Solution Overview

Problem

The USB cap on wireless USB Modems is prone to being lost during network connection as users need to pull it off, leading to potential loss and inconvenience.

Innovation Solution

An electronic device with a USB connector featuring an intermediate housing that moves relative to an outer housing, utilizing an elastic apparatus and a pendulum spring chute system to switch between received and released states, eliminating the need for a USB cap by allowing the USB connector to be pushed in and out through a through hole, ensuring secure retention and easy operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a USB cap is used to protect the USB connector, then the USB connector is protected from damage, but the USB cap may easily get lost when users need to pull it off for network connection

Engineering Contradiction:
ImproveUSB connector protectionVSAvoidUSB cap retention
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent merges the USB cap function with the housing structure by creating an integrated protective cover that is part of the housing itself rather than a separate removable component. The housing includes a protective cover that covers the USB connector opening, eliminating the need for a separate USB cap that can be lost.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent extracts the protective function from the removable USB cap and integrates it directly into the housing structure. The protective cover is built into the housing and remains attached, providing continuous protection without requiring a separate cap component.

Inventive Principle:
Principle #2Taking out (Extraction)

2Stability of the object's composition

If the USB connector is fixed on the housing, then the USB connector is stable and secure, but the user needs to remove the USB cap to connect, which complicates the operation

Engineering Contradiction:
ImproveUSB connector stabilityVSAvoidConnection operation
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The patent implements a sliding mechanism that allows the intermediate housing (containing the USB connector) to move dynamically between a received state (protected) and a released state (accessible). The elastic apparatus enables the housing to slide automatically, providing both stability when protected and ease of access when needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The elastic apparatus automatically returns the intermediate housing to the received state after the USB connector is accessed. The system self-regulates by using elastic force to maintain the protective position and automatically restore it after use, reducing manual intervention.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If the USB connector is exposed for easy access, then the connection operation is simple, but the USB connector is vulnerable to damage and contamination

Engineering Contradiction:
ImproveUSB connector accessibilityVSAvoidUSB connector protection
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The sliding mechanism dynamically adjusts the exposure of the USB connector based on operational needs. When the intermediate housing is in the received state, the USB connector is protected; when slid to the released state, it becomes accessible. This dynamic transition resolves the contradiction between protection and accessibility.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The intermediate housing acts as an intermediary between the USB connector and the external environment. It provides a protective barrier when in the received state and can be slid to expose the USB connector when needed, mediating between the need for protection and the need for accessibility.

Inventive Principle:
Principle #24Intermediary (Mediator)
