Tank Cleaning Device Rotational Mounting for Hygienic Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tank cleaning devices do not meet hygienic design standards, as they are not easily dismountable and can have non-cleanable spaces, failing to ensure complete cleanliness.
Innovation Solution
A cleaning device with a connector part, a rotor part, and a holding part that allows for rotational alignment of holding arrangements, enabling secure mounting and easy dismounting through a clip system, and includes chamfered surfaces for rotor part attachment, and adjustable holes for flow control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cleaning device is mounted permanently or with complex securing mechanisms, then the reliability of mounting is improved, but the ease of dismounting and cleaning deteriorates
Solution Approach 1:
The connector part is divided into separate functional elements: a securing element with holding arrangements and a bearing element with corresponding features. This segmentation allows the device to be easily assembled and disassembled while maintaining secure mounting during operation, as each element can be independently positioned and engaged.
Solution Approach 2:
The holding arrangements are designed to transition between different states: during normal operation, the protrusions engage with the recesses to provide secure mounting; during disassembly, the components can be easily separated. This dynamic characteristic allows the same structure to provide both secure mounting and easy dismounting.
2Reliability
If the connector part has complex securing mechanisms, then the reliability of connection is improved, but the device complexity increases
Solution Approach 1:
The connection mechanism is segmented into simple geometric features: protrusions on the bearing element correspond to recesses on the securing element. This segmentation creates a reliable connection through simple, discrete elements rather than complex integrated mechanisms, reducing overall device complexity while maintaining connection reliability.
Solution Approach 2:
Instead of using complex locking mechanisms that require multiple components, the design inverts the approach by using simple protrusion-recess features that naturally engage and disengage. This inverted simplicity reduces device complexity while maintaining reliable connection through the complementary geometric features.
3Stability of the object's composition
If the holding part is securely fixed to the connector part, then the stability of the cleaning device is improved, but the ease of dismounting deteriorates
Solution Approach 1:
The holding part's connection to the connector part is designed to be dynamic rather than static. The protrusions and recesses provide stable engagement during operation, but the same features allow easy disengagement when needed. This dynamic design enables the holding part to be both securely fixed during operation and easily removed for cleaning or maintenance.
4Reliability
If the cleaning device has non-removable components, then the reliability of operation is improved, but the completeness of cleaning deteriorates
Solution Approach 1:
The cleaning device is segmented into removable and non-removable components. The connector part and holding part can be disassembled, allowing complete access to all surfaces for cleaning. This segmentation ensures that no non-cleanable spaces remain while maintaining operational reliability through proper reassembly of the segmented components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device ensures secure and hygienic mounting and dismounting, preventing self-disassembly and allowing for complete cleaning without non-cleanable spaces, while enabling efficient flow control for effective cleaning patterns.
Implementation Method 1
The cleaning head is provided with slots through which the cleaning fluid is guided and the design of the slots creates the rotational movement. The cleaning fluid lays fans in a swirling pattern throughout the tank.
Implementation Method 2
The connector part is connected to the down-pipe by a spring clip.
