Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the battery pack is made compact for portability, then portability is improved, but charging capacity is reduced
Solution Approach 1:
The battery pack is designed to perform multiple functions: it can charge electronic devices wirelessly when placed on a charging board, and it can also function as a portable power source when detached. The battery pack includes both wireless charging circuitry and wired charging capabilities, allowing it to adapt to different charging scenarios and eliminate the need for separate charging solutions.
Solution Approach 2:
The battery pack incorporates dynamic switching mechanisms that automatically select between wireless and wired charging modes based on the detected charging scenario. The controller monitors connection status and power availability, dynamically adjusting the power supply route to optimize charging efficiency regardless of the charging method being used.
2Quantity of substance
If the connector is connected to an adaptor for charging, then charging capacity is improved, but movement freedom is reduced
Solution Approach 1:
The patent replaces the mechanical connection system (connector plugged into adaptor) with a wireless electromagnetic induction system. The battery pack includes a wireless charging circuit that can inductively receive power from a charging board without physical connection, thereby eliminating the constraint on movement freedom while maintaining charging capability.
Solution Approach 2:
The wireless charging board serves as an intermediary that enables power transfer without direct mechanical connection. The battery pack can be placed on the charging board to receive power wirelessly, or connected via connector when higher power transfer is needed, providing flexible charging options without restricting movement.
3Adaptability or versatility
If wireless charging circuit is added to the battery pack, then charging flexibility is improved, but device complexity is increased
Solution Approach 1:
The patent merges the wireless charging circuit and wired charging circuit into a single integrated battery pack design. The controller unifies the control logic for both charging methods, managing power flow from either source through a single power management architecture. This integration reduces the overall system complexity compared to having separate charging systems.
Solution Approach 2:
The battery pack is designed as a universal charging solution that incorporates both wireless and wired charging capabilities within a single device. The controller automatically detects the charging mode and switches between power supply routes, providing charging flexibility without requiring the user to manage multiple separate charging systems.
4Adaptability or versatility
If multiple switching routes are implemented for power supply, then power management flexibility is improved, but control complexity is increased
Solution Approach 1:
The controller implements dynamic switching between different power supply routes based on real-time detection of charging conditions. When wireless charging is detected, the controller activates the wireless power supply route; when wired charging is detected, it switches to the wired power supply route. This dynamic adaptation provides power management flexibility while using a unified control logic that manages complexity.
Solution Approach 2:
The controller continuously monitors the charging state and power source availability, using feedback signals to automatically select the appropriate power supply route. This feedback mechanism enables the system to adapt to changing conditions without requiring complex manual intervention, as the controller autonomously manages the switching between wireless and wired charging modes based on detected conditions.
