Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the noise reduction headset uses fixed internal firmware and audio parameters, then the device structure is simple and manufacturing is easy, but the noise reduction range cannot be flexibly adjusted and adaptability is reduced
Solution Approach 1:
The patent applies universality by enabling the headset jack and plug to serve multiple functions: traditional audio transmission and data communication. By extending the existing jack and plug structures to include data communication capabilities, the system can both play audio and update firmware or adjust parameters without adding separate communication interfaces, thus improving adaptability while controlling complexity
Solution Approach 2:
The patent uses the terminal device as an intermediary to achieve flexible noise reduction adjustment. The terminal stores multiple noise reduction parameter sets and transmits them to the headset via the extended data communication channel. This intermediary approach allows the headset to access multiple parameter configurations without storing them internally, reducing headset complexity while improving adaptability
2Ease of operation
If the noise reduction headset has fixed audio parameters, then manufacturing precision requirements are reduced, but the practicality and usability are reduced
Solution Approach 1:
The patent applies preliminary action by pre-storing multiple noise reduction parameter sets in the terminal device before the user needs them. The terminal maintains a library of optimized parameters for different scenarios (music, voice calls, environmental noise), and when needed, the appropriate pre-configured parameters are transmitted to the headset. This eliminates the need for complex real-time parameter optimization in the headset while maintaining high practicality

AI summary
A noise reduction headset setting method, a terminal, and a noise reduction headset are provided. The method includes: triggering, when it is detected that a noise reduction headset is inserted into a preset headset jack and a communication setting instruction is received, the noise reduction headset to enter a communication mode, where the preset headset jack includes a first line used by a first channel and a sending channel, a second line used by a second channel and a receiving channel, and a third line used by a microphone and communication triggering (101); receiving a headset setting request in the communication mode, where the headset setting request is used to request a firmware upgrade and/or noise reduction parameter setting for the noise reduction headset (102); and setting the noise reduction headset according to the headset setting request by using the preset headset jack (103). By means of the method, a noise reduction range of a noise reduction headset is flexibly adjusted, and practicability of the noise reduction headset is improved.
