Solution Overview

Problem

The existing portable electronic devices lack clarity on the number of procedures that can be completed with the remaining battery power due to varying power consumption based on the content of processing, making it difficult for users to gauge the remaining power effectively.

Innovation Solution

A processing device equipped with a connection unit for image diagnosis catheters, a signal processing unit, a battery, a rotation drive unit, and a processing unit that calculates the number of procedures executable based on the remaining charge, considering power use history, statistical values, and battery deterioration, with options for display and wireless communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the battery indicator shows remaining power as a percentage of full-charge capacity, then the device structure remains simple, but the user cannot clearly understand how many procedures can be completed with the remaining power

Engineering Contradiction:
Improveclarity of remaining power informationVSAvoidpower calculation system complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The system pre-calculates and stores power consumption data for various procedures in a database before actual use. When a procedure is selected, the system retrieves the pre-stored power consumption information and combines it with current battery status to calculate the number of executable procedures, avoiding real-time complex calculations

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors battery charge levels and power consumption history, providing real-time feedback to update the calculation results. The display unit shows the number of executable procedures that is dynamically updated based on current battery status and historical data, ensuring accurate information presentation

Inventive Principle:
Principle #23Feedback

2Measurement precision

If the system calculates the number of executable procedures using detailed power use history and statistical analysis, then the accuracy of remaining power information improves, but the calculation processing time increases

Engineering Contradiction:
Improveaccuracy of remaining power calculationVSAvoidcalculation processing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs statistical analysis on power consumption data in advance and stores calculated values (average, median, mode power consumption) in the database. During actual operation, the system only needs to retrieve these pre-calculated statistical values and perform simple comparisons, dramatically reducing processing time while maintaining high accuracy

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts the calculation method based on available data. When sufficient historical data is available, it uses comprehensive statistical analysis; when data is limited, it uses simpler estimation methods, optimizing the balance between accuracy and processing speed

Inventive Principle:
Principle #15Dynamics
