Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices face challenges in maintaining the alignment of nozzles over the service life due to material fatigue and mechanical influences, leading to inconsistent application of cleaning fluids in hospital and commercial settings.
Innovation Solution
A cleaning device design featuring a nozzle unit that penetrates a bore in the cleaning chamber wall, connected via a twist-proof connection element, ensuring stable alignment through a key-lock mechanism or snap lock assembly, preventing rotational movement and maintaining precise nozzle positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If nozzles are aligned using traditional threaded connections with lock nuts, then initial alignment can be achieved, but alignment stability deteriorates over service life due to material fatigue and mechanical influences
Solution Approach 1:
The nozzle connection is divided into two functional parts: a threaded connection element for initial alignment and positioning, and a separate locking mechanism (snap lock or bayonet connection) for maintaining alignment stability. This segmentation allows each component to perform its specific function optimally without compromising the other.
Solution Approach 2:
The alignment of the nozzle is performed in advance during the assembly process using the threaded connection element, which allows for precise positioning. Once aligned, the locking mechanism secures this pre-established alignment, preventing any subsequent shifts during operation.
2Stability of the object's composition
If nozzles are fixed with lock nuts and counter-holders, then alignment can be maintained initially, but alignment changes occur over time due to improper loading and overfilling
Solution Approach 1:
The locking mechanism is designed to accommodate and cushion against mechanical influences such as improper loading and overfilling. The snap lock or bayonet connection provides a robust mechanical interlock that absorbs these disturbances without allowing alignment changes, effectively cushioning the alignment against operational abuses.
3Reliability
If complex alignment mechanisms are used to prevent nozzle misalignment, then alignment stability improves, but device complexity increases
Solution Approach 1:
The alignment and locking functions are merged into a single integrated connection process. The threaded connection element and locking mechanism work together as one unified system, allowing alignment and securing to be achieved in a single assembly operation rather than requiring separate complex adjustment mechanisms.
Solution Approach 2:
The connection mechanism is designed to be self-aligning and self-locking. The geometric features of the connection elements guide the nozzle into proper alignment automatically during assembly, and the locking mechanism secures this alignment without requiring external adjustment or complex control systems.
