Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lifting mechanisms for cleaning assemblies in cleaners, such as sweeping robots, require additional motors and occupy large structural space, increasing cost and system complexity, and necessitate manual switching between modes.
Innovation Solution
A lifting apparatus that utilizes a roller driven by a motor, with a flange interacting with a boss on the cleaner's body, allowing passive lifting and reduced space occupation, using the roller's rotation to switch between operating and receiving positions without extra parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional lifting mechanism with additional motor is used, then the lifting function is reliable, but the device complexity and space occupation increase
Solution Approach 1:
The motor's output shaft serves dual functions: directly driving the roller for cleaning operation and, through the boss-flange interaction, enabling passive lifting of the cleaning assembly. This multi-functionality eliminates the need for a separate lifting motor, reducing device complexity while maintaining lifting reliability.
Solution Approach 2:
The lifting mechanism utilizes the motor's own rotational motion and the mechanical interaction between the boss and flange to achieve passive lifting. The system serves itself by converting the motor's operational rotation into lifting action without requiring external power or additional actuators.
2Reliability
If a conventional lifting mechanism with additional motor is used, then the lifting function is reliable, but the cost increases
Solution Approach 1:
The motor performs both cleaning and lifting functions through its single output shaft, eliminating the need for a second motor. This reduces component count, manufacturing complexity, and overall system cost while maintaining reliable lifting functionality.
Solution Approach 2:
The lifting function is merged with the motor's existing structure by utilizing the output shaft and its interaction with the boss-flange mechanism. This consolidation eliminates redundant components and reduces manufacturing costs.
3Reliability
If a conventional lifting mechanism is used, then the lifting capability is sufficient, but the space occupation is large
Solution Approach 1:
The lifting mechanism is nested within the existing motor structure, utilizing the output shaft and integrating the boss-flange interaction directly into the motor's operational space. This nesting approach minimizes additional space requirements while maintaining full lifting capability.
Solution Approach 2:
The motor's output shaft serves dual purposes, eliminating the need for separate lifting mechanism space. The same rotational component enables both cleaning and lifting functions, significantly reducing the overall space occupied by the lifting system.
4Device complexity
If manual switching between modes is required, then the control is simple, but the ease of operation decreases
Solution Approach 1:
The cleaning assembly automatically switches between operating and receiving positions through the passive lifting mechanism driven by the motor's rotation. The system self-regulates its position based on operational needs, eliminating manual intervention and improving ease of operation.
Solution Approach 2:
The cleaning assembly dynamically adjusts its position (operating or receiving) based on the motor's rotational state and the boss-flange interaction. This dynamic automatic switching replaces static manual mode selection, enhancing operational convenience.
