Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional teleprompters are used, then the prompting function is achieved, but the device becomes heavy and time-consuming to set up
Solution Approach 1:
The traditional integrated teleprompter is segmented into separate components: a lightweight box housing the display and mirror, and a separate mounting assembly that attaches to the camera's accessory shoe. This allows the main body to remain lightweight while providing mounting capability when needed.
Solution Approach 2:
The mounting assembly is designed with universal compatibility to attach to various camera types through the standard accessory adapter shoe interface. The same mounting mechanism works with different camera models, eliminating the need for custom heavy mounting solutions for each device.
2Productivity
If traditional teleprompters are used, then the prompting function is achieved, but the setup process becomes complex and time-consuming
Solution Approach 1:
The system is divided into a simple box component and a separate mounting assembly, allowing each to be optimized independently. The box requires no complex alignment, and the mounting assembly uses standardized interfaces, reducing overall setup complexity.
Solution Approach 2:
The complex mechanical alignment and balancing systems of traditional teleprompters are replaced with a simple attachment to the camera's accessory shoe. This eliminates the need for sleds, counterweights, and precise mechanical alignment, reducing setup time and complexity.
3Volume of stationary object
If the camera lens is positioned close to the mirror, then the compactness is improved, but unwanted light enters the lens affecting image quality
Solution Approach 1:
The harmful element (unwanted light) is extracted from the system by creating a light-tight chamber that isolates the camera lens from external light sources. The chamber walls block stray light paths while maintaining the compact positioning of the lens near the mirror.
Solution Approach 2:
The chamber structure is designed to preemptively block unwanted light before it can reach the lens. The walls of the chamber act as preliminary barriers, preventing light interference before it affects image quality, rather than attempting to correct it afterward.
4Illumination intensity
If light sources are positioned above the apparatus, then the illumination is improved, but direct light shines on the display screen causing interference
Solution Approach 1:
The chamber structure, originally designed to block unwanted light, is utilized to also shield the display screen from direct overhead lighting. The same walls that protect the lens from stray light also protect the screen, converting a potential harmful effect into a beneficial shielding effect.
Solution Approach 2:
The interior surfaces of the chamber are designed with specific light-reflective or light-absorbing properties to optimize illumination of the display screen while preventing direct light paths from overhead sources. The local optical properties of the chamber walls are tailored to manage light quality in different areas.
