Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual adjustment is used to optimize tactile feedback, then feedback accuracy can be improved, but operation complexity and time consumption increase
Solution Approach 1:
The system automatically selects optimal frequency combinations and adjusts tactile feedback parameters without requiring manual intervention. The processor autonomously analyzes audio signals, determines corresponding frequency combinations from a preset library, and generates control signals for the tactile feedback device, enabling the system to serve itself and eliminate the need for manual optimization.
Solution Approach 2:
The patent replaces manual mechanical adjustment with an automated electronic control system. The processor uses algorithmic processing to analyze audio frequency spectra and automatically select corresponding tactile feedback parameters, substituting the mechanical process of manual adjustment with electronic signal processing and automated control.
2Reliability
If manual adjustment is used to optimize tactile feedback, then feedback quality can be improved, but time consumption increases
Solution Approach 1:
The system performs preliminary organization of frequency combination mappings before actual tactile feedback is needed. A preset library of frequency combinations corresponding to different audio frequency ranges is prepared in advance, allowing the processor to quickly retrieve and apply appropriate mappings during real-time operation without requiring time-consuming manual adjustment.
Solution Approach 2:
The patent replaces time-consuming manual adjustment processes with automated electronic signal processing. The processor rapidly analyzes audio signals and retrieves corresponding tactile feedback parameters from preset data structures, dramatically reducing the time required to optimize feedback quality compared to manual methods.
3Productivity
If automatic frequency combination selection is implemented, then operation efficiency is improved, but system complexity increases
Solution Approach 1:
The patent segments the audio frequency spectrum into distinct ranges and assigns corresponding preset frequency combinations for tactile feedback. By dividing the complex audio signal processing into manageable frequency bands with pre-defined mappings, the system achieves automated efficient processing while keeping the complexity of individual processing segments可控.
Solution Approach 2:
The patent introduces a preset frequency combination library as an intermediary between audio signal analysis and tactile feedback generation. This intermediate data structure stores pre-analyzed frequency mappings, allowing the processor to efficiently translate audio characteristics into tactile feedback parameters without requiring complex real-time calculations, thus improving productivity while managing system complexity.
