Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If air-cooled heat dissipation structure is used, then heat dissipation performance is ensured, but noise and energy consumption increase

Engineering Contradiction:
Improveheat dissipation performanceVSAvoidnoise and energy consumption
Core Design Contradiction:
TemperatureVSObject-generated harmful factors

Solution Approach 1:

The patent extracts the fan component from the heat dissipation system and replaces it with a passive heat dissipation structure. The cooling stand extends outward from the housing to provide a large surface area for natural convection heat dissipation, eliminating the need for active fan-based cooling and its associated noise and energy consumption.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent transitions from internal heat dissipation to external heat dissipation by extending the cooling stand outward from the housing. This dimensional extension creates additional surface area in three-dimensional space, enabling more effective passive heat dissipation without increasing internal device complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Temperature

If fan is added for heat dissipation, then heat dissipation capability improves, but device complexity and weight increase

Engineering Contradiction:
Improveheat dissipation capabilityVSAvoiddevice complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The patent removes the fan component entirely from the system and replaces it with a passive cooling structure. The cooling stand uses natural convection and radiation principles to dissipate heat without requiring any moving parts or active control mechanisms, thereby reducing device complexity.

Inventive Principle:
Principle #2Taking out (Extraction)

3Temperature

If cooling components are added, then heat dissipation improves, but device weight and thickness increase

Engineering Contradiction:
Improveheat dissipationVSAvoiddevice weight
Core Design Contradiction:
TemperatureVSWeight of moving object

Solution Approach 1:

The cooling stand serves dual functions: it provides structural support for the device and simultaneously acts as a heat dissipation component. By integrating these two functions into a single component, the patent avoids adding separate cooling hardware that would increase weight and thickness.

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

Solution Approach 2:

The cooling stand is designed as a thin, flexible structure that can be easily integrated into the device housing. This thin-film approach allows effective heat dissipation surface area to be added without significantly increasing device thickness or weight.

Inventive Principle:
Principle #30Flexible shells and thin films
