Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If modules are designed to be easily inserted and removed, then ease of operation is improved, but durability deteriorates

Engineering Contradiction:

Improveease of module insertion and removalVSAvoiddurability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The device is divided into separate functional modules that can be independently inserted and removed. Each module contains specific components (processor, display, battery, etc.) that can be reconfigured based on user needs, enabling easy customization while maintaining connection integrity through standardized interfaces.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The connecting member is designed with universal compatibility across different module types, featuring standardized electrical contacts and mechanical coupling elements that work with various module configurations. This allows the same connection mechanism to serve multiple functions: electrical connection, mechanical support, and alignment guidance.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If a frame or structure is used to house modules, then durability is improved, but adaptability deteriorates

Engineering Contradiction:

ImprovedurabilityVSAvoiddevice type and size variety

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The device configuration is made dynamic and reconfigurable rather than fixed. Modules can be added, removed, or rearranged to change device functionality and form factor. The connecting member enables this dynamic reconfiguration while maintaining structural integrity during use, allowing the device to adapt to different usage scenarios.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Multiple functional modules are nested together through hierarchical connection, with base modules providing core functionality and additional component modules extending capabilities. This nested architecture allows compact arrangement of components while maintaining accessibility for individual module replacement or reconfiguration.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Manufacturing precision

If precision alignment is required for module connection, then manufacturing precision is improved, but ease of operation deteriorates

Engineering Contradiction:

Improvealignment precisionVSAvoidease of module insertion and removal

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

The connecting member incorporates asymmetric alignment features such as guide pins, shaped interfaces, or directional engagement elements that provide tactile and visual guidance for proper module orientation. This asymmetric design naturally guides users into the correct alignment position, eliminating the need for high-precision manual alignment while ensuring repeatable connection geometry.

Inventive Principle:

Principle #4Asymmetry

Solution Approach 2:

The alignment and connection process is simplified by replacing complex mechanical adjustment mechanisms with self-aligning features. Magnetic attraction, spring-loaded contacts, or flexible connection elements automatically compensate for minor positioning variations, reducing the precision requirement for manual insertion while maintaining connection reliability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

The present technology discloses a frameless modular multi-functional electronic device. The electronic device includes a base module with a processor and multiple component modules, at least one of which is configured to connect directly in contact with the base module. The modules each include a connecting member to slidably align and mate the component modules together, and an electrical interface to transmit digital information and energy between connected base and component modules. The component modules are interchangeably connected directly in contact with each other and, when assembled, form the frameless modular multi-functional electronic device.
