Projector Time Control System for Presentation Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often forget to control time during presentations, leading to inefficiencies in projector usage, and existing solutions like bells can be distracting for audiences and organizers.
Innovation Solution
A time control system for projectors comprising an input module, processor, timer, and output module that allows users to set time parameters and generate reminder signals, such as visual and audio cues, to manage presentation time effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a bell is used to remind users to control time during presentation, then time management is improved, but it causes embarrassment and distraction to users, audiences, and organizers
Solution Approach 1:
The patent introduces a projector as an intermediary device to deliver time reminder information. Instead of using a bell that directly disturbs the presentation environment, the projector displays time information on the screen, serving as a mediator that conveys time management cues without causing auditory distraction or embarrassment to participants.
Solution Approach 2:
The patent extracts the time reminder function from the traditional bell alert system and integrates it into the projector's display capability. By taking out the auditory alert mechanism and replacing it with visual display, the system maintains time management functionality while eliminating the harmful auditory distraction.
2Productivity
If traditional time control methods are used, then time management is achieved, but users often forget to control time leading to presentation inefficiency
Solution Approach 1:
The patent implements a feedback mechanism where the projector continuously displays time information during the presentation. This visual feedback reminds users of the remaining time, ensuring they don't forget to control their presentation pace, thereby improving both time control reliability and presentation efficiency.
Solution Approach 2:
The system performs preliminary action by setting up the time control framework before the presentation begins. The projector is configured to display time information in advance, allowing users to be aware of time constraints before they become critical, enabling better time management from the outset.

AI summary
A time control system and a method for a projector. The time control system comprises an input module, a processor, a timer, and at least one output module. The input module is used to input at least one time parameter that is set by the processor into the timer. The timer is used to generate at least one trigger signal by counting the at least one time parameter. Meanwhile, the output module is used to output a reminder signal relating to the at least one trigger signal. The time control system is applied for reminding users.
