Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If separate wireless charging module and heat-dissipating module are used, then heat dissipation function is provided, but device size increases

Engineering Contradiction:

Improveheat dissipationVSAvoiddevice size

Core Design Contradiction:

TemperatureVSVolume of moving object

Solution Approach 1:

The patent combines the wireless charging coil and heat dissipation components into a single integrated structure. The coil assembly includes both the charging coil and heat dissipation fins/structures that work simultaneously, eliminating the need for separate modules and reducing overall device volume.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The coil assembly serves multiple functions: it provides wireless charging through electromagnetic induction while simultaneously acting as a heat dissipation structure through its fins and conductive pathways. This multi-functionality allows one component to replace what would traditionally require separate dedicated components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If wireless charging coil is added to portable electronic device, then wireless charging function is provided, but device size should be increased to accommodate the coil and avoid heat affecting other components

Engineering Contradiction:

Improvewireless charging functionVSAvoiddevice size

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The wireless charging coil is integrated with heat dissipation structures (fins, conductive pathways) within the same assembly, allowing the coil to serve dual purposes of charging and thermal management without requiring additional separate components that would increase device volume.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The heat dissipation fins and thermal management structures are nested within or around the coil structure itself, utilizing the same spatial envelope. This nesting approach allows thermal management capabilities to be embedded within the charging function rather than adding external volume.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Temperature

If wireless charging coil and heat-dissipating module occupy separate spaces, then heat dissipation is effective, but space for accommodating both modules increases

Engineering Contradiction:

Improveheat dissipation effectivenessVSAvoidspace occupied

Core Design Contradiction:

TemperatureVSArea of stationary object

Solution Approach 1:

The heat dissipation fins and thermal pathways are integrated directly into the coil assembly structure, allowing heat dissipation functions to operate effectively within the same footprint as the charging coil rather than requiring adjacent separate modules.

Inventive Principle:

Principle #5Merging (Combining)
