then dispensing versatility is improved, but extensive cabling infrastructure is required

Engineering Contradiction:

Improvedispensing versatilityVSAvoidcabling infrastructure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent replaces the extensive electrical cabling infrastructure with wireless communication technology. Multiple remote dispensing apparatus can communicate with the main purification unit simultaneously through wireless signals, eliminating the need for separate electrical cables for each device and reducing overall system complexity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The wireless communication system provides a universal interface that can support multiple remote dispensing apparatus without requiring separate cabling infrastructure. The main purification unit can communicate with any number of remote devices through the wireless medium, making the system highly versatile and easily expandable.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If the remote dispensing apparatus is positioned far from the main purification unit, then spatial flexibility is improved, but cable length becomes a limiting factor

Engineering Contradiction:

Improvespatial flexibilityVSAvoidcable length

Core Design Contradiction:

Ease of operationVSLength of stationary object

Solution Approach 1:

The patent eliminates the physical cable length constraint by replacing electrical cable connections with wireless electromagnetic communication. The remote dispensing apparatus can be positioned at any distance within wireless signal range from the main purification unit, providing unlimited spatial flexibility compared to cable-based systems.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Reliability

If electrical cables are used for communication, then stable connection is achieved, but electrical noise interferes with adjacent noise-sensitive devices

Engineering Contradiction:

Improveconnection stabilityVSAvoidelectrical noise

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent replaces electrical cable-based communication with wireless electromagnetic communication, thereby eliminating the generation of electrical noise that interferes with adjacent sensitive devices. The wireless system transmits signals through electromagnetic waves without creating the electromagnetic interference associated with wired electrical connections.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
