Injection Adapter Clipping Mechanism for Resin Spout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing injection valves for resin used in sealing electrical cable joints require multiple steps and movements for connection and disconnection, leading to increased assembly time and risk of resin spills, especially in limited spaces.
Innovation Solution
An injection adapter with a fluid conduit and clipping members that can be easily locked and unlocked in a single step, utilizing a locking and unlocking mechanism with protrusions and recesses on the spout, allowing for direct insertion and simple rotation-based disconnection, minimizing the need for screwing threads and reducing resin spillage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional injection valves with screwing threads are used to connect to the resin bag spout, then the connection is secure, but the connection and disconnection process requires multiple steps and manual rotation, increasing assembly time and difficulty
Solution Approach 1:
The connection mechanism is segmented into distinct functional elements: the inlet neck for insertion, multiple clipping members for securing, and protrusions/recesses for locking. This segmentation allows each component to perform its specific function efficiently, enabling secure connection through simple insertion and locking actions rather than complex screwing operations
Solution Approach 2:
The screwing thread mechanism is extracted and replaced with a clipping member system that uses elastic deformation and geometric interlocking. The clipping members are taken out from the main body and positioned to engage with recesses on the spout, providing secure connection without requiring rotational movement or threading operations
2Reliability
If multiple screwing rotations are required to fixate the spout to the injection valve, then the connection is secure, but the process becomes cumbersome in limited spaces and increases the risk of resin spills
Solution Approach 1:
The clipping members are designed to be self-actuating through elastic deformation. When the inlet neck is inserted into the spout, the clipping members automatically deflect and engage with the recesses, securing the connection without requiring manual manipulation. The protrusions on the spout automatically lock with the clipping members during insertion, providing secure fixation through the insertion motion itself
Solution Approach 2:
The connection mechanism utilizes changes in the elastic parameter of the clipping members. The clipping members are designed with specific elastic properties that allow them to deflect during insertion and then lock into place, providing secure connection through parameter change rather than mechanical threading
3Adaptability or versatility
If the injection valve design includes separate non-return valve and valve body parts, then the valve can be adjusted, but the requirement for in-site assembly increases installation time and complexity
Solution Approach 1:
The non-return valve and valve body are merged into a single integrated injection adapter assembly. The valve body forms part of the fluid conduit structure, and the non-return valve mechanism is incorporated within the same housing, eliminating the need for separate parts and in-site assembly while maintaining full functional capability
Solution Approach 2:
The injection adapter is designed as a universal component that combines multiple functions: fluid conduit, non-return valve, and connection mechanism with clipping members. This multi-functional design eliminates the need for separate specialized parts, reducing overall device complexity while maintaining adaptability and adjustment capability

Implementation Method 1
the free end of each clipping member is adapted to be deflected outwards in a radial direction when mechanical force is applied on said free end along a non-radial direction for unlocking the respective clipping member from the spout

AI summary
The present invention provides an injection adapter for a spout of a fluid container used in sealing and/or insulation of electrical cable joints. The injection adapter comprises: a fluid conduit having an inlet neck with an inlet opening that is adapted to be inserted into the spout; one or more clipping members arranged on an outer perimeter of the fluid conduit and oriented with free ends towards the inlet neck that are adapted to lock the spout, wherein the free end of each clipping member is adapted to be deflected outwards in a radial direction when mechanical force is applied in said free end along a non-radial direction for unlocking the respective clipping member from the spout. The invention also provides an injection valve with the injection adapter and a valve member for preventing back-flow of fluid.
