Solution Overview
Problem
Existing hybrid vehicles with inductive charging options face challenges in efficiently and simply lowering the secondary coil for minimal distance during charging, leading to inefficiencies in energy transfer and maintenance requirements.
Innovation Solution
A hybrid vehicle design featuring a height-adjustable engine mount for the internal combustion engine, utilizing the motor bearing to lower the secondary coil relative to the chassis, allowing for energy-efficient positioning of the secondary coil close to the primary coil during charging, with hydraulic, pneumatic, or electromechanical adjustment mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the entire vehicle body is lowered relative to the chassis to minimize distance between primary and secondary coils, then inductive charging efficiency is improved, but the energy consumption and maintenance requirements increase significantly
Solution Approach 1:
The invention segments the lowering function by separating the secondary coil from the vehicle body and attaching it independently to the combustion engine. This allows only the combustion engine with the secondary coil to be lowered, rather than lowering the entire vehicle body, thereby reducing energy consumption while maintaining charging efficiency.
Solution Approach 2:
The invention introduces a height-adjustable engine mount as an intermediary mechanism between the combustion engine and the chassis. This mount enables selective lowering of the combustion engine with the attached secondary coil, achieving the desired positioning without requiring body-level adjustments.
2Loss of energy
If the entire vehicle body is lowered to achieve minimal distance between coils, then inductive charging efficiency is improved, but the complexity of the lowering mechanism and maintenance requirements increase
Solution Approach 1:
The invention simplifies the lowering mechanism by segmenting the system so that only the combustion engine with the secondary coil needs to be lowered. This reduces the complexity of the height-adjustable mechanism compared to lowering the entire vehicle body, as the engine mount mechanism is simpler and more localized.
3Use of energy by moving object
If only the combustion engine is lowered instead of the entire body, then energy consumption and maintenance needs are reduced, but the distance between primary and secondary coils may increase
Solution Approach 1:
The height-adjustable engine mount serves as an effective intermediary that enables sufficient lowering of the combustion engine with the secondary coil to achieve minimal distance from the primary coil, while consuming significantly less energy than body-level lowering. The mount provides the necessary adjustment range to optimize charging efficiency.
