Flushing Pump Remote Diagnostics via Debug Connection Port
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flushing pumps used in medical procedures, such as endoscopic surgeries, cannot be effectively evaluated or diagnosed for performance, requiring complete disassembly for inspection, which is inefficient and inconvenient.
Innovation Solution
A flushing pump system with a remote controller connection port and processor that allows for remote diagnostics and servicing through a debugging connection point, enabling the output of diagnostic information and remote operation, using a reference voltage level for secure access and a debugging cable for hard-wired diagnostics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the flushing pump is designed without remote diagnostics capability, then the device structure remains simple, but the pump cannot be evaluated or diagnosed for performance without complete disassembly
Solution Approach 1:
A remote controller connection port serves as an intermediary interface between the processor and external debugging devices. This port includes dedicated connection points (debugging connection point, ground connection point) that enable remote diagnostics without requiring physical disassembly of the pump, thus improving ease of diagnostics while adding minimal structural complexity
Solution Approach 2:
The processor is configured to automatically output diagnostic information when it detects a specific signal pattern (reference voltage level) at the debugging connection point. This self-service capability allows the pump to perform self-diagnosis and provide performance evaluation data without requiring manual disassembly or complex external testing equipment
2Loss of information
If the processor outputs diagnostic information continuously, then remote diagnostics are always available, but energy is wasted and unauthorized access may occur
Solution Approach 1:
The processor outputs diagnostic information periodically or on-demand rather than continuously. It activates diagnostic mode only when detecting a specific periodic signal pattern (reference voltage level at debugging connection point), which reduces energy consumption while ensuring diagnostic information is available when needed by authorized personnel
3Ease of operation
If the debugging connection point is always accessible, then diagnostics can be performed at any time, but unauthorized users may access diagnostic information
Solution Approach 1:
The system implements preliminary anti-action by requiring a specific activation condition (reference voltage level signal) before diagnostic mode is entered. This pre-condition acts as a security measure that prevents unauthorized access while maintaining ease of operation for authorized personnel who know how to provide the correct activation signal
