Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple wireless communication standards are supported on a single chip, then communication device versatility is improved, but device complexity and real estate consumption increase

Engineering Contradiction:
Improvemulti-standard capabilityVSAvoidcircuitry complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal frequency synthesizer architecture that can operate across multiple frequency bands and support multiple wireless communication standards (GSM, CDMA, WCDMA, LTE) using a single chip. The synthesizer uses programmable dividers and phase lock loops that can be configured through operational parameters to generate the required frequencies for different standards, eliminating the need for separate synthesizers for each standard and thereby reducing device complexity while maintaining multi-standard capability

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

Solution Approach 2:

The patent employs dynamic adjustment of operational parameters including frequency, bandwidth, and power levels to enable the same hardware components to adapt to different communication standards. By changing these parameters programmatically, the device can switch between standards without requiring separate dedicated circuits for each standard, thus reducing overall device complexity while maintaining versatility

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If multiple wireless communication standards are supported on a single chip, then communication device versatility is improved, but real estate consumption increases

Engineering Contradiction:
Improvemulti-band capabilityVSAvoidchip real estate
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent combines multiple frequency synthesizer functions into a single integrated circuit block that can generate frequencies for multiple bands (GSM 850/900/1800/1900, CDMA 800/1900, WCDMA, LTE). By merging what would traditionally require separate synthesizer circuits into one shared resource, the patent significantly reduces the chip real estate required while maintaining the ability to support multiple bands and standards through programmable configuration

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The frequency synthesizer is designed as a universal block that can serve multiple communication standards and frequency bands through programmable dividers and phase lock loops. This multi-functional approach allows a single chip area to support what would otherwise require multiple dedicated circuits, thereby reducing real estate consumption while maintaining multi-band capability

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

3Use of energy by moving object

If operational parameters are adjusted for different protocols and bands, then power consumption is optimized, but device complexity increases

Engineering Contradiction:
Improvepower consumptionVSAvoidparameter adjustment complexity
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The patent implements dynamic operational parameter adjustment where the frequency synthesizer and radio frequency components can be programmatically reconfigured for different protocols and frequency bands. This dynamic capability allows the system to optimize power consumption by activating only the necessary components for the current communication standard and band, while the programmable nature of the adjustment mechanism keeps the added complexity manageable through software control rather than hardwired switches

Inventive Principle:
Principle #15Dynamics

AI summary

Enhanced granularity operational parameters adjustment of components and modules in a multi-band, multi-standard communication device. For supporting two-way communications, a communication device includes receiver and transmitter modules. Each module includes various components that are configurable and/or programmable based on a protocol and band pair by which the communication device is operating. The communication device is a multi-protocol and multi-band capable communication device capable to operate in accordance with any one protocol and band at a first time and another protocol and band at a second time. The various components within each of the receiver and transmitter modules can be adjusted using one or more operational parameters. In some instances, a given component can be controlled by more than one operational parameter. Alternatively, certain components are controlled only one operational parameter. The operational parameters that configure the components may be calculated, retrieved from a memory, and/or determined using other means.
