Movable Shutter Gate Positioning via Protruding Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing movable shutters for fluid conduits lack a reliable mechanism to ensure proper positioning of the gate, leading to potential fluid leaks and operational risks, and their installation and manufacturing processes are complex and costly.
Innovation Solution
A movable shutter design featuring a gate with protruding elements on its bearing surfaces or longitudinal surfaces, which prevents the locking mechanism from engaging unless the gate is correctly positioned, ensuring leakproof operation and simplifying the manufacturing and installation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional movable shutter design is used without positioning features, then the manufacturing and installation process is simpler, but the gate positioning reliability is poor leading to fluid leaks
Solution Approach 1:
The shutter design allows the gate to be dynamically positioned in two states: during operation, the gate can move between open and closed positions; during maintenance, the half-bodies can be separated. The relief elements provide dynamic engagement only when properly positioned, enabling reliable positioning without restricting operational movement.
Solution Approach 2:
The relief elements on the gate and bearing surfaces automatically engage when the gate is properly positioned, providing self-checking functionality. The system self-regulates to prevent improper positioning without requiring external monitoring or complex control mechanisms.
2Object-affected harmful factors
If relief elements are added to ensure proper gate positioning, then fluid leak prevention is improved, but the manufacturing complexity increases
Solution Approach 1:
Instead of making the entire gate or bearing surfaces complex, relief elements are added only at specific critical locations where positioning verification is needed. This localized approach prevents fluid leaks by ensuring proper engagement at key interfaces without requiring complex manufacturing throughout the entire structure.
Solution Approach 2:
The positioning verification function is segmented into discrete relief elements that can be independently manufactured and positioned. This segmentation allows for simpler manufacturing of individual components compared to creating a fully integrated complex positioning system.
3Ease of operation
If the locking mechanism is designed to engage only when gate is properly positioned, then operational safety is enhanced, but the device complexity increases
Solution Approach 1:
The locking mechanism incorporates relief elements that automatically verify gate positioning and prevent engagement if improperly positioned. This self-checking feature enhances operational safety without requiring external monitoring systems or complex control logic, as the mechanism itself performs the verification.
Solution Approach 2:
The relief elements act as intermediaries between the gate positioning system and the locking mechanism. They translate the physical position of the gate into a mechanical condition that either enables or prevents locking mechanism engagement, providing a simple yet effective safety verification.

AI summary
A movable shutter for a fluid conduit including two half-bodies consisting of a tube that forms a conduit, to the ends of which are affixed a flange and a plate having a bearing surface; a gate with a body defined by two longitudinal surfaces located opposite the bearing surfaces, which gate is mounted movably between the bearing surfaces, between a closed position and an open position; and a locking mechanism suitable for keeping the plates in a position in which they are either separated or close together, wherein at least one protruding element is provided on at least one of the bearing surfaces or on at least one of the longitudinal surfaces, such that if the gate is not properly positioned, the protruding element forms an obstacle that prevents the locking mechanism from keeping the plates in the position in which they are close together.
