Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If current cable assemblies and mechanical support solutions are used, then basic data transfer functionality is provided, but mechanical failures occur due to internal and external forces causing signal loss and degradation

Engineering Contradiction:
Improvemechanical failure preventionVSAvoidsignal loss and degradation from mechanical forces
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies beforehand cushioning by incorporating strain relief features and protective structures into the cable assembly design before mechanical forces are applied. These features include flexible connectors, reinforced connection points, and shock-absorbing elements that are pre-installed to cushion against internal and external forces, preventing wire damage and mechanical failures before they occur.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The patent utilizes composite materials by combining different materials with complementary properties in the cable assembly. This includes using flexible materials for strain relief, rigid materials for structural support, and conductive materials for signal transmission. The composite structure provides both mechanical protection and electrical performance, resolving the contradiction between reliability and resistance to mechanical harmful factors.

Inventive Principle:
Principle #40Composite materials

2Stability of the object's composition

If rigid data transfer media and fixed mechanical support solutions are used, then stable connections are achieved, but interoperability, scalability, and upgradeability are limited

Engineering Contradiction:
Improveconnection stabilityVSAvoidinteroperability and upgradeability
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent applies dynamics by designing cable assemblies with flexible and adjustable components rather than fixed rigid structures. This includes flexible connectors that can adapt to different connection points, modular components that can be reconfigured, and mechanical support solutions that allow for adjustment and repositioning. This dynamic design maintains connection stability while enabling interoperability and future upgrades.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements universality by creating cable assemblies with standardized interfaces and multi-functional components that can work with various devices and connection types. The mechanical support solutions are designed to accommodate different cable types, connectors, and installation configurations, providing stable connections across diverse applications while enabling scalability and upgradeability without requiring device-specific custom solutions.

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

3Adaptability or versatility

If multiple different adaptors are used to support specific connection types, then connection compatibility is achieved, but device complexity and lack of cross-component support increase

Engineering Contradiction:
Improveconnection compatibilityVSAvoidnumber of different adaptors required
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies universality by designing a standardized cable assembly platform with universal connectors and mechanical support structures that can interface with multiple connection types. Instead of requiring separate adaptors for each connection type, the universal design allows a single cable assembly variant to support various connectors through standardized mounting interfaces, reducing the number of components needed while maintaining broad compatibility across different devices and connection standards.

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

AI summary

Method, apparatus, and electrical cable for high-speed connections. The apparatus can include an electrical cable, a wire sorter, an electrical mating paddle, and a cable assembly. The wire sorter can be coupled to an end of the electrical cable, and configured to receive wires extending from the end of the electrical cable and position the wires relative to one another in a predetermined arrangement to yield sorted wires. The electrical mating paddle card can then be coupled to the sorted wires according to the predetermined arrangement. The cable assembly can be configured to house the wire sorter and at least a portion of the wires. Moreover, the cable assembly can include a hot-melt injection chamber configured to at least partially immobilize the wires relative to the cable assembly when hot-melt is injected into the hot-melt injection chamber.
