Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hybrid automobiles face inefficiencies in energy consumption due to underutilization of regenerative brakes and overutilization of energy dissipation brakes, as drivers are not adequately informed about optimal braking practices, leading to reduced energy efficiency.
Innovation Solution
A system that includes energy dissipation and regenerative braking sensors, a processor, and a display to analyze and provide braking information, such as energy efficiency rates and application percentages, to promote more efficient driving habits by displaying appropriate braking data and encouraging the use of regenerative brakes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If regenerative brakes are used to slow the hybrid automobile, then energy recapture efficiency is improved, but stopping capability is insufficient when extremely short stopping distance is required
Solution Approach 1:
The system merges regenerative braking and energy dissipation braking into a unified braking system that automatically selects or combines both methods based on driving conditions, achieving both energy recapture and sufficient stopping capability
2Reliability
If energy dissipation brakes are used to slow the hybrid automobile, then stopping capability is improved, but energy recapture efficiency deteriorates
Solution Approach 1:
The system uses feedback from braking information display to drivers about the type and amount of braking being applied, enabling drivers to adjust their braking behavior to maximize regenerative braking usage while maintaining adequate stopping capability
3Device complexity
If drivers are not provided with braking information, then device complexity is reduced, but energy efficiency deteriorates due to underutilization of regenerative brakes
Solution Approach 1:
The display system serves multiple functions: it informs drivers about braking type (regenerative vs. dissipation), provides feedback on energy recapture, guides driving behavior, and potentially integrates with other vehicle information systems, making the added complexity worthwhile through its multi-functional benefits
