Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a static retention system is used for peripheral cards, then the structure is simple and easy to manufacture, but it cannot accommodate diverse configurations and dimensions of peripheral cards

Engineering Contradiction:

Improveaccommodation of diverse peripheral card configurationsVSAvoidretention system structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The retention system incorporates switchable inserts with multiple notches that can be repositioned along the chassis end, transforming a static structure into a dynamic one. This allows the same retention system to accommodate peripheral cards of various lengths and configurations by switching between different notch positions, thereby improving adaptability without requiring multiple dedicated retention structures.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The retention system is designed with multiple notches on each insert, enabling a single retention mechanism to serve multiple functions by accommodating different peripheral card types and configurations. The switchable nature of the inserts allows one retention system to replace what would traditionally require multiple specialized retention structures.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Temperature

If a static retention system is used for peripheral cards, then the device complexity is low, but the cooling efficiency is suboptimal

Engineering Contradiction:

Improvecooling efficiency of peripheral cardsVSAvoidretention system structure

Core Design Contradiction:

TemperatureVSDevice complexity

Solution Approach 1:

The switchable inserts with multiple notches create dynamic airflow paths that can be optimized for different peripheral card configurations. By adjusting the insert positions, the system adapts airflow patterns to match the specific heat dissipation needs of different card types, improving cooling efficiency while maintaining a relatively simple overall structure.

Inventive Principle:

Principle #15Dynamics
