Dispensing Gun Tool Stowage for Faster Viscous Material Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing guns for viscous materials lack an efficient onboard stowage system for accessory tools, requiring users to set the gun down and retrieve tools during application, which disrupts the process and reduces efficiency.
Innovation Solution
A dispensing gun with an onboard accessory tool stowage system that includes retention structures with receiving posts for securely holding finishing and scraping tools, allowing for easy access and secure retention during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If accessory tools are kept separate from the dispensing gun, then the gun structure remains simple, but tool accessibility is poor and application efficiency is reduced
Solution Approach 1:
The patent combines accessory tools (scrapers, spreaders, finishing tools) with the dispensing gun by providing retention structures on the gun body that securely hold these tools. This merging allows users to access tools directly from the gun without setting it down, improving ease of operation while adding only minimal structural complexity through the retention mechanisms.
2Productivity
If accessory tools are mounted on the dispensing gun, then tool accessibility is improved, but the gun structure becomes more complex
Solution Approach 1:
The retention structures integrate accessory tools with the dispensing gun body, enabling continuous access during application operations. This increases productivity by eliminating interruptions while the added complexity is limited to the retention mechanisms, which are designed to be structurally efficient.
Solution Approach 2:
The gun structure is segmented to include separate retention structures (clips, holders, or integrated mounts) that can independently secure different accessory tools. This segmentation allows the gun to maintain its primary dispensing function while adding tool-holding capabilities through modular additions, minimizing overall structural complexity.
3Loss of time
If multiple accessory tools are carried separately, then each tool can be optimized for its function, but time is lost retrieving tools during application
Solution Approach 1:
Accessory tools are pre-positioned on the dispensing gun via retention structures before the application process begins. This preliminary arrangement eliminates the need to retrieve tools during operation, reducing time loss. The stowage system adds minimal complexity by providing dedicated retention points for each tool type.
Solution Approach 2:
Multiple accessory tools are combined into a single integrated stowage system on the gun, allowing all tools to be accessed from one location without requiring separate retrieval actions. This merging reduces time loss while the stowage system maintains manageable complexity through unified design.

AI summary
A dispensing gun with an onboard tool stowage system is provided and has a frame body that includes a handle housing and a cartridge frame portion extending from said handle housing. The cartridge frame portion is configured for receiving a cartridge of work material therein. The frame body further includes at least one retention structure that has at least one receiving post protruding from said frame body. The dispensing gun further includes at least one accessory tool configured for detachable coupling with said at least one receiving post when stowed thereon, and a drive mechanism that is operably coupled to said frame body. The drive mechanism includes a drive member which passes displaceably into the cartridge frame portion responsive to operation of a trigger operatively disposed in the handle housing.
