Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation is used to control the projector for media playback, then the operation is straightforward and reliable, but the convenience and ease of operation deteriorates
Solution Approach 1:
The patent introduces a sound collecting device as an intermediary that captures voice instructions and converts them into control signals. This mediator bridges the gap between simple user input and complex system control, allowing users to operate the projector through natural speech without directly interacting with complex interfaces or controls
Solution Approach 2:
The patent replaces manual mechanical operation (buttons, remote controls, physical interactions) with an acoustic field-based control system. The sound collecting device captures acoustic signals (voice instructions) and converts them into electronic control codes, substituting the mechanical control system with an acoustic-to-electronic conversion system that improves ease of operation
2Ease of operation
If voice instructions are used to control the projector, then the ease of operation improves, but the reliability of accurate parameter detection may deteriorate due to incomplete commands
Solution Approach 1:
The patent implements a feedback mechanism where the processor analyzes the control code generated from voice instructions, determines whether necessary parameters are present, and if not, generates supplementary control codes or requests additional information. This feedback loop ensures that even if the initial voice command is incomplete, the system can still execute the correct operation by filling in missing parameters through feedback analysis
Solution Approach 2:
The patent prepares for potential incomplete commands by having the processor pre-analyze the control code structure and identify which parameters are necessary for each operation type. By beforehand determining the required parameters and having mechanisms to generate supplementary codes, the system cushions against the reliability issues that would arise from incomplete user commands
3Reliability
If the system generates supplementary control codes for incomplete parameters, then the reliability of media playback improves, but the device complexity increases
Solution Approach 1:
The patent performs preliminary analysis of the control code structure to identify which parameters are necessary for each type of media playback operation. By beforehand determining the required parameters and preparing supplementary code generation templates, the system ensures reliable execution without requiring complex real-time decision-making processes during actual playback control

AI summary
A projection system, a projection device and a control method thereof are provided. The control method of the projection device includes following steps: receiving a standard command; converting the standard command into an original control code through a definition module of the projection device; determining whether an original control code meets at least one necessary parameter through an allocation module of the projection device; in response to the original control code meeting at least one necessary parameter, the allocation module enabling one player of the at least one player to play one media file of the at least one media file according to the original control code; and in response to the original control code not meeting the at least one necessary parameter, the allocation module generating a supplementary control code, and the allocation module enabling one player of the at least one player to play the one media file of the at least one media file according to at least one of the original control code and the supplementary control code.
