Nested Valve Assembly for Reliable Powder Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valve systems face challenges in efficiently controlling the flow of powdered or granular materials due to their design limitations, which can lead to operational difficulties depending on the characteristics of the materials or substances being handled.
Innovation Solution
The improved material supply assembly features a valve assembly with an outer and inner valve member, along with a base assembly that includes an engagement structure and locking mechanism, allowing for secure alignment and operation of the valve system to control material flow effectively, preventing relative movement and removal of the inner valve member from the base assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing valve systems are used to control material flow, then basic flow control is achieved, but operational reliability is insufficient due to design limitations
Solution Approach 1:
The valve member is divided into an inner valve member and an outer valve member that can rotate independently relative to each other. The inner valve member has discharge openings that can be selectively aligned or misaligned with the outer valve member's discharge section, allowing for more precise and reliable material flow control while maintaining a manageable structural complexity through modular segmentation.
Solution Approach 2:
The inner valve member is nested within the outer valve member, with the inner valve member rotatably disposed on the outer valve member. This nested configuration allows both valve members to work together in a compact arrangement, improving operational reliability through coordinated action while avoiding excessive device complexity by integrating multiple functions within a compact structure.
2Reliability
If the valve assembly is made secure with locking mechanisms, then prevention of accidental removal is achieved, but device complexity increases
Solution Approach 1:
The locking mechanism is designed to automatically engage and disengage based on the rotational position of the actuator relative to the outer valve member. The engagement structure includes locking members that self-lock when the actuator is in the correct position, eliminating the need for manual locking operations and reducing structural complexity while maintaining high security and reliability.
Solution Approach 2:
The locking mechanism replaces complex mechanical fastening systems with a simpler rotational engagement system. The actuator's rotation directly controls the engagement and disengagement of locking members through the engagement structure, substituting multi-step mechanical locking procedures with a single rotational action that is both reliable and structurally simple.

AI summary
A material supply assembly includes a valve assembly having an outer valve member and an inner valve member rotatable relative to the outer valve member. A base assembly includes an base structure and an actuator. An engagement structure is operative between the outer valve member and the actuator to prevent relative movement between the outer valve member and the actuator. A locking structure is operative between the inner valve member and the base structure to prevent relative movement between the inner valve member and the base structure. Movement of the actuator relative to the base structure moves the outer valve member relative to the inner valve member to operate the valve assembly.
