1Temperature

If traditional airflow-based cooling is used, then cooling capability is provided, but temperature control precision deteriorates and heating capability is lost

Engineering Contradiction:
Improvetemperature control precisionVSAvoidheating and cooling versatility
Core Design Contradiction:
TemperatureVSAdaptability or versatility

Solution Approach 1:

The patent applies multi-functionality by integrating both heating and cooling capabilities into a single information handling system. The system includes a thermoelectric cooler that can operate in reverse to function as a heater, allowing the same device to provide both heating and cooling functions depending on operational requirements, thus eliminating the need for separate heating and cooling systems.

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

Solution Approach 2:

The patent implements dynamic temperature control by using adjustable-speed fans and controllable thermoelectric cooler elements. The fan speeds can be varied to adjust airflow intensity, and the thermoelectric cooler can be dynamically activated or deactivated based on real-time temperature conditions, enabling precise and adaptive temperature management rather than fixed-state cooling.

Inventive Principle:
Principle #15Dynamics

2Temperature

If thermoelectric cooler is added for precise temperature control, then temperature control precision is improved, but device complexity increases

Engineering Contradiction:
Improvetemperature control precisionVSAvoidsystem structural complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The patent merges the heating and cooling functions into a single integrated thermal management system. The thermoelectric cooler is combined with existing fans and heat sinks, and the control logic for temperature regulation is integrated into the system's existing management architecture, reducing the need for separate control systems and minimizing overall structural complexity despite adding thermoelectric functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system implements self-service temperature regulation by using temperature sensors that continuously monitor component temperatures and automatically activate the thermoelectric cooler or adjust fan speeds as needed. The system autonomously manages its own thermal conditions without requiring external intervention or complex manual control mechanisms.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If multiple heat-rejecting media are used, then temperature control versatility is improved, but device complexity increases

Engineering Contradiction:
Improvetemperature control versatilityVSAvoidthermal management structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the thermal management system into distinct functional zones with different heat-rejecting media. First heat-rejecting media are positioned to handle heat from specific components (such as CPU), while second heat-rejecting media address heat from other components (such as GPU). This segmentation allows each media type to be optimized for its specific thermal load while maintaining overall system versatility through selective activation.

Inventive Principle:
Principle #1Segmentation
