Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electrical appliances often generate heat due to inefficient use of power received from outlets, leading to the need for cooling mechanisms to prevent damage, as they lack control over the power received from the grid.
Innovation Solution
A system and method that determine characteristics of an alternating current (AC) waveform to create voltage steps, allowing for optimized power delivery to loads by activating specific segments of a load at corresponding voltage levels, thereby reducing heat production and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If current electrical appliances regulate received current and voltage to provide proper power to components, then the desired power is delivered to electrical components, but heat is generated as an undesirable byproduct
Solution Approach 1:
The load is divided into multiple segments with different voltage ratings. The system identifies and activates only those segments compatible with the current AC voltage level, preventing power waste and heat generation in incompatible segments. This segmentation allows efficient power utilization across varying voltage conditions.
Solution Approach 2:
The system dynamically adjusts which load segments are active based on real-time AC waveform characteristics. By continuously monitoring voltage levels and adapting segment activation accordingly, the system optimizes power delivery and minimizes heat generation as voltage conditions change.
2Reliability
If fans and cooling mechanisms are added to prevent damage from heat, then electrical appliance damage is prevented, but device complexity increases
Solution Approach 1:
Instead of adding cooling mechanisms to handle waste heat, the invention converts the voltage mismatch problem into a beneficial segmentation strategy. By activating only compatible load segments, the system eliminates the harmful heat generation at its source, making cooling mechanisms unnecessary and maintaining system simplicity.
3Ease of operation
If the same voltage and current are provided to all electrical loads from the grid, then power distribution is simplified, but power utilization efficiency decreases
Solution Approach 1:
The system applies different activation strategies to different segments of the load based on their specific voltage ratings. Rather than treating the entire load uniformly, it identifies and activates only those segments matching the current voltage level, optimizing local power utilization while maintaining overall system simplicity.
