Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional wiring and activation switches are used for each thermal battery, then individual battery activation is possible, but the system complexity, space, weight, and cost increase significantly
Solution Approach 1:
Multiple activation switches are merged into a single activation switch that can control multiple thermal batteries through a matrix configuration. The control unit integrates the switching functions, allowing one switch to selectively activate any individual battery or multiple batteries in combination, thereby reducing the total number of switches and wires required in the system.
Solution Approach 2:
The single activation switch is designed with multi-functional capability to control different combinations of thermal batteries. By working with the control unit, it can individually activate any battery or group of batteries, making the switch universal for all activation needs rather than requiring dedicated switches for each battery.
2Ease of operation
If multiple activation switches are installed for each thermal battery, then selective ignition is possible, but safety risks increase due to potential external noise and explosion issues
Solution Approach 1:
Multiple independent ignition control circuits are merged into a single integrated activation switch controlled by a control unit. This consolidation reduces the number of independent ignition circuits from N (where N is the number of thermal batteries) to 1, thereby minimizing the potential sources of external noise and reducing the overall safety risks associated with multiple ignition points.
Solution Approach 2:
The control unit acts as an intermediary between the single activation switch and the multiple thermal batteries. It processes the activation signal and selectively triggers only the intended battery or batteries, providing an additional layer of control that prevents accidental or unintended ignition and reduces safety risks.
3Ease of operation
If complex wiring and switches are used for thermal battery activation, then individual battery control is achieved, but manufacturing and installation costs increase
Solution Approach 1:
The system merges multiple wiring connections and switching components into a simplified configuration with fewer wires and a single activation switch. This reduction in component count directly lowers manufacturing costs by reducing the number of parts that need to be procured, assembled, and tested, as well as reducing installation complexity and associated labor costs.

Implementation Method 1
An ignition device is manufactured by using two types of explosives, i.e., a main agent and an initiator, and performs a function as the ignition device when the initiator explodes by an external electric signal (5 A/10 msec) and the main agent is combusted by the initiator.
Implementation Method 2
An activation time during which the solid electrolyte is melted by ignition of the heat source according to the ignition device flame
