Flash Lamp Integrally Formed Electrodes for Uniform Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manufacturing a flash lamp with uniform light emission characteristics is challenging due to the difficulty in accurately fixing the electrode portions to the lead pins, affecting the consistency of the discharge and light emission.
Innovation Solution
The flash lamp design includes integrally formed anode and cathode portions on conductive linear members, which eliminates the need for separate fixation, allowing for precise positioning by simply fixing the linear members to the stein, with the anode and cathode having larger diameters and spherical shapes to ensure reliable discharge and uniform light emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the electrode portion is fixed to the tip end of the lead pin separately, then the flash lamp can be manufactured with modular components, but the fixing accuracy and positioning uniformity deteriorate
Solution Approach 1:
The electrode portion and lead pin are merged into a single integrally formed conductive linear member. This eliminates the separate fixation process and ensures precise positioning of the electrode portion relative to the lead pin, resolving the contradiction between modular assembly and fixing accuracy.
2Adaptability or versatility
If the electrode portion is fixed to the tip end of the lead pin separately, then the components can be manufactured independently, but the positioning uniformity and light emission consistency deteriorate
Solution Approach 1:
By combining the lead pin and electrode portion into one integrally formed member, the invention maintains manufacturing flexibility while ensuring uniform positioning of the electrode portion in all flash lamps, thus achieving consistent light emission characteristics.
3Volume of moving object
If the anode portion and cathode portion have small diameters, then the conductive linear members can be more compact, but the discharge reliability deteriorates
Solution Approach 1:
The conductive linear member has different diameters at different portions: the lead portion has a smaller diameter for compactness, while the anode and cathode portions have larger diameters to ensure reliable discharge. This local variation in dimensions resolves the contradiction between compactness and discharge reliability.
4Reliability
If the anode portion and cathode portion are formed with complex shapes, then the discharge characteristics can be optimized, but the manufacturing complexity increases
Solution Approach 1:
The anode and cathode portions are formed with spherical shapes, which are simple to manufacture yet provide excellent discharge characteristics. The spherical geometry ensures uniform electric field distribution and reliable discharge while minimizing manufacturing complexity.
