Solution Overview
Problem
Conventional methods for multidirectional observation of objects in industrial settings require complex and costly setups, often resulting in reduced efficiency and accuracy due to differences in working distances and the need for frequent adjustments, leading to fatigue and decreased observation quality.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple reading devices are disposed at fixed positions to observe different faces simultaneously, then observation time is reduced and productivity is improved, but device complexity and cost increase
Solution Approach 1:
The patent combines multiple reading functions into a single reading device by using mirrors to redirect light paths from different faces of the object to a common imaging position. This merging approach maintains simultaneous multi-directional observation capability while reducing the number of reading devices from multiple to one, thereby reducing device complexity and cost while preserving productivity improvements
Solution Approach 2:
The patent introduces mirrors as intermediary elements that mediate between the object faces and the single reading device. The mirrors redirect light paths from different faces to the common imaging position, enabling the single reading device to capture images of multiple faces simultaneously without requiring multiple reading devices, thus resolving the contradiction between productivity and device complexity
2Measurement precision
If the working distance is adjusted for each face to achieve in-focus imaging, then measurement precision is improved, but operation complexity and time increase due to frequent adjustments
Solution Approach 1:
The patent creates equipotential working conditions by using mirrors to ensure that all faces of the object are imaged at the same working distance from the single reading device. This eliminates the need for frequent adjustments when moving between faces, as the optical path length is equalized for all observation directions, thereby maintaining measurement precision while dramatically improving ease of operation
Solution Approach 2:
The patent changes the optical path configuration by introducing mirrors that redirect light paths, thereby transforming the working distance parameter from face-dependent to uniform across all faces. This parameter change ensures that the reading device operates at a constant working distance regardless of which face is being observed, eliminating frequent adjustments while maintaining imaging focus accuracy

AI summary
A multidirectional simultaneous observation optical system is composed of, as shown in FIG. 2, side image acquiring prism systems (145A, 145B) and so forth for acquiring side images of an object (11) and bottom image acquiring prism system (185F) for acquiring a bottom image. The prism system (145A) and so forth include optical path direction changing prisms (14A, 14B, 18F) and so forth respectively. An open space for acquiring the top image is defined directly above the object (11). The optical paths of the light beams emerging from the prism system (145A) and so forth extend upward from the object (11), and are so disposed as not to be blocked by the other prism systems. As a result, the object can be accurately observed from various directions simultaneously.
