Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a portable charger uses traditional direct charging connections, then charging reliability is improved, but adaptability to different power sources and devices deteriorates

Engineering Contradiction:

Improvecharging reliabilityVSAvoidadaptability to different power sources

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The portable charger is designed with dual charging capabilities: it can charge devices through both direct cable connections and wireless power transmission. The charger accepts power from multiple sources including wall outlets, car chargers, and wireless charging mats, making it universally compatible with various power sources and devices regardless of their charging interface type.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a portable charger supports multiple charging cables for different devices, then adaptability is improved, but device complexity and portability deteriorate

Engineering Contradiction:

Improvecompatibility with multiple devicesVSAvoidnumber of cables and accessories

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The invention combines multiple charging functions into a single portable charger unit. Instead of requiring separate cables and adapters for different devices, the charger integrates both wired and wireless charging capabilities in one device, eliminating the need for users to carry multiple charging accessories.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The portable charger replaces the mechanical cable connection system with a wireless power transmission system. By incorporating wireless charging capability, the charger eliminates the need for physical cables and connectors, reducing device complexity while maintaining compatibility with various electronic devices.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If a portable charger has large battery capacity to charge multiple devices, then productivity is improved, but weight and volume increase

Engineering Contradiction:

Improveability to charge multiple devicesVSAvoidcharger weight

Core Design Contradiction:

ProductivityVSWeight of moving object

Solution Approach 1:

The portable charger enables continuous charging operations by accepting power from external sources (wall outlets, car chargers, wireless charging mats) while simultaneously charging multiple devices. This continuous power input allows the charger to maintain its ability to charge multiple devices without requiring an excessively large internal battery capacity.

Inventive Principle:

Principle #20Continuity of useful action
