Injector Nozzle Tool-Free Maintenance via External Grip Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing injector nozzles require complex handling and tool usage for maintenance, especially in agricultural applications where protective gloves hinder tool manipulation, making maintenance difficult and time-consuming.
Innovation Solution
The design incorporates a housing with through-openings and a gripping section accessible from the outside, allowing the injector component to be removed without tools by engaging a human finger or tweezers, and featuring corrugations for improved grip and actuating webs for symmetrical force application, enabling easy removal and reinstallation, even with gloved hands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the injector component is designed to be removable for maintenance, then ease of repair is improved, but device complexity increases due to additional handling mechanisms
Solution Approach 1:
The injector component is segmented from the housing as a separate removable unit. The housing contains through-openings that allow access to the injector component's handle section, enabling independent removal and maintenance of the injector component without disassembling the entire device.
Solution Approach 2:
The injector component is designed with an externally accessible handle section that allows users to remove and reinstall it using only their hands (even with protective gloves). This self-service design eliminates the need for tools or complex mechanical fastening mechanisms, resolving the contradiction by maintaining simplicity while enabling easy repair.
2Reliability
If protective gloves are worn during operation, then safety is improved, but ease of operation deteriorates due to difficulty in manipulating tools
Solution Approach 1:
The injector component features a handle section accessible through through-openings in the housing, allowing direct manual manipulation for removal and installation. This design enables users wearing protective gloves to perform maintenance without requiring tools, thus maintaining safety while preserving ease of operation.
Solution Approach 2:
The handle section is positioned in a different spatial dimension - accessible through the housing wall via through-openings rather than requiring access from the front or top. This dimensional repositioning allows gloved hands to grasp and manipulate the injector component easily, resolving the contradiction between safety (glove wear) and ease of operation.
3Ease of operation
If the injector component is accessible from the outside, then ease of operation is improved, but device complexity increases due to additional housing features
Solution Approach 1:
The housing is segmented with through-openings that create access pathways to the injector component's handle section. This segmentation allows external access without requiring complex mechanical interfaces, maintaining structural simplicity while improving ease of operation.
Solution Approach 2:
The handle section of the injector component is extracted to be accessible from the outside of the housing through the through-openings. This extraction allows users to grasp and manipulate the injector component externally without adding complex fastening or release mechanisms to the housing structure.
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
This design simplifies maintenance by allowing tool-free removal and reinstallation of the injector component, reducing operational complexity and time, especially in agricultural settings where glove use is common, enhancing handling efficiency and ease of use.
Implementation Method 1
The injector component is intended for sucking in ambient air. A jet of water is directed a little way through the environment in order to entrain air as a result.
