Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a common design is used for information handling systems, then manufacturing standardization is improved, but mechanical alignment and retention of various form factors deteriorates

Engineering Contradiction:

Improvemanufacturing standardizationVSAvoidmechanical alignment and retention of various form factors

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The retention assembly is divided into separate functional components: a retention arm with a retention feature, a movable member that translates linearly, and a fastener mechanism. This segmentation allows each component to be optimized independently while maintaining overall standardization, enabling the system to accommodate various GPU form factors without compromising manufacturing standardization.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The retention arm is designed to be movable rather than fixed, allowing it to adjust dynamically to different GPU card positions and form factors. The linear movement capability enables the retention feature to engage with cards of varying lengths and configurations, resolving the contradiction between standardized manufacturing and adaptability to various form factors.

Inventive Principle:

Principle #15Dynamics

2Device complexity

If fixed retention structures are used, then structural simplicity is improved, but adaptability to different card form factors deteriorates

Engineering Contradiction:

Improvestructural simplicityVSAvoidalignment and retention of various form factors

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The retention structure incorporates a movable retention arm that can translate along a linear path, transforming a static structure into a dynamic one. This allows the simple fixed fastener mechanism to work with cards of various form factors by adjusting the retention arm position, maintaining structural simplicity while achieving adaptability.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The movable retention arm acts as an intermediary between the fixed fastener mechanism and the variable GPU cards. It mediates the interaction by adjusting its position to accommodate different card form factors, allowing the simple fixed structure to achieve complex adaptability functions.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If adjustable retention mechanisms are introduced, then adaptability to various form factors is improved, but device complexity deteriorates

Engineering Contradiction:

Improvealignment and retention of various form factorsVSAvoidretention assembly structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adjustable retention mechanism is segmented into independent functional components: the movable retention arm, the linear translation mechanism, and the fastener system. This segmentation allows for modular assembly and maintenance while providing the necessary adjustability for various GPU form factors, managing complexity through functional decomposition.

Inventive Principle:

Principle #1Segmentation

4Manufacturing precision

If mechanical coupling with linear movement is used, then precision alignment is improved, but manufacturing complexity deteriorates

Engineering Contradiction:

Improvemechanical alignment precisionVSAvoidassembly complexity

Core Design Contradiction:

Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The linear movement capability of the retention arm provides precise alignment through controlled dynamic adjustment rather than requiring complex precision manufacturing of fixed components. The movable design allows for tolerance compensation during assembly, improving alignment precision while reducing manufacturing complexity.

Inventive Principle:

Principle #15Dynamics
