Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless charging is used to charge the mobile device, then charging convenience is improved, but heat generation increases
Solution Approach 1:
The patent introduces an intermediary cooling system between the wireless charging unit and the mobile device. A mounting structure with cooling channels directs cooled air from the HVAC system through channels that contact the back surface of the mobile device, acting as a thermal mediator to remove heat generated during wireless charging.
Solution Approach 2:
The patent converts the harmful heat generated during wireless charging into a manageable thermal flow by directing cooled air through mounting structure channels. The heat is channeled and removed systematically through the mounting structure, transforming the harmful thermal effect into a controlled cooling process.
2Adaptability or versatility
If the mobile device is used for navigation applications, then navigation functionality is improved, but heat generation and battery drain increase
Solution Approach 1:
The patent implements preliminary cooling action by directing cooled air from the HVAC system through the mounting structure channels before the device overheats. The cooling air is prepared and positioned in advance through the mounting structure, ready to immediately cool the device when navigation applications generate heat.
3Reliability
If a cable is used to charge the mobile device, then charging reliability is improved, but ease of operation deteriorates due to tethering
Solution Approach 1:
The patent replaces the mechanical cable connection system with a wireless electromagnetic induction system. The wireless charging unit uses electromagnetic fields to transfer power to the mobile device without physical contact, eliminating the cable tethering while maintaining charging functionality.
4Ease of operation
If the mobile device is mounted in the vehicle, then ease of operation is improved, but heat accumulation increases
Solution Approach 1:
The patent uses pneumatic principles by utilizing the vehicle's HVAC system air flow to cool the mounted device. Cooled air is directed through the mounting structure channels, using pressurized air flow to actively remove heat from the device, transforming the mounting location from a heat trap to a cooling opportunity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively cools and charges mobile devices by directing forced air from the vehicle's HVAC system to the device, reducing heat buildup and maintaining battery health while providing convenient wireless charging.
Implementation Method 1
The system includes a supplemental passageway configured for providing forced air from the HVAC system to the mounting structure and a supplemental air outlet configured for providing the forced air to the mobile device when mounted on the mounting structure
Implementation Method 2
WO 2015/040841 A1 discloses a terminal installation structure for a vehicle with a heat radiating portion, wherein heat of the back surface of a terminal device is transmitted between the back surface of the terminal device and a terminal mounting surface

AI summary
A system for cooling a mobile device within a vehicle is provided. The system includes mounting structure within the vehicle cabin, which can be a portion of the center console. The HVAC system of the vehicle provides forced air to the mobile device when the mobile device is mounted to the mounting structure. The system may include a supplemental passageway in which forced air will be provided toward a supplemental air outlet disposed adjacent the mounting structure. The mounting structure may include a movable flap that is biased to a closed position that blocks the flow of air out of the supplemental air outlet, and that moves to open the supplemental air outlet in response to mounting the mobile device. The mounting structure may include nubs on a base surface to space the device away from the base surface and allow air to flow around the mobile device.
