Solution Overview

Problem

Existing power supply systems for robots using non-contact power supply face challenges in efficiently handling errors such as temperature and power errors during operation, which can disrupt normal power supply and require user intervention, without providing clear and timely notifications to the user.

Innovation Solution

A power supply system that includes an indicator lamp and a processor for executing retry processing when errors occur, maintaining a consistent display manner for temperature errors during retry processing to avoid immediate user notification, and providing distinct notification patterns for different error types to inform the user of the need for action.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the indicator lamp display is changed during retry processing to notify the user of an error, then the user is informed of the error state, but the user experience is degraded due to unnecessary alarm for recoverable errors

Engineering Contradiction:

Improveerror notification accuracyVSAvoiduser experience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent segments error handling into two distinct phases: retry processing phase and error confirmation phase. During retry processing, the indicator lamp maintains normal display to avoid alarming the user, while after retry completion, it switches to error notification display. This temporal segmentation resolves the contradiction by providing accurate error notification only when appropriate.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary retry processing before notifying the user of the error. By attempting to recover from the error state first and only notifying the user after retry completion, the system preliminarily handles recoverable errors silently, improving user experience while maintaining reliability through subsequent accurate notification when needed.

Inventive Principle:

Principle #10Preliminary action

2Loss of information

If the system immediately notifies the user of all errors during non-contact power supply, then the user is informed of all error states, but the productivity is reduced due to frequent user intervention for recoverable errors

Engineering Contradiction:

Improveerror information completenessVSAvoidpower supply continuity

Core Design Contradiction:

Loss of informationVSProductivity

Solution Approach 1:

The system implements self-service error handling by automatically performing retry processing for temperature errors without requiring immediate user intervention. The error information is preserved and communicated after retry completion, while the system independently attempts to resolve the issue, thereby maintaining productivity while ensuring complete error information is eventually conveyed to the user.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system performs preliminary retry processing before user notification to determine if the error is recoverable. This preliminary action filters out transient errors that resolve automatically, ensuring that users are only notified of persistent errors that require intervention, thus maintaining productivity while preserving complete error information for cases that matter.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If the indicator lamp maintains consistent display during retry processing, then the user experience is improved by avoiding unnecessary alarm, but the measurement precision of error state is reduced

Engineering Contradiction:

Improveuser experienceVSAvoiderror state indication

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The patent segments the indicator lamp's function into two modes: normal indication mode during retry processing and error notification mode after retry completion. This segmentation allows the lamp to maintain consistent display (improving user experience) during the uncertain retry phase, while providing precise error state indication in the subsequent notification phase when the error state is confirmed.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The indicator lamp dynamically switches between different display modes based on the processing phase. During retry processing, it maintains normal display dynamically to avoid alarming users, then transitions to error notification display after retry completion, providing precise error state indication only when the state is certain and actionable.

Inventive Principle:

Principle #15Dynamics

AI summary

A power supply system includes: an indicator lamp; and at least one processor. The at least one processor executes retry processing of stopping and then restarting non-contact power supply in a case where an error occurs during the non-contact power supply performed on a robot. The at least one processor maintains a display manner of the indicator lamp during execution of the retry processing as a first manner same as a manner when the error does not occur, in a case where a state of the non-contact power supply is notified by a display manner of the indicator lamp and the occurring error corresponds to an error of a first classification.
