Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-channel ADC arrangements are designed with fixed performance per channel to meet the highest signal specifications, then reliability is improved, but hardware efficiency deteriorates
Solution Approach 1:
The patent implements dynamic configurability where ADC stages can be selectively enabled or disabled per channel through control logic. Each channel can be independently configured to use 1, 2, or 3 stages based on the signal requirements, allowing the system to adapt its performance and power consumption dynamically rather than operating at fixed maximum specifications for all channels.
Solution Approach 2:
The invention changes the operational parameters of individual ADC channels by allowing selective activation of stages. The control logic receives channel identification and configuration data, then adjusts the number of active stages per channel, effectively changing the resolution and power consumption parameters to match actual signal requirements rather than maintaining uniform maximum settings.
2Manufacturing precision
If multi-channel ADC arrangements are designed with fixed performance per channel, then manufacturing precision is improved, but adaptability deteriorates
Solution Approach 1:
The patent creates a universal ADC architecture where a single device can serve multiple application scenarios. By incorporating control logic that allows per-channel configuration of stage activation, the same hardware design can adapt to different signal requirements (high-resolution vs. low-resolution channels) without requiring custom designs, thus achieving multi-functionality while maintaining manufacturing uniformity.
Solution Approach 2:
The system transitions from static fixed-performance design to dynamic configurable design. The control logic enables real-time adjustment of channel configurations based on application requirements, allowing the same manufactured device to adapt to varying signal specifications across different applications and channels.
3Adaptability or versatility
If custom multi-channel ADC arrangements are tailored for specific applications, then adaptability is improved, but device complexity deteriorates
Solution Approach 1:
The patent merges multiple custom ADC designs into a single unified architecture. Instead of creating separate custom devices for different applications, the invention combines all possible stage configurations into one device with integrated control logic that can dynamically activate the appropriate number of stages per channel, thereby reducing the need for multiple specialized designs.
Solution Approach 2:
The control logic and configurable stage architecture enable a single universal device to replace multiple application-specific designs. The system can be programmed via control signals to achieve different performance levels on different channels, eliminating the need for separate custom-designed ADC devices for various applications.
4Productivity
If multi-channel ADC arrangements use parallel ADCs for each channel, then productivity is improved, but hardware efficiency deteriorates
Solution Approach 1:
The patent merges the functionality of multiple independent ADCs into a single shared architecture. Instead of having fully separate parallel ADCs that all operate at maximum capacity, the invention combines stage resources that can be dynamically allocated to different channels based on actual signal requirements, reducing redundant power consumption while maintaining concurrent processing capability.
Solution Approach 2:
The system implements dynamic resource allocation where ADC stages can be selectively activated or deactivated per channel. This allows concurrent processing of multiple channels while optimizing power consumption by only activating the necessary number of stages for each channel's signal requirements, rather than running all stages at full power continuously.
