Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric vehicles not designed for inductive pick-up arrangements face significant challenges in mounting and operating such systems due to space requirements and alteration difficulties, making it impractical to retrofit or install these systems.
Innovation Solution
A compact inductive pick-up arrangement featuring a prolongable actuator that adjusts the vertical distance between the pick-up and mounting portions, allowing for efficient positioning and energy transfer using magnetic induction, with a locking mechanism to secure the pick-up in optimal positions, and optionally utilizing multiple actuators and connecting portions for enhanced movement and weight distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a traditional pick-up arrangement with raising and lowering means is mounted on an electric vehicle, then the pick-up can be positioned close to the roadway for efficient energy transfer, but the space required in the vertical direction becomes excessively large
Solution Approach 1:
The pick-up is nested within a cavity of the vehicle's underside, allowing the pick-up to be stored compactly when not in use and deployed only when needed, thereby reducing the permanent vertical space requirement while maintaining positioning capability
Solution Approach 2:
The pick-up is made dynamically adjustable through a mechanical device that can lower it from the cavity or reposition it using a gear shaft and drive mechanism, allowing the system to adapt its configuration based on operational needs versus space constraints
2Adaptability or versatility
If an inductive pick-up arrangement is mounted on an existing electric vehicle not designed for such operation, then wireless energy transfer capability is added, but extensive alteration effort is required
Solution Approach 1:
The mounting device is designed to be universally applicable to existing electric vehicles by utilizing the vehicle's existing cavity structure and mounting points, allowing the same pick-up arrangement to be installed on different vehicle models without custom fabrication for each vehicle
Solution Approach 2:
The pick-up arrangement is segmented into modular components (pick-up, mounting device, actuator, control unit) that can be independently installed and adjusted, reducing the complexity of integration with existing vehicle systems and minimizing alteration effort
3Productivity
If the pick-up is positioned close to the roadway for efficient energy transfer, then magnetic induction efficiency is improved, but the risk of damage from road irregularities increases
Solution Approach 1:
The pick-up is equipped with adjustable positioning mechanisms that allow dynamic adjustment of its position relative to the roadway, enabling the system to optimize the gap for efficient energy transfer while maintaining the capability to raise or reposition the pick-up to avoid damage from road irregularities
Solution Approach 2:
The control unit monitors the position and operational status of the pick-up, and can automatically adjust its position or activate protective measures when road irregularities are detected, thereby maintaining both efficiency and durability through real-time feedback control
