Solution Overview

Problem

Existing access devices for Internet and telephone connections are inflexible and require replacement when technology changes, leading to electronic waste and increased costs, as they are designed as closed-end devices with combined components that cannot be easily modified to support different connection technologies.

Innovation Solution

The access device features interchangeable USB sticks and adapter modules connected via standardized USB technology, allowing users to expand or change components as needed, enabling support for various connection technologies without requiring a new device, thus reducing hardware waste and costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If components are combined on one circuit board to increase rational production, then manufacturing efficiency is improved, but adaptability to different connection technologies deteriorates

Engineering Contradiction:
Improvemanufacturing efficiencyVSAvoidadaptability to different connection technologies
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent divides the access device into a permanent housing module and interchangeable functional modules (USB sticks, adapter modules). The circuit board is segmented to accommodate different USB sticks with different communication technologies (DSL, VDSL, fiber optic, mobile radio). This allows mass production of the housing module while enabling technology changes through simple module replacement rather than replacing the entire device.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The housing module is designed as a universal platform that can support multiple connection technologies through interchangeable USB sticks. The single housing module serves multiple functions by accepting different USB sticks for different technologies (fixed network, mobile radio network), eliminating the need for multiple specialized devices and enabling adaptability while maintaining manufacturing efficiency.

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

2Adaptability or versatility

If the entire terminal device is replaced when the modem cannot support required technology, then technology compatibility is improved, but cost increases and electronic waste is generated

Engineering Contradiction:
Improvetechnology compatibilityVSAvoidelectronic waste and costs
Core Design Contradiction:
Adaptability or versatilityVSLoss of substance

Solution Approach 1:

The patent extracts the modem functionality from the permanent housing module into separate, removable USB sticks. When technology changes are needed, only the USB stick is replaced rather than the entire terminal device. This extraction allows the housing module to be reused, reducing electronic waste and costs while maintaining technology compatibility.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent enables discarding only the obsolete USB stick while recovering and reusing the housing module. The housing module with its circuit board, power supply, and housing is recovered and continues to serve with a new USB stick that supports the required technology, thereby reducing electronic waste and avoiding the costs of replacing the entire device.

Inventive Principle:
Principle #34Discarding and recovering

3Ease of operation

If access devices are designed as closed-end devices, then ease of operation is improved, but flexibility to modify components deteriorates

Engineering Contradiction:
Improveease of setup and operationVSAvoidflexibility to modify components
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent introduces dynamic configurability to the access device by allowing users to interchange USB sticks and adapter modules based on their needs. The device transitions from a static, closed design to a dynamic system where components can be modified. The standardized USB interfaces maintain ease of operation while enabling flexibility through simple plug-and-play module replacement.

Inventive Principle:
Principle #15Dynamics
