Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional power supply designs are used, then manufacturing cost is reduced, but the ability to output various power specifications is limited
Solution Approach 1:
The power supply is divided into a primary block containing the inverter circuit and multiple secondary blocks, each with transformers and rectifiers. This segmentation allows different secondary blocks to be configured for different power specifications while sharing the common primary block, enabling versatility without proportionally increasing manufacturing cost.
Solution Approach 2:
The primary block with the inverter circuit serves as a universal component that can supply power to multiple different secondary blocks. The inverter circuit can operate at different frequencies to accommodate various transformer designs, allowing one primary block to support multiple power specifications through different secondary block configurations.
2Adaptability or versatility
If multiple power specifications are supported, then versatility is improved, but device complexity increases
Solution Approach 1:
By separating the power supply into standardized primary and secondary blocks, the system achieves multiple power specifications without creating a complex monolithic structure. Each secondary block is a self-contained unit with specific transformer and rectifier configurations, making the overall system manageable despite supporting multiple specifications.
Solution Approach 2:
The inverter circuit frequency can be dynamically adjusted to match the requirements of different secondary blocks. This dynamic frequency control allows the same primary block to adapt to various power specifications by changing its operating frequency, reducing the need for multiple dedicated circuits for each specification.
