Solution Overview

Problem

Current sweepers face challenges with complex calculations requiring multiple processors, leading to increased costs and manufacturing difficulties, and experience inaccurate control due to low communication speed, poor anti-interference, and high delay in 3G/4G networks.

Innovation Solution

Integration of a 5G communication module in the sweeper allows direct communication with a server, offloading complex calculations and reducing the need for multiple processors, while utilizing the 5G network's high speed and low latency to improve control accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If multiple processors are integrated in the sweeper for complex calculations, then the calculation capability is improved, but the manufacturing cost and difficulty increase

Engineering Contradiction:
Improvecalculation capabilityVSAvoidmanufacturing cost and difficulty
Core Design Contradiction:
Extent of automationVSEase of manufacture

Solution Approach 1:

The patent extracts the complex calculation functions from the sweeper device and relocates them to a cloud server. The sweeper only retains basic control and communication functions, while ground material detection, obstacle detection, and path planning calculations are performed remotely on the server, thus reducing the hardware complexity and manufacturing difficulty of the sweeper while maintaining high calculation capability

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a cloud server as an intermediary between the sweeper and the user/environment. The server acts as a remote brain that receives sensor data from the sweeper, performs complex calculations for navigation and obstacle avoidance, and sends control commands back to the sweeper, thereby separating the computation-intensive tasks from the physical device

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If 3G/4G networks are used for communication, then the sweeper can communicate with the outside, but the communication speed is low, anti-interference is poor, and delay is high

Engineering Contradiction:
Improvecommunication capabilityVSAvoidcommunication speed
Core Design Contradiction:
Ease of operationVSSpeed

Solution Approach 1:

The patent changes the communication parameter by upgrading from 3G/4G networks to 5G network. This parameter change brings significant improvements in communication speed, reduces latency, and enhances anti-interference capabilities, enabling real-time or near-real-time communication between the sweeper and the cloud server for accurate and responsive control

Inventive Principle:
Principle #35Parameter changes

3Reliability

If 3G/4G networks are used for communication, then the sweeper can connect to the network, but the delay is high causing inaccurate control

Engineering Contradiction:
Improvecontrol accuracyVSAvoidcommunication delay
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent changes the network communication parameter to 5G, which reduces communication delay and latency. This time loss reduction ensures that control commands are transmitted and executed in real-time, improving the reliability and accuracy of sweeper control while maintaining network connectivity

Inventive Principle:
Principle #35Parameter changes
