LCD Prompting System with Shrouded Chamber and Universal Mount
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional teleprompters are heavy, time-consuming to set up, and obstruct light, which affects image quality, while modern LCD technology offers opportunities for a lightweight, quick-to-deploy, and effective prompting system that minimizes light interference.
Innovation Solution
A compact LCD-based prompting system with a 45-degree inclined mirror and a universal mounting assembly for easy attachment to video cameras or camcorders, featuring a shrouded chamber to block unwanted light and a dual-thread mounting shaft for secure alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional teleprompters are used, then text prompting function is achieved, but the device becomes heavy and time-consuming to set up
Solution Approach 1:
The traditional integrated teleprompter system is segmented into separate components: a lightweight LCD display unit and a camera mounting system. This allows the prompter to be detached and reattached quickly without moving heavy equipment, reducing setup time while maintaining functionality.
Solution Approach 2:
The heavy mechanical CRT-based prompter system is replaced with a lightweight LCD electronic display. This substitution dramatically reduces weight while maintaining the text prompting function, allowing quick deployment without heavy mounting equipment.
2Ease of operation
If traditional prompters are mounted below the camera, then text is visible to the speaker, but the mounting process becomes complex and time-consuming
Solution Approach 1:
The mounting system uses a universal adapter that can attach to various camera types (tripod mounts, boom poles, handheld rigs) without requiring custom mounting procedures. This multi-functionality simplifies the mounting process across different equipment while reducing setup time.
Solution Approach 2:
The LCD display unit is pre-configured with mounting brackets and attachment mechanisms before deployment. This preliminary preparation allows for quick installation by simply attaching the pre-prepared unit to the camera, eliminating complex on-site assembly procedures.
3Reliability
If the camera lens is exposed, then the speaker can be recorded, but unwanted light interferes with image quality
Solution Approach 1:
The harmful element (unwanted light) is extracted from the optical path by introducing a light-blocking shield between the environment and the camera lens. This shield selectively blocks unwanted light while allowing the lens to remain exposed for recording, maintaining image quality without interference.
Solution Approach 2:
A light-blocking shield acts as an intermediary element between the external environment and the camera lens. This mediator selectively filters out unwanted light while permitting the lens to function normally, thereby protecting image quality without obstructing the recording capability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables a lightweight, quick setup and optimal image quality by blocking unwanted light and ensuring the camera's lens is positioned for best recording quality, while allowing the speaker to read text comfortably without visible obstruction.
Implementation Method 1
The see through mirror, which is approximately 40～60% reflective and 30～40% transparent, is securely held in position at a 45 degree angle to the screen surface of the LCD display
