Solution Overview

Problem

Current operating table control systems fail to recognize attached components accurately, limiting the usable range of movement due to worst-case configuration assumptions, which can lead to collisions and restricted functionality.

Innovation Solution

A component with a communication module and detection device that autonomously transmits information about itself and attached components, using a switch to activate the communication module and a low-energy transmission unit, allowing the control system to determine the exact configuration and range of movement without collisions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the control system uses worst-case configuration assumptions to ensure safety, then collision avoidance is guaranteed, but the usable range of movement is restricted

Engineering Contradiction:
Improvecollision avoidanceVSAvoidusable range of movement
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements feedback by using detection devices (switches) to sense the actual configuration of attached components and transmitting this information back to the control system. This allows the control system to adjust the virtual collision-free movement space based on real-time component detection rather than relying on static worst-case assumptions, thereby expanding the usable range of movement while maintaining collision avoidance.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent applies preliminary action by pre-defining multiple virtual collision-free movement spaces corresponding to different component configurations. Before the operating table is used, the control system determines which configuration is actually present and selects the appropriate pre-calculated movement space, enabling optimal range of motion from the start without needing to restrict movement based on unknown configurations.

Inventive Principle:
Principle #10Preliminary action

2Ease of manufacture

If passive radio identification elements are used for component detection, then procurement costs are reduced, but the detection reliability may be insufficient

Engineering Contradiction:
Improveprocurement costsVSAvoiddetection reliability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent merges multiple functions into a single integrated system: the detection device (switch) physically integrated with the component, the communication module for data transmission, and the power supply device. This integration ensures reliable detection through direct physical contact (switch activation) while keeping costs low by using simple, proven technologies rather than complex active RFID systems.

Inventive Principle:
Principle #5Merging (Combining)
