Surgical Robot Power Selection Circuit for Backup Supply Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgical robots face challenges in maintaining stable power supply due to compact design and limited space, making it difficult to integrate large backup power modules, which can lead to power failures during operations.
Innovation Solution
A power supply protection circuit is introduced, comprising a main power supply module, a backup power supply module, and a selection circuit that automatically selects the appropriate power source based on voltage comparison, ensuring continuous and stable power supply to the surgical robot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large backup power module is integrated into the surgical robot, then power supply stability is improved, but the device size and complexity increase
Solution Approach 1:
The power supply system is segmented into multiple independent power modules (main power module and at least one backup power module), each with smaller individual sizes that can be integrated into the compact surgical robot structure. The selection circuit divides the power selection function into separate components, resolving the contradiction between having backup power capability and maintaining device compactness.
Solution Approach 2:
The selection circuit serves multiple functions: it automatically selects between main and backup power modules, monitors power status, and ensures continuous power supply. This multi-functionality eliminates the need for separate monitoring and switching devices, reducing overall device complexity while maintaining power supply stability.
2Reliability
If a large backup power module is integrated into the surgical robot, then power supply stability is improved, but the available application environment space is reduced
Solution Approach 1:
By dividing the power supply system into multiple smaller modular units (main power module and backup power module(s)), the system achieves the same power stability as a single large module while occupying less total space and fitting better within the compact surgical robot structure.
3Reliability
If automatic power selection is implemented, then power supply stability is improved, but the device complexity increases
Solution Approach 1:
The selection circuit automatically monitors the working status of power modules and switches between them without external intervention. This self-service capability eliminates the need for manual switching mechanisms or complex external control systems, achieving power supply stability through simple automatic operation rather than increased overall system complexity.
