Solution Overview
Problem
The existing activation devices for electric battery units in torpedoes face challenges in ensuring safe storage and activation, particularly due to the risk of uncontrolled activation resulting from malfunctioning components, which can lead to excessive heating and potential battery fires.
Innovation Solution
The proposed solution involves a pneumatically actuated activation device with a series connection of operating supply reservoirs, where each reservoir is opened only after the preceding one in the series has been activated, ensuring controlled and sequential supply of operating materials to the battery cell section, thereby reducing the risk of uncontrolled activation. This is achieved through a cutting element that pneumatically opens a sealing element, connecting the operating supply connection to a pneumatic outlet, and utilizing a pressure reservoir with a sealing mechanism to manage the activation pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single operating supply reservoir is used for battery activation, then the activation process is simple and quick, but the risk of uncontrolled activation and excessive heating increases
Solution Approach 1:
The single operating supply reservoir is divided into multiple sequentially activated reservoirs (first operating supply reservoir, second operating supply reservoir, etc.). Each reservoir contains operating material and is activated in sequence through individual cutting elements and sealing elements, ensuring controlled feed of operating supplies to the battery cell section and preventing uncontrolled activation and excessive heating.
2Productivity
If multiple operating supply reservoirs are activated simultaneously, then the battery activation is fast and efficient, but the risk of uncontrolled activation and overheating increases
Solution Approach 1:
The activation devices are configured with pneumatic connections in series, where the first activation device must be activated before the second activation device can be activated. This preliminary sequencing ensures that operating supplies are fed to the battery cell section in a controlled sequence, maintaining both speed and control of the activation process.
3Ease of manufacture
If activation components are simplified for ease of manufacture, then production cost decreases, but the risk of malfunction leading to uncontrolled activation increases
Solution Approach 1:
The activation devices incorporate pneumatic connections that provide feedback control - the first activation device must complete its activation sequence before the second activation device receives pneumatic pressure. This feedback mechanism ensures that even if components are simple and prone to manufacturing variations, the sequential activation logic prevents malfunction-induced uncontrolled activation.
