Removable Pressure Gauge Module for Ergonomic Paint Spray Gun
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manually operated paint spray guns with digital pressure gauges are complex to clean and maintain, as the gauge's removal often compromises the ergonomic and aesthetic design of the handle, and can hinder the gun's operation.
Innovation Solution
A digital pressure gauge module is integrated into the handle's dorsal area, allowing easy angular disconnection and reconnection without altering the handle's configuration, featuring mechanical and magnetic locking, and a safety stop activated by compressed air to ensure secure operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pressure gauge is integrated into the handle in a fixed manner, then the handle maintains its ergonomic and aesthetic configuration, but the gauge cannot be easily removed for cleaning operations
Solution Approach 1:
The pressure gauge is divided into a separable module that can be detached from the handle. This module includes the gauge housing and is connected to the handle body through a quick-release mechanism, allowing the gauge to be segmented from the main body for easy removal during cleaning operations while maintaining the overall handle structure integrity.
Solution Approach 2:
The pressure gauge is extracted as a removable component from the handle assembly. The gauge module can be completely separated from the handle body through a quick-release mechanism, enabling easy access for cleaning operations without compromising the permanent structural integrity of the handle itself.
2Ease of operation
If the pressure gauge is made separable from the handle, then it can be easily removed for cleaning, but the removal process becomes complex and time-consuming
Solution Approach 1:
The connection between the pressure gauge module and handle body is made dynamic rather than static. A quick-release mechanism with spring-loaded latches allows the gauge to be rapidly detached and reattached, transforming the removal process from a complex multi-step operation to a simple snap-action movement that can be completed in seconds.
Solution Approach 2:
The traditional threaded or bayonet connection mechanisms are replaced with a pneumatic or magnetic quick-release system. Compressed air pressure or magnetic attraction/repulsion forces are used to secure and release the gauge module, eliminating the need for manual threading or complex mechanical disengagement procedures.
3Object-affected harmful factors
If the pressure gauge is separated from the handle, then cleaning access is improved, but the ergonomic grip and aesthetic appearance are compromised
Solution Approach 1:
The pressure gauge module is designed as a standalone unit that replicates the essential functional appearance when attached to the handle. The module's housing and mounting structure are shaped to match the handle's ergonomic contours, so that whether attached or removed, the overall aesthetic and grip characteristics remain unchanged.
Solution Approach 2:
The separable module is designed with specific local characteristics that match the handle's ergonomic requirements only in the areas where contact occurs. The mounting interface and surrounding housing are shaped to maintain the handle's grip profile, while the internal gauge components can be completely accessed and removed for cleaning without affecting the external ergonomic configuration.
4Ease of repair
If the pressure gauge is made removable, then maintenance is simplified, but the structural integrity and reliability of the handle are reduced
Solution Approach 1:
The handle assembly is segmented into permanent structural components and removable functional modules. The handle body itself remains intact and permanent, while only the pressure gauge module is made separable. This segmentation allows maintenance of the gauge without compromising the structural integrity of the handle's load-bearing and grip-critical structures.
Solution Approach 2:
Only the non-structural pressure gauge components are extracted as removable elements. The handle's structural framework, grip surfaces, and critical mounting points remain permanently integrated, ensuring that the act of removing the gauge for maintenance does not compromise the overall structural integrity or reliability of the handle assembly.
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
Enables comfortable and quick removal of the pressure gauge for cleaning, maintaining the gun's ergonomic and aesthetic integrity while ensuring operation without the module, allowing for easy reassembly and potential replacement.
Implementation Method 1
a safety stop for the aforementioned removable portion of the handle, the stop being activated by the compressed air supplied to the handle through the relative inflow connector
Implementation Method 2
A mechanical locking obtained by means of forced coupling surfaces between the module and the handle, as well as possible magnetic locking between the module and the handle

AI summary
A manually-operated paint spray gun includes a body having a nozzle for atomizing paint to be sprayed and a handle forming a handgrip and provided with a connector for the inflow of compressed air to be supplied to the nozzle, wherein the handle of the gun has a compressed air regulator operatively associated to which is a pressure sensor at least part of which is arranged in a removable portion of the handle forming a substantial part of the dorsal area of the handgrip and is separated from the inflow connector.
