Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional wired communication is used for each component, then data transmission reliability is improved, but device complexity and wiring effort increase significantly

Engineering Contradiction:
Improvedata transmission reliabilityVSAvoidwiring complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Multiple individual data transmission lines for different components are merged into a single wireless communication channel. The surgical table controller communicates with multiple components (position sensors, load cells, safety interlocks) through a unified wireless interface, eliminating the need for separate wired connections for each component while maintaining reliable data transmission.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

Physical wired connections are replaced with wireless communication technology. The patent implements wireless sensors and transmitters that substitute for traditional wired sensors, allowing data transmission without physical cable connections. This reduces wiring complexity while maintaining the reliability needed for surgical safety applications.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Loss of information

If individual data lines are provided for each component, then data transmission accuracy is improved, but ease of manufacture and installation deteriorate

Engineering Contradiction:
Improvedata transmission accuracyVSAvoidinstallation ease
Core Design Contradiction:
Loss of informationVSEase of manufacture

Solution Approach 1:

A universal wireless communication protocol and interface is implemented across all surgical table components. The same wireless transmitter and receiver architecture is used for different component types (position sensors, load cells, safety interlocks), allowing a single multi-functional communication system to handle all data transmission needs without requiring component-specific wiring or configuration.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If wireless communication is used, then ease of operation and safety are improved, but reliability may deteriorate due to potential interference

Engineering Contradiction:
Improvesystem configuration easeVSAvoidcommunication reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The wireless communication system implements feedback mechanisms including acknowledgment packets, retransmission protocols, and signal quality monitoring. The surgical table controller receives confirmation that data packets were successfully received by components, and automatically retransmits data if acknowledgment is not received, ensuring reliable communication despite potential wireless interference.

Inventive Principle:
Principle #23Feedback
