Position arrival switch assembly and automatic cleaning apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic cleaning apparatuses lack a position arrival indication system to confirm if they have returned to a predetermined position for liquid supplementation, which can disrupt the subsequent liquid supplementing process.
Innovation Solution
A position arrival switch assembly is integrated into the automatic cleaning apparatus, comprising a switch component, a button, an elastic arm, and a switch trigger piece. This assembly sends a position arrival signal when the automatic cleaning apparatus returns to a predetermined position, ensuring accurate liquid supplementation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no position arrival indication system is installed, then the device complexity is reduced, but the reliability of liquid supplementation process deteriorates
Solution Approach 1:
The patent implements a feedback mechanism through a switch assembly that detects when the automatic cleaning apparatus arrives at the liquid supplementing station. The switch component provides position feedback to the control system, enabling the apparatus to confirm successful positioning before initiating liquid supplementation, thereby ensuring process reliability without requiring complex external indication systems
Solution Approach 2:
The switch assembly is integrated directly into the liquid storage tank or mobile platform structure, utilizing existing mechanical components (button, elastic arm, trigger piece) to provide self-contained position detection. This self-service approach eliminates the need for separate external indication devices, maintaining simplicity while ensuring reliable position confirmation for liquid supplementation
2Measurement precision
If a position arrival switch assembly is added, then the measurement precision of position detection is improved, but the device complexity increases
Solution Approach 1:
The position detection function is segmented into distinct mechanical components: a button that responds to positional contact, an elastic arm that transmits force, and a switch trigger piece that activates the electrical switch. This segmentation allows each component to perform its specific function with high precision while maintaining simplicity through clear functional separation
Solution Approach 2:
The elastic arm serves as a mechanical intermediary between the button and the switch trigger piece, transmitting positional information through controlled elastic deformation. This intermediary mechanism provides precise position detection by converting mechanical contact into a reliable electrical signal without requiring direct complex linkages
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The position arrival switch assembly effectively indicates the correct positioning of the automatic cleaning apparatus, ensuring reliable and efficient liquid supplementation processes.
Implementation Method 1
an elastic arm, extending in a direction away from the button from, a face of the button that faces the switch component
Implementation Method 2
the switch trigger piece squeezes the elastic component to enable the elastic component to be compressed; and in response to the elastic component being compressed by a predetermined amount, the switch component sends a position arrival signal

AI summary
The position arrival switch assembly is assembled to the automatic cleaning apparatus, and is configured to indicate whether the automatic cleaning apparatus returns to a predetermined position of a pile body. The position arrival switch assembly includes: a switch component; a button, which is configured to move toward the switch component under the action of an external force; an elastic arm, which extends in a direction away from the button from the face of the button that faces the switch component; and a switch trigger piece, which is connected to the end of the elastic arm that is away from the button, wherein the switch component is configured to send a position arrival signal in response to being triggered by the switch trigger piece.
