Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional strobe devices are not compact due to the arrangement of the trigger coil and reflector, which results in inefficient light emission and illumination failures caused by imperfect lead wire connections.
Innovation Solution
A strobe device configuration with a conductive reflector acting as a trigger external electrode, a hollow core trigger coil, and a conductor connecting the secondary winding to the reflector, allowing the flash discharge tube to be inserted into the core and reducing the need for external lead wires, thereby achieving a compact and thin design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the trigger coil is disposed behind or under the reflector, then the lead wire connection reliability is improved, but the device size increases and compactness is reduced
Solution Approach 1:
The patent merges the reflector and trigger coil into a single integrated component structure. The trigger coil is disposed within the reflector body, eliminating the need for separate lead wire connections between distinct components. This integration maintains electrical connection reliability while significantly reducing the overall device volume and achieving a compact design.
Solution Approach 2:
The reflector is designed to serve multiple functions: it acts as both the light-reflecting component and the housing structure that contains the trigger coil. The trigger coil assembly is integrated into the reflector body, allowing the reflector to simultaneously provide optical function and structural support for the electrical component, thereby reducing the number of separate parts and overall device size.
2Reliability
If lead wires are used to connect the reflector and trigger coil, then the electrical connection is established, but power loss occurs due to lead wire resistance
Solution Approach 1:
The patent extracts and eliminates the lead wire from the system by directly integrating the trigger coil into the reflector body. The electrical connection is established through direct contact between the trigger coil terminals and the reflector's conductive parts, removing the intermediate lead wire component that causes resistive power loss.
Solution Approach 2:
The trigger coil and reflector are merged into a single integrated assembly where the electrical connection is made through direct contact within the integrated structure. This eliminates the need for separate lead wires and reduces the total resistance in the electrical path, thereby minimizing power loss.
3Reliability
If the trigger coil is disposed near the reflector with separate components, then the electrical connection can be made, but the device complexity increases
Solution Approach 1:
The patent combines the trigger coil and reflector into a single integrated component, reducing the number of separate parts that need to be assembled and connected. This integration simplifies the overall device structure, reduces assembly complexity, and eliminates the need for separate lead wire connections while maintaining reliable electrical contact.
