Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional dedicated keys are added to the terminal to provide extended control functions (such as double rate forward and backward), then the service control functions are enhanced, but the device complexity and hardware modification requirements increase
Solution Approach 1:
The patent introduces a message processing mechanism that acts as an intermediary between the terminal's existing keys and the service control functions. By analyzing sequences of control messages and identifying shortcut key patterns, the system enables extended functions without adding physical keys. The message processor interprets message sequences to trigger additional control operations, effectively using communication protocols as a mediator to expand functionality.
Solution Approach 2:
The patent transitions from a one-dimensional control approach (single key presses) to a multi-dimensional approach by utilizing the time and sequence dimensions of message transmission. By analyzing the order, timing, and combination of control messages, the system extracts additional control meanings from existing keys, effectively adding functional dimensions without hardware changes.
2Adaptability or versatility
If the terminal software is modified to provide extended control functions, then the service control capabilities are improved, but the ease of manufacture and deployment are worsened
Solution Approach 1:
The message processing mechanism serves as a software intermediary that can be deployed independently without modifying the terminal's core software. The server-side message processor analyzes control messages and generates additional control commands, effectively providing extended functionality through a middleware layer that bridges the terminal and service without requiring terminal software changes.
Solution Approach 2:
The system enables self-service by allowing the message processing and shortcut key analysis to occur automatically on the server side. The terminal simply sends standard control messages, and the server autonomously analyzes message sequences, identifies shortcut patterns, and executes extended control functions without requiring terminal software modifications or user configuration.
3Adaptability or versatility
If shortcut key analysis is performed on control message sequences, then extended control functions are enabled without hardware changes, but the processing complexity on the server side increases
Solution Approach 1:
The patent implements preliminary action by pre-defining shortcut key patterns and their corresponding control operations on the server side. The system prepares a mapping between message sequences and extended functions in advance, so that during operation, the server only needs to match incoming message sequences against these pre-defined patterns rather than performing complex real-time analysis, reducing processing complexity.
Solution Approach 2:
The system uses copying by creating virtual shortcut key representations from sequences of standard control messages. Instead of implementing complex analysis logic for each possible sequence, the system copies the structure and behavior of dedicated shortcut keys through message sequence interpretation, allowing extended functions to be replicated using existing key combinations without adding hardware complexity.
