G-Shaped Clamp Mounting for Independent Line Striper Spray Guns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing line striping machines require complex procedures to attach and detach spray gun assemblies from the mounting arm, often necessitating the removal of outer assemblies before installing or removing inner ones, which is inefficient and prone to mechanical issues due to corner catches.
Innovation Solution
A G-shaped clamp design that secures the mounting arm within its opening, allowing for independent installation and removal of spray gun assemblies without sliding on or off the end of the mounting arm, featuring a fastener that angles into the clamp's inner sides to secure the arm in place, and a window for measurement alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If spray gun assemblies are attached by sliding on and off the end of the mounting arm, then the attachment process is simple, but outer assemblies must be removed before installing or removing inner ones, reducing operational efficiency
Solution Approach 1:
The clamp is designed with a C-shaped configuration that allows it to be positioned around the mounting arm at different locations. The fastener extends through the C-shaped body and secures to the mounting arm, creating a nested arrangement where multiple clamps can be installed along the length of the mounting arm simultaneously, enabling independent attachment and detachment of inner and outer spray gun assemblies without interference
2Ease of manufacture
If spray gun assemblies are attached using a sliding mechanism, then installation is straightforward, but corner catches occur causing mechanical issues
Solution Approach 1:
The attachment mechanism is divided into two distinct functional components: the C-shaped body that provides the clamping structure and the fastener that provides the securing mechanism. The fastener extends through the C-shaped body at an angle and secures to the mounting arm through a separate hole, separating the clamping function from the fastening function to eliminate corner catches and improve reliability
3Adaptability or versatility
If multiple spray gun assemblies are mounted on the mounting arm, then coverage is improved, but attachment complexity increases due to interference between assemblies
Solution Approach 1:
The clamp acts as an intermediary device between the spray gun assembly and the mounting arm. The C-shaped body engages with the mounting arm, and the fastener secures the connection, providing a standardized interface that simplifies the attachment of multiple assemblies. This intermediary mechanism eliminates direct interference between assemblies by providing a uniform attachment point on the mounting arm

AI summary
A clamp for mounting on a mounting arm (16) of a line striping machine (2), the clamp comprising a body (24) that is G shaped, an opening through which the mounting arm is adapted to extend, and a fastener (32) configured to secure the mounting arm within the opening, wherein the opening is adapted to allow the clamp to be mounted on the mounting arm without sliding the claim along the mounting arm, and wherein the clamp is adapted to hang from the mounting arm without the fastener being engaged with the mounting arm; and a method of mounting a clamp on a mounting arm (16) of a line striper (2).
