Cleaning Module Elastic Suspension for Motor Weight Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices suffer from weight imbalance on the left and right ends of the garbage cleaning module due to the motor arrangement, affecting cleaning performance.
Innovation Solution
The cleaning module is equipped with two hanging points, one high and one low, with the elastic member suspended from both ends, allowing for easy repositioning and assembly by detaching and reattaching to the bottom housing, balancing the weight distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a motor is arranged at an end of the garbage cleaning module to drive the roller brush, then the cleaning function is achieved, but weight imbalance occurs on the left and right ends
Solution Approach 1:
The patent applies the counterweight principle by adding a weight balancing assembly that includes a counterweight block and elastic member. The counterweight block is positioned on the opposite side of the motor to offset the weight imbalance, while the elastic member provides flexible connection to accommodate movement while maintaining balance. This directly addresses the weight imbalance caused by the motor's asymmetric positioning.
2Power
If the cleaning module is designed with motor at one end, then driving function is achieved, but assembly complexity increases due to weight balancing requirements
Solution Approach 1:
The patent segments the cleaning module into distinct functional components: the motor assembly, the roller brush assembly, and the weight balancing assembly. Each component can be independently assembled and adjusted. The weight balancing assembly is further segmented into a counterweight block and an elastic member, allowing for modular assembly that reduces overall complexity while maintaining the driving function.
3Stability of the object's composition
If elastic member is suspended from bottom housing through hanging points, then weight balance is achieved, but assembly difficulty increases due to repositioning operations
Solution Approach 1:
The patent implements preliminary action by pre-positioning the hanging points on the cleaning module and bottom housing before final assembly. The first and second hanging points are predetermined locations that guide the suspension of the elastic member. This preliminary positioning simplifies the assembly process by reducing the need for complex repositioning operations, as the components are already aligned for optimal weight balance.
