Bag-in-box Tapping Device with Above-Actuation Hygienic Valve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing devices for 'bag-in-box' packaging are limited in their ability to operate with different types of dispensing valves, failing to meet modern hygienic standards and requiring complex actuation mechanisms.
Innovation Solution
A dispensing device with an actuating mechanism that operates from above, featuring a valve receiving bearing with adjustable surfaces to accommodate various dispensing valve types, including Vitop and Rapak, and an exchangeable insert for easy conversion, along with a lever-based actuation system and a beverage outlet design that minimizes contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an actuating device with lever mechanism is used to operate dispensing valves, then the dispensing valve can be actuated, but it cannot meet modern hygienic requirements
Solution Approach 1:
The patent extracts the actuating mechanism from the traditional lever system and relocates it to actuate the dispensing valve from above through the insulating connector. This extraction eliminates the hygienic contamination risk associated with lever mechanisms that require close contact and complex moving parts, while maintaining the actuation function through a simplified vertical pressing motion.
Solution Approach 2:
The insulating connector serves as an intermediary element that transmits the actuating force from above to the dispensing valve piston while maintaining hygienic separation. The connector acts as a mediator that allows force transmission without requiring direct contact between the actuating mechanism and the valve components, thus meeting hygienic requirements.
2Adaptability or versatility
If a dispensing device is designed to accommodate different dispensing valve types, then versatility is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal actuating mechanism that can accommodate different dispensing valve types (Vitop and Rapak) through a single standardized interface. The actuating device designed according to the invention can operate both valve types by acting from above through the insulating connector, eliminating the need for multiple specialized actuating mechanisms and thereby achieving multi-functionality without proportionally increasing complexity.
3Adaptability or versatility
If the dispensing valve is actuated from below, then the valve piston can be moved vertically, but only Vitop dispenser valves can be operated
Solution Approach 1:
The patent inverts the traditional actuation direction from below to above. Instead of actuating the dispensing valve piston from below through complex lever mechanisms, the invention presses the piston from above through the insulating connector. This inversion simplifies the actuation method and enables compatibility with both Vitop and Rapak valve types that have accessible valve heads from above.
4Force
If a lever-based actuating mechanism is used, then mechanical advantage is achieved, but hygiene standards are compromised
Solution Approach 1:
The patent replaces the complex lever-based mechanical actuating system with a direct vertical pressing mechanism that acts through the insulating connector. This substitution maintains the necessary actuation force while eliminating the hygienic risks associated with lever mechanisms, as the simplified pressing action requires fewer contact points and less complex moving parts that could harbor contaminants.
