Apparatus for treating laundry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laundry treatment apparatuses experience excessive vibration and deformation due to foam twist or deviation during rotation, leading to potential damage and noise issues, particularly affecting the casing and connection between the cabinet and top cover.
Innovation Solution
The apparatus incorporates a front member and lateral member with bent portions to strengthen the casing, a gap formation unit, and a sub-member to enhance connectivity and reduce vibration, including a hanger connection unit to manage weight distribution and reduce casing vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the motor rotates the inner tank with foam, then the cleaning function is achieved, but excessive vibration occurs causing casing deformation and damage
Solution Approach 1:
A vibration isolation structure is introduced as an intermediary element between the motor/inner tank system and the casing. This structure absorbs and dampens the vibration generated during foam rotation, preventing it from being transmitted to the casing and causing deformation or damage.
Solution Approach 2:
The vibration isolation structure converts the harmful vibration energy into beneficial damping effects. By strategically placing damping materials and isolation elements, the harmful vibrational forces are transformed into controlled energy dissipation, protecting the casing while maintaining the cleaning function.
2Reliability
If the motor operates with foam in the inner tank, then the cleaning process is performed, but excessive noise and vibration occur
Solution Approach 1:
Vibration isolation elements and damping structures serve as intermediaries between the rotating inner tank and the outer casing. These elements absorb and attenuate the vibration and noise generated during operation, reducing the harmful effects while preserving the cleaning process functionality.
Solution Approach 2:
Flexible vibration isolation films and dampening layers are incorporated into the casing structure. These flexible elements absorb vibrational energy and reduce noise transmission, allowing the cleaning process to proceed while minimizing harmful noise and vibration emissions.
3Stability of the object's composition
If a suspension structure is used to support the outer tank, then the tank is properly positioned, but excessive deformation occurs in the upper end portion of the casing due to weight application
Solution Approach 1:
The suspension structure is designed with locally optimized support points and distribution mechanisms. By strategically positioning support elements and distributing the weight load across multiple contact points, the structure maintains proper tank positioning while preventing excessive deformation in the upper end portion of the casing.
Solution Approach 2:
The suspension system distributes the tank weight across multiple spatial dimensions rather than concentrating it at a single point. By using multiple suspension points and distributing the load vertically and horizontally, the structure achieves stable tank positioning without creating excessive localized stress that would deform the casing.
4Reliability
If excessive vibration occurs in the casing, then the cleaning operation continues, but the connection between the cabinet and top cover is released
Solution Approach 1:
Vibration isolation elements are positioned at the connection interfaces between the cabinet and top cover. These intermediary damping elements absorb vibrational forces before they can reach the connection points, maintaining the structural integrity of the assembly while allowing the cleaning operation to continue.
Solution Approach 2:
Vibration damping and isolation elements are pre-installed at critical connection points before the cleaning operation begins. This beforehand cushioning protects the cabinet-top cover connection from excessive vibration forces that would otherwise cause the connection to be released during operation.
