Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic cleaning tools, such as vacuum cleaners, require manual operation for navigation and object detection, limiting their autonomous cleaning capabilities.
Innovation Solution
A cleaning device equipped with a detecting unit, navigation control unit, driving unit, floor cleaning unit, judging unit, and robotic arm, which includes a lighting module, imaging module, and matching calculation module to autonomously detect and clean around objects, including transparent ones, by emitting light, capturing images, and determining object types to guide the robotic arm for cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automatic cleaning tools are used, then cleaning efficiency is improved, but manual operation is still required for navigation and object detection
Solution Approach 1:
The cleaning device is equipped with a detecting unit that autonomously detects objects and transparent objects in the environment, a navigation control unit that automatically plans cleaning paths, and a robotic arm that self-adjusts for cleaning different object types without manual intervention
Solution Approach 2:
The patent replaces manual mechanical operation with automated detection systems (lighting module, imaging module), navigation algorithms, and robotic actuation systems that use sensors and control logic instead of human hands and eyes
2Reliability
If the cleaning device detects all objects including transparent ones, then cleaning completeness is improved, but detection difficulty increases
Solution Approach 1:
The patent introduces a lighting module as an intermediary that emits light to illuminate transparent objects, making them visible to the imaging module. The lighting acts as a mediator between the transparent object and the detection system, enabling the camera to capture images of otherwise invisible objects
Solution Approach 2:
The lighting module emits light that causes transparent objects to reflect or refract light differently, creating visible image information that the imaging module can detect. The interaction between light and transparent objects produces detectable optical changes
