Washing Machine Drum Water Balancing for Leak-Proof Vibration Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Washing machines experience vibrations and reduced spin-drying performance due to uneven laundry distribution during high-speed rotation, leading to noise and machine wear, which existing solutions like adding weights or liquid fail to fully address effectively.
Innovation Solution
A washing machine design featuring a cylindrical stationary protrusion on the tub with a rotating cylindrical housing, an insert between the supply and distribution lines, and sealing elements to deliver water to receptacles on the drum for balancing unbalanced loads, ensuring leak-proof transfer and controlled distribution of water to counteract the imbalance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If liquid is added to the machine for balancing, then vibration is reduced, but leakage and seepage occur during water transfer
Solution Approach 1:
The patent introduces an insert as an intermediary component between the supply line and distribution line. This insert includes sealing elements that prevent direct contact and potential leakage between the rotating and stationary parts, while still enabling water transfer for balancing purposes.
Solution Approach 2:
The patent replaces direct mechanical connection with a sealing-based system. Instead of rigid mechanical joints that may leak, the system uses sealing elements within the insert to create a leak-proof water transfer path from the supply line to the distribution line.
2Stability of the object's composition
If weights are added to increase inertia, then balancing is improved, but transportation of the machine becomes complicated
Solution Approach 1:
The patent uses a dynamic water-based balancing system instead of static weights. Water can be dynamically added or removed from the drum based on the detected imbalance, providing flexible balancing without permanent additions that would affect transportation.
Solution Approach 2:
The patent changes the balancing approach from adding mass (weights) to changing the distribution of existing mass (water). By controlling water distribution in the drum, the system achieves balancing without increasing the overall machine weight or complicating transportation.
3Stability of the object's composition
If water is delivered to receptacles on the drum, then unbalanced load is balanced, but precise leak-proof delivery is difficult to achieve
Solution Approach 1:
The insert serves as a precision intermediary mechanism that ensures accurate water delivery. It includes aligned openings in the sealing elements that precisely connect the supply line outlet to the distribution line inlet, enabling leak-proof and precise water transfer to the correct receptacles.
Solution Approach 2:
The patent uses opening positions in the sealing elements as indicators for precise alignment. The openings are strategically positioned to align with supply and distribution lines at specific rotational positions, ensuring water is delivered to the correct receptacles for effective balancing.
