Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a wireless charging apparatus uses electromagnetic induction method with coil combinations, then wireless charging capability is achieved, but the volume becomes large and it cannot charge multiple devices simultaneously

Engineering Contradiction:
Improvecharging capabilityVSAvoidapparatus volume
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The wireless charging apparatus is divided into multiple independent wireless charging units (first, second, third, and fourth units), each capable of charging one device. These segmented units are connected via folding units, allowing the system to charge multiple devices simultaneously while maintaining a compact form factor when folded.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The folding units enable the wireless charging units to be stacked and nested together when not in use, creating a compact configuration. The units can be folded up or down like an accordion, allowing the apparatus to transition between a compact stored state and an expanded charging state.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Adaptability or versatility

If wireless charging units are stacked in joining type with voids, then multiple devices can be charged simultaneously, but the structure becomes complex

Engineering Contradiction:
Improvemulti-device chargingVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The folding units provide dynamic flexibility to the structure, allowing the apparatus to transition between folded and unfolded states. This dynamic design enables the structure to adapt between compact storage and expanded multi-device charging configurations without requiring complex fixed mechanisms.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The folding units incorporate flexible voids that allow the wireless charging units to be stacked and connected through thin folding sections. This flexible design simplifies the overall structure compared to rigid multi-device charging stations, while still enabling simultaneous charging of multiple devices.

Inventive Principle:
Principle #30Flexible shells and thin films

3Object-affected harmful factors

If shielding films are added for electromagnetic field shielding, then electromagnetic interference is reduced, but manufacturing complexity increases

Engineering Contradiction:
Improveelectromagnetic interferenceVSAvoidmanufacturing simplicity
Core Design Contradiction:
Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The shielding films are integrated directly into the wireless charging units during the manufacturing process, merging the shielding function with the charging unit structure. This combination approach reduces the need for separate assembly steps and simplifies the overall manufacturing process while still providing effective electromagnetic field shielding.

Inventive Principle:
Principle #5Merging (Combining)
