Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If batteries are used for energy storage, then energy density is improved, but power density deteriorates
Solution Approach 1:
The system divides the energy storage function into two separate components: batteries for energy storage and ultracapacitors for power delivery. This segmentation allows each component to optimize its specific function without compromise, with the battery providing high energy density and the ultracapacitor providing high power density.
Solution Approach 2:
The patent combines batteries and ultracapacitors into a hybrid energy storage system where both components work together. The battery and ultracapacitor are electrically connected through a power conversion device, creating a unified system that leverages the complementary strengths of both technologies.
2Quantity of substance
If batteries are used for energy storage, then energy storage capacity is improved, but charge/discharge rate deteriorates
Solution Approach 1:
The system separates the energy storage function (battery) from the rapid charge/discharge function (ultracapacitor). The ultracapacitor module handles high-rate charging and discharging operations, while the battery provides sustained energy storage capacity.
Solution Approach 2:
A power conversion device acts as an intermediary between the battery and ultracapacitor, managing power flow and coordinating charge/discharge operations. This intermediary enables the ultracapacitor to absorb or deliver rapid power changes while the battery provides stable energy storage.
3Power
If conventional capacitors are used, then power density is improved, but energy density deteriorates
Solution Approach 1:
The system merges conventional capacitors (ultracapacitors) with batteries in a hybrid configuration. The ultracapacitor provides high power density for burst applications, while the battery supplies high energy density for sustained operation, creating a complementary partnership.
Solution Approach 2:
The system dynamically switches between battery and ultracapacitor based on power demands. The control system monitors load requirements and automatically directs power flow to the appropriate source, optimizing performance for varying operational conditions.
4Power
If ultracapacitors are used for power delivery, then power density is improved, but energy storage capacity deteriorates
Solution Approach 1:
The system segments the power delivery function from the energy storage function. The ultracapacitor module is dedicated to providing high-power bursts, while the battery module handles sustained energy storage, eliminating the need for the ultracapacitor to compensate for limited energy capacity.
Solution Approach 2:
The hybrid system serves multiple functions: the battery provides long-term energy storage, the ultracapacitor delivers high-power bursts, and together they provide comprehensive energy management for diverse application requirements.
