Engineering Contradiction Analysis
1Area of stationary object
If passive heat dissipation is used by increasing the heat dissipation area of the charger, then heat dissipation area is improved, but heat dissipation efficiency remains insufficient
Solution Approach 1:
The patent divides the heat dissipation function into two parts: passive heat dissipation through the charger body surface and active heat dissipation through a dedicated heat dissipation channel. This segmentation allows each system to perform its specific function optimally, with the channel providing targeted high-efficiency heat removal while the body provides supplementary passive dissipation.
Solution Approach 2:
The patent introduces a heat dissipation channel as an intermediary structure that provides a dedicated pathway for heat and airflow between the charger interior and exterior. This intermediary element enables efficient heat transfer without requiring the entire charger body to be designed for maximum heat dissipation area.
2Reliability
If a heat dissipation device (fan, heat sink) is installed in the charging tray, then heat dissipation performance is improved, but the charging tray becomes too large and loses portability
Solution Approach 1:
The patent extracts the heat dissipation function from the charging tray body and relocates it to the connecting cable and charger plug. By taking out the heat dissipation components from the portable charging tray, the tray maintains its compact, portable design while still achieving effective heat dissipation through the separated cable-based system.
Solution Approach 2:
The patent moves the heat dissipation system from the two-dimensional surface of the charging tray to the one-dimensional linear path of the connecting cable. This dimensional change allows heat dissipation to occur along the cable length without increasing the charging tray's footprint or volume.
3Reliability
If air dispersal channel is located in the charging tray, then heat dissipation is enabled, but interference problems occur
Solution Approach 1:
The patent extracts the air dispersal channel from the charging tray and relocates it to the connecting cable. This extraction removes the source of potential interference from the charging tray environment while preserving the heat dissipation function through the cable-based airflow path.
Solution Approach 2:
The connecting cable serves as an intermediary medium that carries the heat dissipation airflow away from the charging tray. By using the cable as the mediator for heat and airflow transport, the system achieves heat dissipation without introducing interference elements into the charging tray space.
