Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a 3G UMTS transmission/reception device is placed near a telecommunications module, then the user can benefit from maximum communication availability without overloading the cellular network, but electromagnetic interference occurs between the two devices

Engineering Contradiction:

Improvecommunication availabilityVSAvoidelectromagnetic interference

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent integrates the transmission/reception device directly into the telecommunications module housing, combining two previously separate devices into one unified unit. This eliminates electromagnetic interference by removing the proximity issue while maintaining all functional benefits including communication availability and power sharing through the common housing and power supply connection.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated device serves multiple functions: it acts as both a telecommunications module for Internet connectivity and a 3G UMTS transmission/reception device for mobile phone communications. The single unified device can handle both Wi-Fi/DSL communications and cellular communications, eliminating the need for separate devices and their associated electromagnetic interference issues.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a separate transmission/reception device is added to the telecommunications setup, then 3G UMTS functionality is provided, but the number of cables and boxes increases making setup daunting for users

Engineering Contradiction:

Improve3G UMTS functionalityVSAvoiduser setup complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

By integrating the transmission/reception device into the existing telecommunications module housing, the patent reduces the number of separate boxes and cables from two devices to one unified device. This simplifies user setup while maintaining full 3G UMTS functionality, as the integrated unit requires fewer connections and occupies less space.

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If manufacturers produce multiple versions of telecommunications modules (with and without integrated transmission/reception device), then customer preferences are met, but economies of scale are limited and maintenance logistics are complicated

Engineering Contradiction:

Improvecustomer preference optionsVSAvoidmanufacturing efficiency

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent describes a single telecommunications module that universally provides both Internet connectivity and 3G UMTS transmission/reception capabilities through integration. This universal design eliminates the need for manufacturers to produce multiple versions of the device, thereby maintaining economies of scale while still meeting all customer needs through the integrated multi-functional unit.

Inventive Principle:

Principle #6Universality (Multi-functionality)
