Optical Unit Positioning via Triangular Support Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image processing apparatuses experience degradation in optical instrument positioning accuracy due to warping of the supporting member caused by uneven installation surfaces and the weight of the apparatus body, particularly when legs are provided in four points or three points forming a rough triangle.
Innovation Solution
The image processing apparatus is designed with protruding legs arranged in three points forming a triangle on the undersurface, supporting the optical unit in a similar triangular configuration, which minimizes warping and maintains high accuracy of optical instrument positioning, even under varying elevation conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If legs are provided in four points on the undersurface of the apparatus body, then the apparatus body is supported stably, but the supporting member (frame) easily warps due to differences of elevation on the installation surface, degrading the accuracy of positioning of the optical instruments
Solution Approach 1:
The patent divides the supporting function into two independent parts: (1) legs providing three-point support for the apparatus body, and (2) a separate supporting member for the optical unit that is positioned independently. This segmentation allows the optical unit's position to be determined without being affected by warping of the body-supporting frame, thereby maintaining positioning accuracy while ensuring apparatus stability.
Solution Approach 2:
The patent introduces an intermediary relationship where the optical unit is supported by a dedicated supporting member rather than directly by the body frame. This intermediary structure isolates the optical positioning system from the warping effects caused by uneven installation surfaces, allowing the legs to provide stability while the supporting member maintains positioning accuracy.
2Device complexity
If the optical unit is supported by the body structure, then the apparatus is compact, but the accuracy of positioning of the optical instruments is degraded by the warp of the supporting members caused by the weight of the apparatus body
Solution Approach 1:
The patent segments the support functions by providing three separate supporting members for the optical unit instead of relying on a single integrated body structure. These three supporting members form a triangle that is positioned independently, allowing the optical unit to be supported without being affected by warping of the main body frame, thus maintaining positioning accuracy while keeping the structure compact.
Solution Approach 2:
The patent applies local quality by positioning the three supporting members at specific locations that form a triangle in about the same direction as the triangle formed by the legs. This localized arrangement ensures that the optical unit is supported at optimal points that minimize the impact of body frame warping, maintaining positioning accuracy in the critical optical region.
3Stability of the object's composition
If legs are provided in three points forming a rough triangle, then the apparatus body is supported, but the supporting member (frame) may warped because of its own weight, degrading the accuracy of positioning of the optical instruments
Solution Approach 1:
The patent segments the support system into legs for body support and separate supporting members for optical unit support. By providing three supporting members that form a triangle independent of the body frame, the optical unit's position is determined without being affected by warping of the body-supporting frame, maintaining positioning accuracy while ensuring stable support.

AI summary
An image processing apparatus having a structure in which the positioning accuracy of the optical instruments related to image processing are hardly influenced from the condition of the installation surface of the apparatus body. Near the edges of floor plate 60 forming the undersurface of the body of image processing apparatus A, four legs 61, 62, 63a, and 63b are provided in a protruding manner in three points forming generally a triangle, and optical unit X1 in which the optical instruments are mounted is supported by vertical positioning plate 6a or horizontal positioning plate 6a, which are a part of the apparatus body's structure, in three points forming a triangle in the same direction as the triangle formed by Legs 61, 62, and 63 in three points when viewed from underneath, and then, these three points are arranged in the position near each of the three points provided with legs 61, 62, and 63 when viewed from underneath.
