Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple batteries are stored at a charging station, then charging capacity is improved, but battery identification accuracy deteriorates
Solution Approach 1:
The patent divides the battery identification system into multiple segments: a first identifier stored in the battery device and a second identifier stored in the electronic device. By comparing these segmented identifiers, the system achieves accurate battery identification even when multiple batteries are present at the charging station, thus resolving the contradiction between charging capacity and identification accuracy.
Solution Approach 2:
The patent implements a feedback mechanism where the electronic device obtains the identifier from the battery device, compares it with the stored identifier, and provides feedback to determine whether the battery is correctly identified. This feedback loop ensures accurate battery identification while maintaining the ability to charge multiple batteries simultaneously.
2Reliability
If battery binding mechanism is implemented, then battery ownership protection is improved, but system complexity increases
Solution Approach 1:
The patent implements a self-service binding mechanism where the electronic device automatically obtains the battery identifier through near-field communication, compares it with the stored identifier, and determines battery ownership without manual intervention. This self-service approach enhances ownership protection while minimizing system complexity by avoiding complex manual binding procedures.
Solution Approach 2:
The patent replaces complex mechanical or manual battery binding mechanisms with an electronic identification system using near-field communication and identifier comparison. This substitution reduces physical complexity while maintaining reliable battery ownership protection through automated electronic verification.
3Productivity
If near-field communication is used for binding, then binding speed is improved, but communication range is limited
Solution Approach 1:
The patent applies preliminary action by storing the battery identifier in the electronic device before the actual binding process. When the battery is brought near the charging station, the binding can be quickly confirmed through near-field communication without requiring extensive search or verification, thus achieving fast binding within the limited communication range.
Solution Approach 2:
The patent uses near-field communication to rapidly skip through the binding process by directly comparing identifiers when devices are in close proximity. This rushing through the binding verification process achieves high binding speed while accepting the limited communication range constraint, as the quick verification doesn't require extended interaction distance.
