Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of autonomous cleaning devices, particularly with integrated sensing modules like laser distance sensors, leads to installation inaccuracies and maintenance difficulties due to long dimensional chains and the need for disassembly of entire devices for component replacement.
Innovation Solution
A modular design for the autonomous cleaning device where the sensing module, drive module, and cleaning module are detachably assembled to the device body, allowing for separate installation and maintenance without disassembling the entire device, with a protective upper housing and cover to ensure precision and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the autonomous cleaning device integrates multiple functional modules (sensing module, drive module, cleaning module) into a single device body, then the functionality and intelligence of the device is improved, but the internal structure becomes more complex and maintenance difficulty increases
Solution Approach 1:
The autonomous cleaning device is divided into multiple independent functional modules: sensing module, drive module, and cleaning module. Each module can be detached separately from the device body through corresponding mounting structures, allowing independent maintenance and replacement without disassembling the entire device.
2Quantity of substance
If the sensing module is installed with a long dimensional chain, then the device can accommodate multiple components, but the installation accuracy of the sensing module decreases
Solution Approach 1:
The sensing module is designed as a separate detachable unit with its own mounting structure that directly connects to the device body. This segmented approach shortens the dimensional chain for sensing module installation, improving positioning accuracy while still allowing multiple sensing components to be integrated within the module.
3Ease of repair
If the entire device needs to be disassembled for component replacement, then all components can be accessed, but the maintenance time and difficulty increase significantly
Solution Approach 1:
Each functional module (sensing module, drive module, cleaning module) is designed with detachable mounting structures that allow individual modules to be removed from the device body independently. This enables maintenance personnel to access and replace specific components without disassembling the entire device, significantly reducing maintenance time and complexity.
4Ease of operation
If functional modules are detachably assembled, then maintenance is simplified and installation accuracy is improved, but the device structure becomes more complex
Solution Approach 1:
The device employs standardized detachable mounting structures for each functional module, where each module has corresponding mounting holes and fixing mechanisms. While this creates multiple connection points, the standardized design simplifies the assembly process and improves maintainability compared to a fully integrated structure.
