Solution Overview
Problem
Existing high-performance inductive charging devices for motor vehicles generate excessive heat during charging, which can damage both the charging device and the mobile terminal, and existing solutions to mitigate this issue, such as specific charging strategies or integrated cooling systems, either prolong charging time or increase space and cost requirements.
Innovation Solution
A compact charging device that couples with a vehicle's air-conditioning system to introduce cooling air, utilizing air inlet openings in the storage surface to cool both the charging unit and the mobile terminal, thereby avoiding the need for additional cooling systems and maintaining fast charging times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high-performance inductive charging is implemented, then charging speed is improved, but heat generation increases causing damage risk
Solution Approach 1:
The patent combines the inductive charging function with the vehicle's existing air-conditioning system by integrating a coupling unit that connects the charging device to the air-conditioning device. This allows the air-conditioning system to serve dual purposes: climate control and heat dissipation from the charging unit, thereby resolving the heat generation issue without requiring a separate cooling system
Solution Approach 2:
The patent introduces cooling air as an intermediary medium to transfer heat away from the charging unit. The coupling unit facilitates the flow of cooling air from the air-conditioning device through the charging device, enabling heat removal without direct thermal contact between the air-conditioning system and the charging unit
2Object-affected harmful factors
If cooling systems are integrated into the charging device, then heat management is improved, but device complexity and cost increase
Solution Approach 1:
The patent makes the vehicle's air-conditioning system multi-functional by enabling it to serve both climate control and charging cooling purposes. The coupling unit allows the air-conditioning system to provide cooling air to the charging device, eliminating the need for a dedicated cooling system and reducing overall device complexity
Solution Approach 2:
The charging device utilizes the vehicle's existing air-conditioning system to provide its own cooling needs. By coupling to the available cooling infrastructure, the charging device becomes self-sufficient for heat management without requiring additional independent cooling components
3Object-affected harmful factors
If cooling air is introduced via coupling unit, then heat removal is improved, but space requirements increase
Solution Approach 1:
The patent nests the coupling unit and air inlet openings within the existing structure of the charging device. The coupling unit is integrated into the charging device housing, and air inlet openings are incorporated into the storage surface, allowing cooling air introduction without adding external bulk or requiring separate cooling component housings
