Imaging Device Substrate Inclined Attachment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging apparatuses face challenges in accurately attaching imaging elements to optical systems, as they struggle to adjust both position and orientation without increasing the size of the substrate, and existing solutions either fail to adjust orientation or require numerous components that occupy space.
Innovation Solution
The imaging apparatus incorporates attachment portions with inclined surfaces and supports to securely attach the substrate at desired positions and orientations, allowing for precise alignment while minimizing the number of screws and maintaining a compact size by balancing rotational forces with opposing abutments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If four legs and four or more screws are used to fix the imaging element substrate, then the imaging element can be securely attached, but the space for attaching members increases, preventing the substrate from being made compact
Solution Approach 1:
The patent combines multiple attachment functions into a single integrated attachment portion structure. The attachment portion includes an attachment body with inclined surfaces and a screw hole, integrating the functions of positioning, orienting, and securing the imaging element substrate into one component rather than using separate legs and multiple screws.
Solution Approach 2:
The attachment portion serves multiple functions simultaneously: it provides mechanical support, enables angular adjustment through inclined surfaces, secures the substrate with a single screw, and maintains compact dimensions. This multi-functional design eliminates the need for multiple separate components.
2Measurement precision
If an eccentric screw is used to adjust the position of the imaging element substrate, then in-plane displacement can be achieved, but orientation adjustment is not possible
Solution Approach 1:
The attachment portion incorporates an inclined surface that enables dynamic angular adjustment of the imaging element substrate. By moving the attachment portion along the inclined surface, the substrate can be adjusted to different angles, providing adaptability for orientation correction while maintaining precise positioning capability.
Solution Approach 2:
The patent adds angular adjustment capability by introducing an inclined surface dimension. While traditional eccentric screws only provide in-plane displacement (two-dimensional adjustment), the inclined surface adds a third dimension of angular adjustment, enabling both position and orientation correction.

AI summary
An imaging apparatus includes a substrate (13) including an imaging element (16), one or two attachment portions (14) that attach the substrate (13) by screwing and are capable of inclining a board surface of the substrate (13), by screwing in a screw (18), relative to a plane (VP) perpendicular to an optical axis (OX) of an optical system that forms an optical image on the imaging element (16); and one or more supports (15) configured to abut the substrate (13) from an opposite direction to a screwing direction of the attachment portion (14) at any position, on the substrate (13), that rotates in the screwing direction of the attachment portion (14) when the board surface is inclined by screwing. As a result, an imaging apparatus that allows an imaging element to be installed at a desired position and orientation while reducing the size of the substrate is provided.
