Solution Overview

Problem

Surgical microscope systems face challenges in maintaining balance, especially when accessories are added or components are adjusted, leading to potential sudden movements due to imbalance, which can surprise surgeons and compromise surgical precision.

Innovation Solution

The implementation of sensors to monitor the balance of the surgical microscope system, providing warnings to users and overriding brake releases to prevent sudden movements, using a processing module that integrates with various output modules for visual, audio, or haptic feedback, and optionally activating an auto-balancing system to correct imbalances.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If automatic balancing functionality is implemented, then balancing effort and time are reduced, but sudden movements may occur when imbalance is not detected in time

Engineering Contradiction:
Improvebalancing operationVSAvoidsystem stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary detection of imbalance conditions before they result in sudden movements. Sensors continuously monitor balance parameters and trigger warnings or brake overrides in advance, preventing the harmful effect of sudden microscope movements while maintaining ease of operation through automatic monitoring.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements continuous feedback through sensors that monitor balance conditions and provide real-time information to the control system. This feedback loop enables the system to detect impending imbalances and respond with warnings or brake overrides, ensuring system stability while maintaining automatic operation.

Inventive Principle:
Principle #23Feedback

2Reliability

If sensors and monitoring systems are added, then system stability is improved, but device complexity increases

Engineering Contradiction:
Improvebalance monitoringVSAvoidsystem structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The sensor system is integrated into the existing microscope stand structure, allowing the same components to serve multiple functions: structural support, balance monitoring, and automatic correction. This multi-functionality reduces the need for separate dedicated monitoring components, thereby limiting the increase in device complexity.

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

Solution Approach 2:

The monitoring and control functions are merged with the existing brake and balancing systems. The processing module integrates sensor data with the brake control system, combining multiple functions into a unified control architecture that reduces overall system complexity compared to having separate independent systems.

Inventive Principle:
Principle #5Merging (Combining)
