Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple wireless communication chipsets and interfaces are used for concurrent communication with peripheral devices and mobile computing devices, then communication reliability and data integrity are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent segments communication into two distinct modes: central role for peripheral devices and peripheral role for mobile computing devices. This segmentation allows a single BLE chipset to handle different communication patterns sequentially, maintaining data integrity while reducing hardware complexity.
Solution Approach 2:
The controller dynamically switches between central and peripheral roles in the BLE communication stack. This dynamic role switching enables a single chipset to manage multiple communication scenarios, eliminating the need for multiple fixed chipsets while preserving communication reliability.
2Reliability
If multiple wireless communication chipsets are used for concurrent communication, then communication security and data integrity are improved, but power consumption increases
Solution Approach 1:
Communication is segmented into discrete connection events where the controller alternates between central and peripheral roles. This segmentation allows the single BLE chipset to enter low-power states between communication events, reducing overall power consumption while maintaining security through controlled connection management.
Solution Approach 2:
The system uses periodic connection events and advertising intervals in BLE communication. The controller periodically switches roles and establishes connections only when needed, allowing the chipset to remain in low-power mode during intervals, thus reducing power consumption while maintaining data integrity through scheduled secure connections.
3Reliability
If multiple wireless communication chipsets and interfaces are used for concurrent communication, then communication reliability is improved, but device size and manufacturing cost increase
Solution Approach 1:
The patent merges multiple communication functions into a single BLE chipset by implementing dynamic role switching between central and peripheral modes. This consolidation reduces device size and component count while maintaining communication reliability through software-managed connection protocols.
Solution Approach 2:
The single BLE chipset is designed to perform multiple functions by switching between central and peripheral roles. This multi-functionality allows the same hardware to communicate with both peripheral devices (as central) and mobile computing devices (as peripheral), eliminating the need for separate dedicated chipsets and reducing overall device volume.

AI summary
In one implementation, an insulin delivery system using an on-body network includes an insulin delivery device that is adapted to administer dosages of insulin to a patient; a controller that is adapted to control operation of the insulin delivery device, to establish a first network connection in which the controller acts in a central role, and to establish a second network connection in which the controller acts in a peripheral role; one or more peripheral devices that are adapted to generate patient data related to blood glucose levels and to transmit the patient data wirelessly over the first network connection, the peripheral devices acting in a peripheral role over the first network connection; and a mobile application installed on a mobile computing device that is programmed to communicate with the controller over the second network connection, the mobile application communicating in a central role over the second network connection.
