Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a transponder is embedded in a belt for RF communication, then communication capability is added, but the transponder is prone to damage and failure under high operating conditions

Engineering Contradiction:

ImproveRF communication capabilityVSAvoidtransponder durability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The RF communication device is segmented into separate functional components: a protective housing, an electronic module, and inductively coupled conductive wires. This segmentation allows each component to be optimized independently, with the housing providing mechanical protection while the electronic module and wires maintain RF communication functionality without direct electrical contact that could cause failure under high operating conditions.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Inductively coupled conductive wires serve as an intermediary between the electronic module and the external RF environment. These wires transfer RF energy and signals without direct electrical contact, providing a reliable coupling mechanism that avoids the damage and failure issues associated with direct electrical connections under high operating conditions.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If the belt operates under high speed and high pressure conditions, then productivity increases, but the transponder is more likely to fail

Engineering Contradiction:

Improvebelt operating speedVSAvoidtransponder reliability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The protective housing is designed beforehand to cushion and absorb mechanical stresses, impacts, and vibrations that the belt may encounter during high-speed and high-pressure operation. This pre-established protection prevents the transponder components from failing under extreme operating conditions while maintaining productivity.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The protective housing is constructed as a flexible shell that can withstand high operating conditions while protecting the internal electronic components. This flexible enclosure maintains the integrity of the transponder during high-speed belt operation and pressure variations, preventing failure while allowing the belt to maintain high productivity.

Inventive Principle:

Principle #30Flexible shells and thin films
