Pivoting Cartridge Support Sleeve for Stable Dispenser Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensers for 1K- or 2K-cartridges face challenges with easy handling and stability, particularly when flexible cartridges are used, due to conventional swivel mechanisms that complicate loading and unloading.
Innovation Solution
A dispenser design featuring a support sleeve that pivots about a perpendicular axis, allowing for easy loading and unloading of cartridges without moving the receiving space, with a pivot mechanism that includes a frame and a handle for activating the piston driving mechanism, and a lock mechanism to maintain stability during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a swivel mechanism is used to rotate the head plate or receiving structure from dispensing to loading position, then cartridge changing is simplified, but handling complexity increases and stability deteriorates
Solution Approach 1:
The invention divides the receiving structure into two independent parts: a stationary frame that remains stable during dispensing, and a movable support sleeve that pivots for loading/unloading. This segmentation allows the support sleeve to rotate independently without moving the entire receiving structure, simplifying the mechanism while maintaining stability during dispensing operations.
Solution Approach 2:
The support sleeve is designed with a pivot mechanism that allows it to dynamically change position between dispensing and loading orientations. This dynamic capability enables easy cartridge changing while the stationary frame maintains structural stability during actual dispensing operations.
2Ease of operation
If the complete receiving structure is rotated from dispensing to loading position, then cartridge loading is facilitated, but stability during dispensing deteriorates
Solution Approach 1:
The receiving structure is segmented into a stationary frame and a movable support sleeve. The frame remains fixed and stable during dispensing, while only the support sleeve pivots for loading operations. This prevents the entire receiving structure from rotating, maintaining stability during dispensing while enabling easy loading.
Solution Approach 2:
The pivoting function is extracted from the entire receiving structure and applied only to the support sleeve. This extraction allows the support sleeve to rotate independently for loading while the frame maintains its stable dispensing position, resolving the contradiction between loading ease and structural stability.
3Adaptability or versatility
If flexible cartridges are used, then adaptability is improved, but handling difficulty increases with conventional mechanisms
Solution Approach 1:
The movable support sleeve with pivot mechanism provides dynamic accessibility for flexible cartridges. The support sleeve can be rotated to a loading position where the cartridge outlet is accessible, allowing easy loading and unloading of flexible cartridges without complex manipulation, thereby improving ease of operation while maintaining adaptability.

AI summary
A dispenser for dispensing materials stored inside a cartridge includes a support sleeve, a receiving space to receive a cartridge in the support sleeve, a piston connected to a piston driving mechanism moveable through the receiving space to urge a material stored in the cartridge along a dispensing axis towards an outlet of the cartridge to dispense the material, a handle including a trigger to activate movement of the piston driving mechanism along the dispensing axis, the receiving space being formed by a frame, with the frame being configured to hold the support sleeve during dispensing, and the receiving space including a pivot mechanism to act between the frame and the support sleeve such that the support sleeve is capable of pivoting about a pivot axis aligned perpendicularly to the dispensing axis from a first position to a second position, and vice versa.
