Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gun barrel cleaning apparatuses require significant time to replace worn-out cleaning means like brushes or non-woven fabrics, making them unsuitable for rapid cleaning.
Innovation Solution
An automatic cleaning apparatus with a rotating cleaning unit featuring an internal gear section, connector section, cleaning section, engaging section, and fastening section, allowing for fast detachable and replaceable brushes or non-woven fabrics using a rotary fitting structure and elastic springs for maintaining cleaning force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cleaning means (brushes or non-woven fabrics) are attached to the cleaning unit, then cleaning function is provided, but replacement time is long due to wear
Solution Approach 1:
The cleaning unit is divided into separable components: the cleaning means (brushes or non-woven fabrics) can be detached from the cleaning unit body. This segmentation allows the cleaning means to be replaced independently without replacing the entire cleaning unit, thereby reducing replacement time while maintaining cleaning function.
Solution Approach 2:
A rotary coupling mechanism is introduced between the cleaning means and the cleaning unit body, allowing dynamic attachment and detachment. The cleaning means can be quickly rotated and coupled or decoupled from the cleaning unit, enabling rapid replacement compared to static conventional attachments.
2Reliability
If cleaning means are frequently replaced due to wear, then cleaning effectiveness is maintained, but operational efficiency decreases
Solution Approach 1:
The cleaning means are designed with a predetermined coupling structure that allows for quick attachment and detachment. Before replacement is needed, the new cleaning means can be pre-prepared with the coupling mechanism, enabling immediate installation without complex assembly procedures, thus maintaining cleaning effectiveness while minimizing downtime.
Solution Approach 2:
The worn cleaning means are quickly discarded through the rotary detachment mechanism, and new cleaning means are immediately installed. This efficient discarding and recovering process maintains cleaning effectiveness without significantly impacting operational efficiency.
3Loss of time
If a detachable cleaning unit is used, then replacement speed is improved, but structural complexity increases
Solution Approach 1:
The coupling and decoupling functions are merged into a single rotary mechanism. By combining these functions in one motion, the structure remains relatively simple while achieving fast replacement. The rotary mechanism integrates the attachment and detachment operations, avoiding the need for separate complex coupling and decoupling systems.
Solution Approach 2:
The rotary coupling mechanism serves multiple functions: it provides the attachment interface, enables quick detachment, and maintains structural integrity. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in structural complexity while achieving fast replacement.
