Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional high-pressure rotary nozzles lack the capability to capture and utilize operational data for optimizing their use, leading to decisions based on conjecture rather than actual performance, and they experience overspeeding issues that increase wear and reduce service life.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional rotary nozzles operate at high rotational speeds to maintain cleaning effectiveness, then cleaning efficiency is improved, but wear increases and service life decreases
Solution Approach 1:
The patent applies feedback by using rotation sensors to continuously monitor the rotational speed of the nozzle and providing this information to a control system. The control system processes the rotation data and provides feedback signals to adjust the operational parameters, enabling the system to maintain optimal speed within a target range and prevent excessive wear while preserving cleaning effectiveness.
Solution Approach 2:
The patent implements parameter changes by dynamically adjusting the rotational speed parameter based on monitored conditions. The system varies the rotation speed within an optimal range rather than operating at constant high speed, thereby reducing wear and extending service life while maintaining adequate cleaning performance through controlled parameter variation.
2Device complexity
If operational data is not collected during rotary nozzle use, then device complexity is reduced, but decisions regarding tool choice and operating parameters are based on conjecture rather than actual performance
Solution Approach 1:
The patent applies universality by designing a data logging system that serves multiple functions: it records rotational speed, tracks operational hours, monitors usage patterns, and provides data for both immediate control feedback and long-term performance analysis. This multi-functional approach justifies the added complexity by delivering comprehensive operational insights that inform tool selection, parameter optimization, and maintenance scheduling.
Solution Approach 2:
The system implements self-service by automatically collecting, storing, and analyzing operational data without requiring external intervention. The rotary nozzle assembly autonomously monitors its own performance parameters and generates actionable insights, enabling users to make data-driven decisions about tool choice and operating conditions based on actual rather than conjectured performance.
3Duration of action of stationary object
If rotation speed is reduced to extend service life, then wear is reduced, but cleaning efficiency may be compromised
Solution Approach 1:
The patent applies dynamics by implementing a dynamic speed control system that continuously adjusts rotational speed based on real-time monitoring and feedback. Rather than operating at a fixed reduced speed, the system dynamically modulates speed within an optimal range, adapting to varying cleaning conditions while preventing excessive wear, thereby maintaining cleaning efficiency without sacrificing service life.

AI summary
A nozzle assembly with a data logger. The nozzle apparatus assembly comprises a housing body and a tubular nozzle shaft coupled to a nozzle head. The tubular nozzle shaft and the nozzle head define a portion of a fluid pathway extending from an inlet end of the housing body to a set of directional nozzles. The tubular nozzle shaft and the nozzle head are configured to rotate together in response to a discharge of a pressurized liquid from the set of directional nozzles. A data logger housed within the housing body includes a rotation sensor configured to detect rotation of the tubular nozzle shaft or the nozzle head, a data storage device configured to store rotation data captured by the rotation sensor or rotational speed data calculated from the rotation data and time data, and a communications interface configured to transmit the stored data to a remote computing device.
