Solution Overview
Problem
The existing electric light bulb type lighting apparatus is too large due to the size of its power source circuit components, particularly the transformer, which hinders its downsizing for practical use as a compact light source.
Innovation Solution
The apparatus incorporates an insulated power source circuit with a single transformer that generates a first DC power source voltage, allowing the light source drive circuit and speaker drive circuit to operate on different voltages, eliminating the need for multiple transformers and enabling the power source circuit to be downsized by mounting the power source, light source, and speaker drive circuits on multiple substrates within a compact casing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a conventional power source circuit with multiple transformers is used, then each circuit (light source drive, speaker drive, control) can operate independently with appropriate voltages, but the overall device size becomes too large for practical light bulb replacement
Solution Approach 1:
The patent merges multiple power source circuits into a single integrated power source circuit that includes one transformer and multiple voltage generation units. This consolidation reduces the overall device volume by eliminating redundant components while maintaining the ability to provide different voltages to light source, speaker, and control circuits through the multiple voltage generation units connected to the single transformer.
2Adaptability or versatility
If multiple transformers are provided for different voltage requirements, then each circuit can be optimized for its specific voltage needs, but the power source circuit size increases significantly
Solution Approach 1:
The single transformer in the power source circuit serves multiple functions by providing different voltages to different circuits through its multiple voltage generation units. The transformer is designed to generate first, second, and third voltages that can be supplied to light source, speaker, and control circuits respectively, making one component perform the work of what would traditionally require multiple transformers.
Solution Approach 2:
The power source circuit is segmented into multiple independent voltage generation units (first, second, and third voltage generation units) that can be selectively activated. This segmentation allows the system to provide different voltages as needed while using a single transformer, reducing overall volume while maintaining voltage adaptability for different circuit requirements.
3Volume of stationary object
If the power source circuit is downsized by using a single transformer, then the overall device volume is reduced, but it becomes challenging to provide sufficient power to multiple circuits with different voltage requirements
Solution Approach 1:
The patent adds a dimensional aspect to the single transformer by incorporating multiple voltage generation units that operate in parallel. This allows the system to deliver multiple different voltages simultaneously to different circuits, effectively increasing the power delivery capability in a multi-dimensional voltage space rather than being limited to a single voltage output.
