Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The concentration of oxygen gas in electronic devices like hard disk drives decreases over time due to chemical reactions with internal components, leading to performance degradation and vibration issues, as the helium gas environment is not maintained effectively, causing a decrease in the desired mechanical vibration environment and insufficient oxidizer supply.
Innovation Solution
A method and system for actively generating a gaseous oxidizing agent component within the electronic device using a composition that can produce oxidizing agents like oxygen, ozone, or nitrous oxide, controlled by sensors and a power input to maintain a desired mole fraction in the interior gas space, ensuring optimal performance and reliability throughout the device's service life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hermetically sealed housing is used to maintain the interior gas space, then the initial gas composition is preserved, but the concentration of gaseous oxidizing agents decreases over time due to chemical reactions with internal components
Solution Approach 1:
The patent applies preliminary action by pre-installing a composition capable of generating gaseous oxidizing agents (such as peroxides or chlorates) inside the hermetically sealed housing. This composition remains dormant until activated by a generating device, which then produces the oxidizing agents in advance to compensate for future consumption through chemical reactions with internal components, thereby maintaining the desired concentration throughout the device's service life.
Solution Approach 2:
The system implements self-service through an automatic feedback mechanism where sensors continuously monitor the concentration of gaseous oxidizing agents in the interior gas space. When the concentration drops below a threshold, the control system automatically activates the generating device to replenish the oxidizing agents, eliminating the need for external intervention and maintaining reliable operation throughout the device's service life.
2Reliability
If oxygen concentration is maintained to prevent performance degradation, then component performance is preserved, but mechanical vibration environment deteriorates due to reduced helium mole fraction
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the composition of the interior gas space. Instead of maintaining a fixed helium-rich environment, the system actively controls the concentration of gaseous oxidizing agents (such as oxygen) to optimal levels for component performance. This allows the helium mole fraction to be reduced while compensating with sufficient oxidizing agents, thereby maintaining both component reliability and acceptable vibration characteristics throughout the device's operation.
Solution Approach 2:
The system transitions from a static gas composition to a dynamic one by continuously monitoring oxidizing agent concentrations and adjusting the generation rate accordingly. The control system modulates the activating device to maintain oxidizing agent levels within an optimal range, allowing the gas composition to adapt over time while balancing component performance requirements with vibration mitigation needs.
3Quantity of substance
If a composition that can generate gaseous oxidizing agents is added to the electronic device, then oxidizer supply is maintained, but device complexity increases due to additional components
Solution Approach 1:
The patent applies merging by integrating the oxidizing agent generation system into the existing electronic device structure. The composition capable of generating gaseous oxidizing agents is incorporated alongside standard device components, and the control system utilizes existing sensors and power management infrastructure. This consolidation minimizes the addition of discrete components while maintaining the necessary oxidizer supply for reliable operation.
Solution Approach 2:
The system implements multi-functionality by designing the generating device and control system to serve multiple purposes. The same controlling device that manages other electronic functions also regulates the generation of gaseous oxidizing agents. Sensors monitor both device performance parameters and oxidizing agent concentrations, allowing a single control system to manage both operational control and atmospheric composition maintenance, thereby reducing overall device complexity.
