Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If BLE MIDI controller uses wireless mode, then portability and ease of operation are improved, but MIDI message conflicts and data reliability deteriorate due to inability to enumerate multiple ports
Solution Approach 1:
The patent divides the single wireless MIDI connection into multiple virtual MIDI ports (e.g., BLE MIDI Port 1, BLE MIDI Port 2). Each virtual port operates independently to handle different MIDI message streams, preventing message conflicts while maintaining wireless connectivity. This segmentation allows simultaneous control of multiple devices without data interference.
Solution Approach 2:
The patent introduces a virtual MIDI port layer as an intermediary between the BLE MIDI controller and the host device. This virtual port layer manages message routing and prevents conflicts by directing different MIDI streams through separate virtual channels, thereby maintaining data reliability while preserving wireless operation benefits.
2Device complexity
If BLE MIDI controller uses single port in wireless mode, then device complexity is reduced, but functionality and adaptability deteriorate due to inability to perform and control simultaneously
Solution Approach 1:
The patent implements multi-functionality by enabling a single BLE MIDI controller to simultaneously utilize multiple virtual MIDI ports for different control functions. Each virtual port can be assigned to different instruments or software applications, allowing the controller to perform multiple functions simultaneously without requiring separate physical connections or increasing device complexity.
Solution Approach 2:
The patent transitions from a single-dimensional port structure to a multi-dimensional virtual port architecture. By adding the dimension of virtual port numbering (Port 1, Port 2, etc.), the system expands its capability to handle multiple simultaneous control streams without physically increasing the number of ports or complicating the device structure.
3Reliability
If multiple virtual MIDI ports are created, then MIDI message conflict and functionality are improved, but system complexity and setup time increase
Solution Approach 1:
The patent implements self-service by enabling the BLE MIDI controller to automatically detect available virtual MIDI ports and configure itself without requiring manual setup. The controller autonomously enumerates the virtual ports provided by the host device and establishes appropriate connections, thereby reducing setup time and simplifying user interaction while maintaining multiple port functionality.
Solution Approach 2:
The patent applies preliminary action by pre-configuring the virtual MIDI port structure on the host device before the BLE MIDI controller connects. The host device prepares the virtual port environment in advance, so when the controller connects, the ports are already available and ready for immediate use, eliminating the need for complex real-time configuration and reducing system complexity.
