Solution Approach 1:

The patent employs composite material structures including heat-conducting sheets with metal cores and plastic coatings, combined with phase change materials and gel substances. This composite approach enables effective heat conduction in ultrathin configurations by leveraging the high thermal conductivity of metal layers while maintaining the thin profile required for modern electronics.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent utilizes phase change materials that alter their physical parameters (phase transitions) in response to temperature changes. This allows the cooling system to dynamically adjust its heat absorption capacity based on thermal conditions, maintaining effective heat conduction even in scaled-down configurations.

Inventive Principle:

Solution Approach 1:

The patent introduces heat-conducting sheets and thermal interface materials as intermediaries between the sealed device interior and exterior surfaces. These intermediary components conduct heat through the sealed structure without compromising the seal, allowing thermal energy to escape while moisture remains blocked.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent employs capillary channels and porous structures that utilize capillary action to manage heat transfer. These micro-structural features enable thermal conduction pathways through the sealed housing without requiring physical openings that would compromise the seal integrity.

Solution Approach 1:

The patent integrates heat dissipation functionality directly into the shell components themselves. The heat-conducting sheets are combined with structural shell elements, merging the protective housing function with thermal management function into a single integrated component, thereby reducing overall device complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The shell components serve multiple functions simultaneously: structural protection, moisture sealing, and heat dissipation. This multi-functionality eliminates the need for separate dedicated heat dissipation components, reducing the overall complexity of the device architecture.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 1:

The middle shell body is constructed with composite materials featuring thermal management properties. The shell incorporates heat-conducting layers and phase change materials that enable it to actively participate in heat dissipation while simultaneously providing thermal insulation to protect users from scalds.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The middle shell utilizes phase change materials that undergo parameter changes (phase transitions) at specific temperature thresholds. This allows the shell to absorb excess heat when temperatures rise, actively contributing to heat dissipation while maintaining a safe external surface temperature for user contact.
