Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control devices for hobs face increased power demands due to growing functionality and module counts, necessitating efficient power supply solutions while maintaining cost-effectiveness and space efficiency, without requiring extensive modifications.
Innovation Solution
A control device with multiple power interfaces that can connect to multiple hob power units, allowing for independent power distribution from different sources, including galvanically isolated interfaces, to manage varying power demands and prevent overloading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If control devices have increased functionality and more units/modules, then the power demand increases, but the manufacturing cost and space requirements increase
Solution Approach 1:
The control device is divided into multiple independently powerable modules or units, each capable of being powered separately through the power distribution network. This segmentation allows the control device to have increased functionality through multiple units while managing power demand in a distributed manner rather than requiring a single high-power supply.
2Adaptability or versatility
If control devices have increased functionality and more units/modules, then the power demand increases, but separate external power supplies increase manufacturing cost and complexity
Solution Approach 1:
Multiple power supply functions are merged into a single power distribution network that serves the entire control device. Instead of using separate external power supplies for different modules, the invention combines power distribution through a unified network that can deliver power to multiple units simultaneously, reducing overall system complexity and manufacturing costs.
Solution Approach 2:
The power distribution network is designed with universal interfaces and components that can serve multiple different units and modules within the control device. This multi-functional power network eliminates the need for specialized power supplies for each module, thereby reducing device complexity while supporting increased functionality.
3Power
If control devices use separate external power supply, then power demand is met, but assembly complexity and space requirements increase
Solution Approach 1:
The power distribution network integrates multiple power delivery paths into a single assembled unit, eliminating the need to separately assemble and connect multiple external power supplies. This merging of power supply functions into one integrated system significantly simplifies the manufacturing and assembly process while maintaining the capability to meet increased power demands.
