Solution Overview

Problem

Existing refrigerator article delivery devices face battery power issues, leading to sudden stops during operation and a poor user experience due to lack of a reliable power source.

Innovation Solution

A method and apparatus for controlling the article delivery device, which includes detecting whether it is in a wireless charging area, charging the device based on its battery power, and only allowing it to move to a target position once the battery reaches a set threshold, ensuring sufficient power for complete delivery and return.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the article delivery device uses a battery-powered wireless design, then the ease of operation and user convenience are improved, but the reliability deteriorates due to battery power issues and sudden stops during operation

Engineering Contradiction:
Improveuser convenienceVSAvoidoperation continuity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary charging actions before the article delivery device needs to operate. The charging area is pre-configured with wireless charging facilities, and the device is automatically charged when returning to this area, ensuring power is replenished before the next delivery task, thus preventing sudden stops during operation

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms where the article delivery device reports its power status to the control system. Based on this feedback, the system determines whether the device needs charging and manages the charging process accordingly, allowing dynamic adjustment of delivery tasks based on actual power levels

Inventive Principle:
Principle #23Feedback

2Productivity

If the article delivery device operates without sufficient power management, then the productivity is improved by continuous operation, but the reliability worsens due to sudden stops and incomplete deliveries

Engineering Contradiction:
Improvedelivery efficiencyVSAvoiddelivery completion
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system checks the battery power level before assigning new delivery tasks. If the power level is sufficient, the device can continue operating; if not, it is directed to charge first. This preliminary power assessment ensures that the device always has enough power to complete its current task and return, preventing sudden stops during delivery operations

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The article delivery device automatically returns to the charging area when its power level drops below a threshold, and the charging process is initiated automatically without external intervention. This self-service mechanism ensures the device maintains sufficient power for continuous productive operation

Inventive Principle:
Principle #25Self-service
