Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking mechanisms for valves on transport containers are difficult to use and may not be easily bypassed in emergencies, posing a challenge in securely accessing and releasing materials under varying conditions such as extreme temperatures and high pressures.
Innovation Solution
A pneumatic lock assembly that engages a lock pin with a contact surface on the valve stem, using a spring for secure closure and pneumatically disengaging with air pressure from a power source, allowing for manual override in emergencies, and featuring a cap assembly for protection and disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional locking mechanism is used on the valve, then the valve can be secured against unauthorized access, but the locking mechanism becomes difficult to use and cannot be easily bypassed in emergencies
Solution Approach 1:
The patent applies pneumatic principles by using compressed air to automatically actuate the lock pin through a bore in the cap assembly. This eliminates complex mechanical key-operated mechanisms while maintaining secure locking during normal operations and enabling rapid emergency release through pneumatic actuation
Solution Approach 2:
The lock assembly incorporates a spring-loaded pin that automatically engages with the valve stem groove to secure the valve in the closed position. The system serves itself by using the existing pneumatic infrastructure to trigger the release mechanism, eliminating the need for external key operations or complex manual bypass procedures
2Ease of operation
If the valve is made easily accessible for operation, then it can be quickly operated when needed, but it becomes vulnerable to unauthorized access and emergency bypass
Solution Approach 1:
The patent merges the valve operation mechanism with the lock assembly by integrating the lock pin directly into the valve stem structure. The lock pin engages with a groove on the valve stem, combining the sealing function and locking function into a single integrated component that maintains both accessibility and security
Solution Approach 2:
The lock pin acts as an intermediary element between the valve operating mechanism and the external environment. It physically blocks the valve stem from moving without proper authorization while allowing normal valve operation when engaged, serving as a mediator that reconciles accessibility with security requirements
3Speed
If a pneumatic lock system is implemented, then quick emergency disengagement is enabled, but the system complexity increases
Solution Approach 1:
The patent extracts the complex control logic from the locking mechanism and replaces it with a simple pneumatic actuation system. By removing the need for complex mechanical key-operated release mechanisms and using straightforward pneumatic pressure to drive the lock pin, the system achieves rapid disengagement while actually reducing overall mechanical complexity
Solution Approach 2:
The pneumatic bore in the cap assembly serves multiple functions: it acts as the activation mechanism for emergency release, provides a sealed pathway for pneumatic actuation, and integrates with the existing pneumatic infrastructure of the valve system. This multi-functionality reduces the need for separate components and simplifies the overall system
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The pneumatic lock assembly effectively secures the valve in a closed position while enabling quick disengagement with pneumatic power, ensuring safe and controlled material handling while allowing for emergency access.
Implementation Method 1
A spring biases a lock pin slidably received within the guide bore into engagement with a contact surface on the valve stem for securing the valve head in a closed position
Implementation Method 2
The lock pin may be pneumatically disengaged from the groove by forcing air from a pneumatic power source into a bore in the lock pin

AI summary
A pneumatic lock assembly for securing a valve comprises a lock pin engaging a contact surface on a poppet assembly. The head of a poppet creates a sealing relationship with an end of the valve. A guide with a bore extends between the exterior and interior of the valve terminating at a sleeve. The sleeve slidably receives a stem extending from the poppet head. A spring biases a pin, slidably received within the pylon bore, into engagement with a contact surface on the valve stem for securing the valve head in a closed position. The pin may be pneumatically disengaged from the groove by forcing air from a pneumatic power source into a bore in the pin. A cap assembly at the exterior of the valve provides protection for the lock assembly and allows for manual disengagement of the pin from the groove.
