Problem

Long, fragile wires used to connect sensors to control devices are prone to damage and signal interference, affecting measurement quality and requiring frequent replacement, especially in industrial settings where logistics demand extended cable lengths.

Innovation Solution

An electronic control device with a bayonet circular military connector and integrated radio transmission capabilities, including a programmable electronic board with digital-analog conversion and power supply, allowing for wireless communication of sensor data directly to a central equipment while maintaining wired operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If long wires are used to connect sensors to control devices for logistics management, then the spatial flexibility is improved, but the signal quality and reliability deteriorate due to interference and damage

Engineering Contradiction:

Improvespatial flexibilityVSAvoidsignal quality

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent replaces the mechanical wire connection system with a wireless communication system. The sensor node contains a radio frequency module that transmits sensor data wirelessly to the control device, eliminating the need for long physical wires. This substitution resolves the contradiction by maintaining spatial flexibility (no wires to constrain movement) while improving signal quality (wireless transmission avoids wire-related interference and damage issues).

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent extracts the signal transmission function from the physical wire medium and transfers it to the wireless radio frequency communication module. By removing the wire from the system, the harmful effects of wire-related signal degradation, damage, and interference are eliminated, while the spatial flexibility benefit is preserved through wireless operation.

Inventive Principle:

Principle #2Taking out (Extraction)

2Ease of operation

If long wires are used for sensor connections, then spatial flexibility is improved, but the frequency of wire damage and replacement increases

Engineering Contradiction:

Improvespatial flexibilityVSAvoidwire replacement frequency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The patent replaces the mechanical wire connection system with a wireless communication system. The sensor node contains a radio frequency module that transmits sensor data wirelessly to the control device, eliminating the need for long physical wires. This substitution resolves the contradiction by maintaining spatial flexibility (no wires to constrain movement) while improving signal quality (wireless transmission avoids wire-related interference and damage issues).

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent eliminates the need for durable, replaceable wires by using wireless communication. Instead of dealing with short-living wires that require frequent replacement, the system uses a wireless transmission approach where the sensor node itself is the permanent component, and no consumable connection medium is needed.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Adaptability or versatility

If connectors are frequently connected and disconnected for wire replacement, then adaptability is improved, but the wire and connector damage increases

Engineering Contradiction:

Improveconnector flexibilityVSAvoidconnection stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent replaces the mechanical connector system with wireless radio frequency communication. The sensor node transmits data wirelessly without requiring physical connectors to be connected or disconnected. This eliminates the wear and damage caused by repeated connector operations while maintaining adaptability through software-based configuration and wireless pairing capabilities.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
