Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire updated program is transmitted to configure the medical device, then the configuration is complete and reliable, but the transmission time increases and response speed decreases
Solution Approach 1:
The patent extracts only the changed parameters from the complete program update and transmits them separately as differential data. This allows the medical device to be configured with updated parameters faster while maintaining reliability through selective updating of only those parameters that have changed, rather than transmitting the entire program set.
Solution Approach 2:
The patent segments the program update process into identifying changed parameters and transmitting them as separate differential data elements. This segmentation enables faster transmission by breaking down the complete program into individual parameter changes, allowing the device to apply updates more quickly while ensuring each parameter is reliably configured.
2Manufacturing precision
If the entire updated program is transmitted to configure the medical device, then all parameters are updated, but the data transmission volume increases and power consumption increases
Solution Approach 1:
The patent extracts only the changed parameters from the complete program and transmits them as differential data. This reduces the volume of data transmitted, thereby reducing power consumption during the configuration process while maintaining accurate parameter configuration by focusing only on the parameters that require updating.
3Reliability
If the entire updated program is transmitted to configure the medical device, then the configuration is comprehensive, but the transmission time increases and therapy response is delayed
Solution Approach 1:
The patent extracts and transmits only the changed parameters as differential data, significantly reducing transmission time. This allows the medical device to receive and apply configuration updates faster, reducing therapy response time while maintaining configuration completeness by ensuring all necessary parameter changes are captured and applied.
Solution Approach 2:
The patent performs preliminary identification of changed parameters before transmission. By pre-processing the program update to identify which parameters have changed, the system can transmit only the necessary differential data, reducing transmission time and enabling faster therapy response while ensuring configuration completeness.
4Reliability
If the complete program data is transmitted, then data integrity is maintained, but the transmission bandwidth requirement increases and connectivity reliability is challenged
Solution Approach 1:
The patent extracts only the changed parameters and transmits them as differential data. This reduces the overall data transmission volume, lowering bandwidth requirements and reducing the complexity of the transmission process. Data integrity is maintained by ensuring that the differential data accurately represents the parameter changes and is properly applied to the complete program configuration.

AI summary
A system for providing stimulation to a patient, the system comprising one or more processors. The one or more processors are configured to receive an updated program indicating a plurality of stimulation parameters to configure a medical device to apply the stimulation to the patient and generate difference information based on one or more differences between an existing program and the updated program. The one or more processors are further configured to output the difference information to configure the medical device to apply stimulation to the patient with the plurality of stimulation parameters.
