Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Computer systems, such as notebook computers, have fixed connectors and slots that limit flexibility in connecting peripheral devices, as users may prefer different connection options than those provided by the manufacturer, such as additional Secure Digital (SD) card slots.

Innovation Solution

An adapter that fits into existing slots, allowing multiple electronic devices with different electrical interfaces to be connected, including SD cards, by using bridge logic to convert the slot's interface type to match each device's interface, providing flexibility and compatibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple fixed slots are provided for different device types, then users have connection options, but the system lacks flexibility to accommodate user-preferred connection choices

Engineering Contradiction:

Improveconnection flexibilityVSAvoidnumber of slots

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adapter enables a single slot to perform multiple functions by accepting different device types (SD cards, USB devices, etc.) through a universal interface, eliminating the need for multiple dedicated slots while maintaining connection flexibility

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The adapter acts as an intermediary component between the fixed slot and various peripheral devices with different interfaces, translating between the slot's native interface and the device's interface to enable compatibility

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the manufacturer provides specific connection types, then the system has defined interface standards, but users cannot connect devices with different interface types

Engineering Contradiction:

Improveinterface compatibilityVSAvoiddevice connectivity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The adapter serves as a translation intermediary that converts signals between the slot's native interface protocol and the connected device's interface protocol, enabling seamless communication between incompatible interfaces

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The adapter dynamically changes interface parameters (such as signal voltage levels, data protocols, and connection topology) to match the requirements of the connected device, allowing the same slot to work with multiple device types

Inventive Principle:

Principle #35Parameter changes

AI summary

A system comprises a chassis and a slot that is externally accessible on the chassis. The slot is configured to receive a first electronic device having a first electrical interface type. The slot is also configured to receive an adapter comprising a second electrical device having a second electrical interface type that is different than the first electrical interface type.
