Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If electronic components are used to optimize image transmission in the angle mirror, then image quality is improved, but the system becomes unreliable during power failures
Solution Approach 1:
The angle mirror system is divided into two independent image transmission paths: an electronic path (with cameras, sensors, and electronic processing) and an optical path (using fiber optic bundles). This segmentation allows the system to maintain image transmission capability through the passive optical path when electronic components fail, resolving the contradiction between image quality optimization and operational reliability.
2Reliability
If a second angle mirror is provided for backup sighting, then reliability during power failure is improved, but space requirements and system complexity increase
Solution Approach 1:
The backup sighting function is merged into the existing angle mirror housing by integrating a fiber optic bundle system within the same structure. The fiber optic bundle acts as a passive optical guide that transmits images from an external objective to a second viewing point, eliminating the need for a separate backup angle mirror and reducing overall system complexity while maintaining reliability.
Solution Approach 2:
A fiber optic bundle serves as an intermediary element that transmits optical images from the external objective to the backup viewing point without requiring electronic power. This passive optical mediator enables backup sighting functionality while avoiding the complexity of a complete second angle mirror system.
3Reliability
If fiber optic lines are used for image transmission, then reliability during power failure is improved, but image optimization capabilities are lost
Solution Approach 1:
The system segments image transmission into two distinct paths: an electronic path that provides image optimization capabilities (night vision, magnification, digital processing) and an optical path using fiber optic bundles that provides power-independent operation. Both paths share the same angle mirror housing and viewing points, allowing the system to select the appropriate path based on operational requirements.

Implementation Method 1
An objective (B) which is not arranged inside the housing (2) of the angle mirror (A) is provided. The objective (B) is connected to the angle mirror (A) via a connection (C), wherein the connection (C) is designed purely physically, in particular as a fiber optic line (30)
Implementation Method 2
The guiding of optical signals in the angle mirror is done by corresponding mirrors, which guide optical signals from the mirror head to the insight
Implementation Method 3
Prism arrangements are also known for guiding signals in an angle mirror

AI summary
The invention relates to an angle mirror including a backup sight. The angle mirror includes a housing connected to a mirror head and a lower part. An objective is arranged outside of the housing and is connected to the housing by an optical connection, for example a fiber optic line, that does not require electrical power or current to transmit the image from the objective. The mirror head and the objective provide separate images to a first insight and a second insight, respectively. The objective functions as a backup or auxiliary sight of the surrounding environment even in the event of a power failure.
