Electrostatic Spray Gun Probe Mounting Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrostatic spray guns experience current leaks at assembly joints, posing a shock hazard to users, and existing mounting configurations do not effectively retain the charging probe in a home position during operation.
Innovation Solution
A mounting configuration for an electrostatic spray gun that includes a probe with a non-conductive body encasing a conductive element, a probe mount with a non-conductive body, and an elastomeric ring that biases the probe away from the gun, securing it in a home position using a pin and notch mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the probe is mounted on the electrostatic spray gun, then the charging function is enabled, but current leaks occur at the assembly joint creating a shock hazard
Solution Approach 1:
The patent introduces non-conductive bodies (insulating elements) as intermediary components between the conductive probe and the electrostatic spray gun. These insulating elements act as mediators that allow the probe to be mounted on the gun while preventing direct electrical contact, thereby eliminating current leaks at the assembly joint while maintaining the charging function.
2Ease of operation
If a simple mounting configuration is used, then the probe can be easily attached, but the probe cannot be retained in a home position during operation
Solution Approach 1:
The mounting configuration is divided into distinct functional segments: non-conductive bodies for insulation, elastomeric rings for biasing force, pins for positioning, and notches for retention. Each segment performs a specific function, and together they provide both easy mounting capability and reliable probe retention in the home position during operation.
Solution Approach 2:
The elastomeric rings are pre-installed on the probe mount to exert a biasing force that automatically pushes the probe toward the home position. The pins are pre-positioned to engage with the notches, creating a predetermined retention mechanism that ensures the probe remains securely mounted without requiring additional fastening operations.
3Object-affected harmful factors
If non-conductive bodies are used to insulate the user, then shock hazard is reduced, but the mounting structure becomes more complex
Solution Approach 1:
The patent merges multiple functions into the non-conductive bodies: they simultaneously provide electrical insulation to reduce shock hazard, structural support for the probe mounting, and integration with the elastomeric rings and pins to maintain the home position. This consolidation reduces the need for separate insulating components, thereby limiting the increase in overall structural complexity.

Function Achieved in This Case
The described mounting configuration reduces current leaks through the attachment site and retains the probe in a home position during operation, enhancing user safety and operational efficiency.
Implementation Method 1
The first elastomeric ring is configured to exert a force on the first non-conductive body to bias the first non-conductive body away from the electrostatic spray gun such that the probe is secured in a home position

AI summary
A mounting configuration for an electrostatic spray gun includes a probe having a first non-conductive body encasing a first conductive element and a probe mount extending from the electrostatic spray gun with a second non-conductive body encasing a second conductive element. The mounting configuration includes a first elastomeric ring disposed about the second non-conductive body and configured to interface with the first non-conductive body. The first elastomeric ring is configured to exert a force on the first non-conductive body to bias the first non-conductive body away from the electrostatic spray gun such that the probe is secured in a home position. A pin extending from one of the first non-conductive body and the second non-conductive body is seated in a notch formed in the other one of the first non-conductive body and the second non-conductive body
