Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If multiple batteries are stored at a charging station, then charging capacity is improved, but battery identification accuracy deteriorates

Engineering Contradiction:
Improvecharging capacityVSAvoidbattery identification accuracy
Core Design Contradiction:
Quantity of substanceVSMeasurement precision

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #23Feedback

2Reliability

If battery binding mechanism is implemented, then battery ownership protection is improved, but system complexity increases

Engineering Contradiction:
Improvebattery ownership protectionVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

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.

Inventive Principle:
Principle #25Self-service

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.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If near-field communication is used for binding, then binding speed is improved, but communication range is limited

Engineering Contradiction:
Improvebinding speedVSAvoidcommunication range
Core Design Contradiction:
ProductivityVSLength of stationary object

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.

Inventive Principle:
Principle #10Preliminary action

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.

Inventive Principle:
Principle #21Skipping (Rushing through)
