Solution Overview
Problem
Imaging apparatuses with insertable and removable shutter mechanisms face structural challenges, including size restrictions and complex insertion/removal mechanisms, which impair production efficiency and maintenance freedom in structural design.
Innovation Solution
An imaging apparatus design featuring an optical lens, imaging element, and a supporting member that forms a space for an illumination adjustment unit, allowing for easier integration and positioning of the unit without requiring optical axis adjustments, and includes a seal member for enhanced dust-proof and light-blocking properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the size of the illumination adjustment unit is enlarged to accommodate larger light blocking mechanisms like mechanical shutters, then the functional capability is improved, but the structural complexity and difficulty of integration increase
Solution Approach 1:
The imaging apparatus is divided into distinct modular components: the supporting member with its first and second supporting parts, the coupling part, and the illumination adjustment unit. This segmentation allows each component to be designed and manufactured independently, then assembled together, reducing overall structural complexity while accommodating larger illumination adjustment units.
Solution Approach 2:
The illumination adjustment unit is positioned in a third axial direction orthogonal to the first axial direction (optical axis) and second axial direction, creating a spatial arrangement that accommodates larger units without interfering with the optical path or other components.
2Ease of repair
If the illumination adjustment unit is made detachable and insertable for easier maintenance, then the ease of repair is improved, but the insertion/removal mechanism becomes more complex
Solution Approach 1:
The detachable design separates the illumination adjustment unit from the supporting member, allowing independent maintenance and replacement of the illumination adjustment unit without disassembling the entire imaging apparatus, thus simplifying repair procedures.
Solution Approach 2:
The supporting member is pre-configured with a space and coupling structure that anticipates the insertion of the illumination adjustment unit, enabling straightforward assembly without requiring complex alignment or adjustment procedures during maintenance.
3Ease of manufacture
If the supporting member forms a dedicated space for the illumination adjustment unit, then the ease of manufacture is improved, but the device complexity increases
Solution Approach 1:
The supporting member is designed as a separate component with an integrated space formation, allowing it to be manufactured independently using standard manufacturing processes, then assembled with other components. This segmentation simplifies manufacturing while the integrated space design prevents excessive complexity.
Solution Approach 2:
The supporting member serves multiple functions: it supports the optical lens, supports the imaging element, forms the space for the illumination adjustment unit, and provides the coupling structure. This multi-functionality reduces the need for additional separate components, thereby reducing overall device complexity while maintaining ease of manufacture.

AI summary
An imaging apparatus has an optical lens having an optical axis in a first axial direction; an imaging element facing the optical lens in this direction; an illumination adjustment unit having an illumination adjustment part adjusting a luminous flux incident on the imaging element from the optical lens, with the illumination adjustment part being arranged on the optical axis by being inserted between the optical lens and the imaging element in a second axial direction orthogonal to the first axial direction; and a supporting member having a first supporting part supporting the lens, a second supporting part supporting the imaging element, and a coupling part coupling the first and second supporting parts to each other, the supporting member being configured to form a space, into which the illumination adjustment unit is inserted in a third axial direction orthogonal to the first and the second axial directions.
