Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If semiconductor chips are used in SSD apparatus, then data storage capacity and processing speed are improved, but heat generation increases leading to reliability degradation

Engineering Contradiction:
Improvedata storage capacity and processing speedVSAvoidreliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent introduces air tunnels that extend in the first direction (horizontal dimension) between the inner plate and upper wall, creating a three-dimensional heat dissipation pathway. This dimensional approach allows heat to be dissipated laterally through airflow rather than relying solely on vertical heat conduction, effectively managing heat from high-density semiconductor chips without compromising reliability

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

Solution Approach 2:

The patent employs forced convection through air tunnels and heat-dissipating fins to actively manage heat generation. By introducing airflow through the air tunnel structure and utilizing the fins to enhance convective heat transfer, the system effectively removes heat from semiconductor chips, preventing reliability degradation while maintaining high productivity

Inventive Principle:
Principle #29Pneumatics and hydraulics

2Temperature

If heat spreaders with high thermal conductivity are attached to components, then heat dissipation is improved, but device complexity and manufacturing difficulty increase

Engineering Contradiction:

Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The patent merges the heat dissipation function with the existing case structure by forming air tunnels between the inner plate and upper wall. This integration approach combines structural support and heat dissipation functions into a unified design, avoiding the need for separate heat spreaders and reducing overall device complexity while maintaining effective heat management

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The inner plate serves multiple functions: it provides structural support for the substrate and semiconductor chips, defines the air tunnel passage for heat dissipation, and acts as a mounting surface. This multi-functionality eliminates the need for dedicated heat spreader components, reducing device complexity while achieving effective heat management

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

Solution Approach 1:

The patent segments the case into distinct functional zones: the inner plate for component mounting, the air tunnel region for heat dissipation, and the upper wall for structural support. This segmentation allows each component to be manufactured and assembled independently with standard tolerances, reducing overall manufacturing precision requirements while maintaining effective heat transfer through the air tunnel structure

Inventive Principle:
Principle #1Segmentation
