Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual cleaning of buckets used in industries like the floral industry is inefficient and prone to incomplete cleaning, leading to potential contamination and reduced freshness of flowers due to bacterial growth, which affects customer satisfaction and florist reputation.
Innovation Solution
An automated bucket cleaning system comprising a cleaning mixture dispenser, a washing station with a rotating brush, and a rinsing fountain, controlled by foot-operated valves, to ensure thorough cleaning and rinsing of buckets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual cleaning process is used, then workers can clean buckets, but the cleaning process is time-consuming and tedious, taking 2-5 hours to clean 100-500 buckets
Solution Approach 1:
The patent replaces manual mechanical cleaning actions with an automated mechanical system consisting of a rotating brush mechanism, water delivery system, and suction system. The brush rotates automatically to scrub bucket interiors while water is delivered and suction removes debris, eliminating the need for manual scrubbing and significantly increasing cleaning productivity.
Solution Approach 2:
The cleaning system performs self-service through automated operation where the machine handles water delivery, brush rotation, and debris removal without continuous human intervention. The system can operate autonomously to clean multiple buckets in sequence, reducing the time workers spend on this tedious task.
2Reliability
If workers manually clean buckets thoroughly, then contamination is prevented, but the tedious nature of the work causes workers to skip corners and incompletely clean some buckets
Solution Approach 1:
The automated mechanical system ensures consistent and thorough cleaning by mechanically rotating brushes that contact all interior surfaces of buckets uniformly. The system eliminates human error and variability, ensuring each bucket receives the same level of cleaning attention without workers skipping corners due to fatigue or boredom.
Solution Approach 2:
The system incorporates feedback mechanisms where the suction system and water delivery are coordinated to ensure proper cleaning. The automated system can detect and respond to cleaning needs, maintaining consistent thoroughness across all buckets without requiring worker motivation or attention.
3Productivity
If buckets are not thoroughly cleaned, then cleaning time is reduced, but bacteria grow in the water and harm new flowers, causing unpleasant odors and reputation issues
Solution Approach 1:
The automated cleaning system ensures thorough removal of organic matter and bacteria from bucket interiors through consistent mechanical brushing and water delivery. This eliminates the risk of residual contamination that would occur with rushed manual cleaning, preventing bacterial growth in subsequent water fills while maintaining high cleaning efficiency.
Solution Approach 2:
The system maintains continuous cleaning action with rotating brushes and continuous water flow, ensuring no areas are missed and all surfaces are thoroughly cleaned. This continuous action prevents bacterial contamination more effectively than intermittent manual cleaning while maintaining high productivity.
4Productivity
If an automated cleaning system is implemented, then cleaning efficiency and thoroughness are increased, but the system complexity and initial cost increase
Solution Approach 1:
The automated cleaning system is divided into separate functional modules: a brush mechanism for scrubbing, a water delivery system with valves and hoses, and a suction system. This segmentation allows each component to be independently designed, maintained, and replaced, reducing overall system complexity while maintaining high cleaning efficiency.
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 system significantly increases cleaning efficiency and thoroughness, reducing manual labor time and ensuring buckets are thoroughly cleaned, thereby maintaining flower freshness and preventing bacterial contamination.
Implementation Method 1
a washing station having a brush for abrading an inside surface of the bucket and for spreading the cleaning mixture across the inside surface of the bucket
Implementation Method 2
a rinsing fountain for spraying water over the inside surface of the bucket to rinse of the cleaning mixture when the bucket is turned upside down over the rinsing fountain

AI summary
A system for cleaning buckets includes a cleaning mixture dispenser that includes a source of flowing water interfaced to a foot-operated valve such that operation of the foot-operated valve causes water to flow mixed with a cleaning fluid for placement into the bucket. A washing station has a brush for abrading an inside surface of the bucket that is interfaced to a motor that is controlled by a foot-operated switch. A rinsing fountain for spraying water over the inside surface of the bucket is interfaced to the source of flowing water through a second foot-operated valve such that operation of the second foot-operated valve causes water to flow through a rinse fountain feed tube and out of the rinse fountain head through orifices in the rinse fountain head for spraying onto the inside surfaces of the bucket that is turned upside down over the rinse fountain head.
