Quick Connect Cartridge Support for Power Dispensing Tool
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost of power dispensing guns makes it impractical for users to own multiple sizes to accommodate different cartridge sizes, as existing solutions do not efficiently support interchangeable cartridges without additional tools or complex procedures.
Innovation Solution
A power dispensing tool with a quick connect cartridge support assembly featuring a threaded connection and locking mechanism, allowing for easy attachment and secure interchanging of cartridges of various sizes using a cap, washer, and connector system, which includes a projection and inclined latch or spring assembly for locking, enabling rapid size changes without additional tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single power dispensing tool is used to accommodate different cartridge sizes, then cost-effectiveness and versatility improve, but the mechanism for interchangeable cartridges must be sufficiently secure and reliable
Solution Approach 1:
The cartridge support assembly is divided into separate components: a support body, a locking assembly with movable locking element, and a cartridge. This segmentation allows the locking mechanism to independently secure the cartridge while the support body provides structural attachment to the dispensing tool, enabling reliable connection without requiring multiple tool sizes.
Solution Approach 2:
The locking assembly includes a movable locking element that can transition between locked and unlocked positions. This dynamic mechanism allows the cartridge to be securely held during operation while enabling quick interchange when needed, simultaneously achieving reliability and adaptability.
2Ease of operation
If a quick connect mechanism is implemented for cartridge interchange, then ease of operation and time efficiency improve, but the mechanism complexity increases
Solution Approach 1:
The locking assembly is designed to be actuated by the user's natural motion during cartridge insertion or removal. The movable locking element automatically engages or disengages based on the cartridge's position, eliminating the need for separate locking actions or complex control mechanisms, thus maintaining simplicity while enabling quick interchange.
3Reliability
If a threaded connection with locking assembly is used, then reliability and security improve, but the number of parts and manufacturing complexity increase
Solution Approach 1:
The locking assembly is integrated with the cartridge support body as a single unit rather than separate components. This merging reduces the total number of parts, simplifies manufacturing, and eliminates the need for additional fasteners or assembly steps while maintaining the threaded connection's reliability through the unified structure.

AI summary
An apparatus for dispensing material is provided having a body portion and housing for supporting cartridges filled with materials for dispensing. The housing includes a dispensing end, an attachment end, and an elongated opening for receiving the cartridges. The apparatus further comprises an attachment assembly located at an end of the body portion for attaching the housing to the body portion. The attachment assembly includes a first set of threads located about the perimeter of the attachment assembly. A second set of threads are located about the perimeter of the attachment end of the housing for engaging the first set of threads, forming a threaded connection and attaching the housing to the body portion.
