Level adjustable apparatus and method for adjusting level thereof
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washing machines with rotating members face excessive vibration due to tilting or uneven weight distribution, leading to noise, damage, and reduced efficiency, with existing solutions either stopping operation or requiring separate fixing apparatuses without providing precise adjustment methods.
Innovation Solution
A level adjustable apparatus equipped with a level sensor, vibration sensor, and height adjustable supports, where a processor derives and transmits tilt values to adjust the supports motorically to minimize vibration, learned from various operational conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the motor is turned off when vibration increases, then the washing machine is prevented from being damaged or moving from its original position, but the operation of the washing machine is stopped each time the vibration increases
Solution Approach 1:
The system continuously monitors vibration levels through a vibration sensor and provides feedback to the control unit. When excessive vibration is detected, the control unit adjusts the tilt of the cabinet by controlling the height adjustable supports to change the position of the rotating member's rotation axis, thereby reducing vibration while maintaining operation without complete shutdown
Solution Approach 2:
The system dynamically adjusts the tilt of the cabinet during operation by controlling the height of adjustable supports based on real-time vibration feedback. This allows the rotation axis position to be optimized during operation, reducing vibration without requiring complete shutdown and enabling continuous productive operation
2Reliability
If a separate fixing apparatus is used to reduce vibration, then the leveling can be adjusted, but a separate fixing apparatus is required in addition to the washing machine and the user needs to adjust the height using their own judgment
Solution Approach 1:
The leveling adjustment function is merged into the washing machine itself by integrating height adjustable supports directly into the cabinet structure. The control unit combines vibration sensing, tilt sensing, and support adjustment control into a single integrated system, eliminating the need for separate external fixing apparatus
Solution Approach 2:
The washing machine performs self-leveling by automatically sensing its own vibration and tilt conditions through integrated sensors, then autonomously adjusting the height of its own supports through motorized control. This eliminates the need for external apparatus and user judgment, as the system serves itself
3Ease of operation
If the height of the supporting stand is adjusted manually, then the leveling can be changed, but the user needs to adjust the height using their own judgment without guidance on the target state
Solution Approach 1:
The control unit receives feedback from both vibration sensors and tilt sensors to determine the current vibration level and cabinet tilt angle. Based on this feedback, the system calculates the optimal tilt value needed to minimize vibration and communicates this target value to the user through a display or user terminal, providing precise guidance for adjustment
Solution Approach 2:
The manual mechanical adjustment process is replaced with automated motorized adjustment of the height supports. The control unit automatically controls the motors to adjust support heights based on sensor feedback, eliminating the need for manual user judgment while maintaining ease of operation through automatic control
