Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wired charging method is used, then charging can be performed, but it is inconvenient and limited by the number of spare sockets
Solution Approach 1:
The patent replaces the mechanical wired charging system with a wireless electromagnetic induction charging system. The wireless charging terminal uses an electrified coil to generate a magnetic field, which induces current in the induction coil of the portable container, eliminating the need for physical cable connections and socket plugs.
Solution Approach 2:
The patent introduces electromagnetic fields as an intermediary medium for energy transmission. The electrified coil generates a magnetic field that serves as the mediator to transfer energy wirelessly to the induction coil, replacing the direct electrical connection through cables and sockets.
2Productivity
If wired charging is used, then charging function is provided, but manual connection is required which is cumbersome
Solution Approach 1:
The wireless charging system enables automatic charging when the portable container is placed on the charging terminal. The mounting base automatically detects the mobile device and establishes the charging connection without requiring manual intervention to plug or connect cables.
Solution Approach 2:
The patent eliminates the manual mechanical connection process by replacing it with automatic electromagnetic coupling. The system uses the positioning of the portable container on the mounting base to automatically establish the charging connection through electromagnetic induction, removing the need for manual cable handling.
3Ease of operation
If induction coil is used for wireless charging, then charging convenience is improved, but heat generation occurs during charging
Solution Approach 1:
The iron core serves as an intermediary that concentrates and guides the magnetic field from the electrified coil to the induction coil, improving charging efficiency and reducing energy loss that would otherwise be converted to heat. The iron core acts as a magnetic flux conductor to optimize the electromagnetic coupling.
Solution Approach 2:
The patent converts the generated heat into a manageable parameter by implementing heat dissipation structures. The heat sink and fan system transforms the harmful thermal effect into a controlled thermal management process, actively removing heat to maintain safe operating temperatures.
4Reliability
If mounting base with contact terminals is used, then closed loop is formed for charging, but complex connection structure is created
Solution Approach 1:
The mounting base integrates multiple functions into a single component: it provides mechanical support for the portable container, establishes electrical connections through contact terminals, and enables electromagnetic coupling for wireless charging. This multi-functionality reduces the need for separate connection mechanisms.
Solution Approach 2:
The patent merges the mechanical mounting function with the electrical connection function and the wireless charging function into an integrated system. The mounting base combines structural support, contact terminal connections, and induction coil positioning into a unified design that simplifies the overall connection structure.
