Adjustable Cartridge Clasp for Stable Extrusion Applicator Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional applicators for extrusively dispensing work material lack adequate intermediate securement and support for containment vessels, leading to potential dislodgment and misalignment during use, especially when subjected to disruptive handling or in contexts with skeletal or open-frame receiving structures.
Innovation Solution
An applicator apparatus featuring a base portion with a handle and control member, a cage portion with a receiving compartment, and a clasp portion that is displaceably coupled to provide adaptively adjustable retention, forming a cuff around the containment vessel to maintain secure lateral support along the intermediate section.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional applicators use only frontal and rearward support measures for cartridges, then the structure remains simple, but adequate protection against dislodgment and misalignment during disruptive handling is not provided
Solution Approach 1:
The support structure is divided into multiple independent clasp portions (frontal, intermediate, and rearward) that can be positioned at different locations along the cartridge. Each clasp portion independently secures the cartridge at its respective location, providing distributed support that prevents dislodgment and misalignment during disruptive handling.
Solution Approach 2:
The clasp portions are designed to be adjustable and repositionable along the cartridge length. This dynamic capability allows the support structure to adapt to different cartridge sizes and configurations while maintaining reliable securement at optimal locations, resolving the contradiction between reliability and fixed structural complexity.
2Reliability
If stabilizing plates with grooves are used to hold cartridge rear edges, then cartridge swapping for different sizes is enabled, but intermediate securement and support along the cartridge length is insufficient
Solution Approach 1:
The clasp portions are designed with universal compatibility to work with various cartridge sizes and configurations. Each clasp can be positioned at different locations and adjusted to accommodate different cartridge diameters, providing intermediate securement across multiple applications without requiring application-specific components.
Solution Approach 2:
The retention mechanism extends from two-dimensional stabilizing plates to three-dimensional adjustable clasp portions that wrap around and secure the cartridge at intermediate locations. This adds a new dimension of retention by providing circumferential support at multiple points along the cartridge length, not just at the rear edge.
3Weight of moving object
If skeletal frame structures are used for lightweight applicators, then weight is reduced, but cartridge retention against dislodgment and misalignment is compromised
Solution Approach 1:
Rather than making the entire applicator structure heavy and rigid, the invention applies localized clasp portions at specific critical locations (frontal, intermediate, and rearward) where cartridge support is most needed. This provides reliable retention at key points while maintaining the overall lightweight skeletal frame structure.
Solution Approach 2:
The clasp portions are designed to nest within or attach to the skeletal frame structure, integrating the retention mechanism into the existing lightweight framework. This allows the skeletal structure to provide overall support while the nested clasp portions provide targeted cartridge securement without adding significant weight.

AI summary
An applicator apparatus is provided for extrusively dispensing work material from a containment vessel, A base portion includes a handle and a control member. A cage portion coupled to the base portion defines a receiving compartment for at least one containment vessel. The cage portion is provided with a proximate end disposed adjacent the base portion and an intermediate section extending longitudinally therefrom to a distal end. A drive portion coupled to the base portion is actuated responsive to the control member for driving extrusion of the work material from the containment vessel. A clasp portion displaceably coupled to the cage portion is displaceable relative to the cage portion between first and second positions, where the second position is disposed along the intermediate section of the cage portion. The clasp portion forms a cuff about the receiving compartment of the cage portion for laterally retaining the containment vessel received therein.
