Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If thermionic emission systems are used in triodes, then electron emission and signal amplification are achieved, but outgassing occurs causing vacuum degradation and reduced operational life
Solution Approach 1:
The patent extracts and removes contaminant atoms and molecules from the vacuum cavity through getter materials, separating the harmful outgassing products from the functional triode operation to maintain vacuum integrity
Solution Approach 2:
The patent converts the harmful outgassing process into a beneficial one by using getter materials that actively capture and immobilize the released contaminants, transforming the vacuum degradation problem into a controlled contamination management solution
2Adaptability or versatility
If wirebonded structures are used for grid, emitter and collector, then mechanical and electrical connections are enhanced with unique shapes, but manufacturing complexity increases
Solution Approach 1:
The patent applies wirebonding technology selectively to specific regions where enhanced mechanical and electrical connections are needed, creating unique shapes and structures only in those localized areas rather than throughout the entire device
Solution Approach 2:
The wirebonded structures are integrated within the existing triode cavity architecture, nesting the enhanced connection structures inside the vacuum envelope without disrupting the overall device layout
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
This approach improves the operational life and performance of triode devices by reducing contaminant atoms and molecules, maintaining a stable vacuum, and enabling efficient electron flow and amplification of electromagnetic signals.
Implementation Method 1
wirebonding technology forms mechanical and electrical connections to create unique shapes and enhance functionality
Implementation Method 2
Thermionic emitters use heat to expel electrons from a source, usually a metal. The heat is created by applying an electrical current to the emitter metal.
Implementation Method 3
The grid functions to control whether the emitted electrons can travel to the electron collector (anode). As voltage changes at the grid, more or fewer electrons are permitted to pass to the collector.
Implementation Method 4
The electron collector (anode) receives the electron current (emitted current/emitted electron flow). The collector current is the amplification of the input signal
Implementation Method 5
The triode allows for the amplification of low strength electromagnetic signals, e.g., radio signals, so that an analog or digital output can be created from received electromagnetic signals for additional uses
