Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning robot systems face issues with low reliability in communication between the cleaning robot and the docking station due to small effective data volume, strict positional requirements, and high error rates in infrared communication.
Innovation Solution
Implementing WiFi communication between the cleaning robot and the docking station, using a combination of short-range communication modes like infrared or Bluetooth for initial pairing and handshake, followed by secure WiFi communication for large data transfer, ensuring continuity through dual-mode communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If infrared communication is used between cleaning robot and docking station, then communication can be established, but communication reliability is low due to small effective data volume, strict positional requirements, and high error rate
Solution Approach 1:
The patent segments the communication process into two distinct phases: initial pairing phase using infrared communication (short-range, high reliability for setup) and data transmission phase using WiFi communication (long-range, high data volume). This segmentation allows each communication mode to operate in its optimal performance zone, resolving the contradiction between reliability and complexity.
Solution Approach 2:
The patent merges two different communication modes (infrared and WiFi) into a unified communication system. The infrared module handles initial pairing and authentication, while the WiFi module handles bulk data transmission. This combination leverages the strengths of both modes to achieve high reliability and high data volume simultaneously.
2Quantity of substance
If infrared communication is used, then communication can be established, but data transmission volume is extremely small
Solution Approach 1:
The patent divides the communication workload by segment: infrared communication handles small-volume authentication and pairing data, while WiFi communication handles large-volume cleaning data transmission. This segmentation resolves the contradiction by assigning appropriate data volumes to appropriate communication channels.
Solution Approach 2:
The docking station is designed with multi-functionality, supporting both infrared communication (for pairing) and WiFi communication (for data transfer). This universal communication capability allows the system to handle both small authentication packets and large cleaning data efficiently.
3Ease of operation
If infrared communication is used, then communication can be established, but strict positional requirements must be met
Solution Approach 1:
The patent segments the docking process into positional alignment (handled by infrared's directional nature) and data exchange (handled by WiFi's omnidirectional capability). This allows the robot to dock without strict positional requirements for data transmission, as WiFi can communicate from multiple angles.
4Reliability
If infrared communication is used, then communication can be established, but error rate is high
Solution Approach 1:
The patent segments the communication protocol into two layers: a simple infrared layer for authentication (with built-in error checking) and a robust WiFi layer for data transmission (with retransmission protocols). This layered approach improves reliability while managing complexity through clear separation of concerns.
