Foldable Teleprompter with Angled Mirror and Tablet Mount
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional teleprompters are heavy, time-consuming to set up, and obstruct light, making them inefficient for modern video recording setups.
Innovation Solution
A foldable prompting apparatus with a 45-degree angled two-way mirror and a mounting assembly for easy coupling with video cameras or camcorders, using a tablet device to display text that is reflected to the user while blocking unwanted light and allowing only the speaker's image to be captured.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional teleprompters are used, then text display function is achieved, but the device becomes heavy and time-consuming to set up
Solution Approach 1:
The teleprompter is divided into separate components: a foldable housing that can be collapsed for transport, a detachable mounting assembly, and a tablet device that can be independently positioned. This segmentation allows the main housing to be lightweight and portable while still providing full functionality when assembled.
Solution Approach 2:
The housing incorporates foldable sides and a detachable mounting assembly that can be quickly attached and removed. The mounting assembly uses simple fasteners rather than complex permanent fixtures, enabling rapid setup and teardown without heavy tools or multiple people.
2Ease of operation
If traditional teleprompters are used, then text display function is achieved, but setup and alignment process becomes complex and time-consuming
Solution Approach 1:
The mounting assembly is separated from the main housing and designed as an independent component with its own detachable fasteners. This allows the mounting assembly to be pre-aligned and tested separately, then quickly attached to the housing and camera without complex field adjustments.
Solution Approach 2:
The mounting assembly incorporates self-aligning features and simple fasteners that allow a single operator to quickly attach and secure the prompter to the camera without requiring professional alignment equipment or multiple people to perform precise adjustments.
3Reliability
If camera lens is positioned behind the mirror, then image capture is enabled, but unwanted light enters the lens reducing image quality
Solution Approach 1:
A light shield is introduced as an intermediary component between the mirror assembly and the camera lens. This shield blocks unwanted light paths while allowing the optical image to pass through the mirror to the lens, effectively filtering out harmful light without interfering with the desired image capture function.
4Ease of operation
If tablet device is positioned to face the mirror, then text reflection is achieved, but light from above shines directly on the screen causing interference
Solution Approach 1:
The tablet device is rotated 90 degrees so that its display surface faces downward toward the mirror rather than upward toward the light source. This dimensional reorientation allows the text to be reflected into the viewer's field of view while the downward-facing screen avoids direct exposure to overhead lighting, eliminating glare without sacrificing text visibility.
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
The solution provides a lightweight, quick-to-set-up, and effective teleprompting system that minimizes light interference and maximizes image clarity, enabling efficient video recording with improved image quality.
Implementation Method 1
an inclined two-way see-through mirror which is placed in the inner space of the housing... The see-through mirror, which is approximately 40-60% reflective and 30-40% transparent, is held in position at a 45 degree angle to the screen surface of the tablet device. The optical image on the tablet device's display screen is reflected to the two-way see-through mirror and then reflected to the eyes of a speaker who looks into the mirror.

AI summary
The invention provides a prompting apparatus comprising a foldable prompting box which includes two symmetrical opposite walls which can be open and closed, a bottom board which can be folded up and released, and a rear wall, which jointly define a space for housing a two-way see-through mirror and the lens of the camera. The cover defines a space for a user to slide in a tablet device which runs a prompting software application. The pre-designed text is displayed on the tablet device's screen at a speed that the speaker feels comfortable to read. When the apparatus is not in use, the prompting box can be easily folded into a flat compact for the user's convenience to carry.
