Solution Overview

Problem

Conventional camera bodies face challenges in downsizing while preventing light leakage due to gaps between the lens mount opening and the flare cutter, which affects the camera's overall size and optical performance.

Innovation Solution

The camera body design includes a flare cutter with an octagonal opening and a shutter unit with a smaller opening, positioned to minimize light leakage by optimizing the placement of the control board and shutter unit relative to the flare cutter, allowing for a compact camera body without overlapping components that could cause light leakage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the camera body is downsized, then the overall size is reduced, but light leakage occurs due to gaps between the lens mount opening and the flare cutter

Engineering Contradiction:

Improvecamera body sizeVSAvoidlight leakage

Core Design Contradiction:

Volume of moving objectVSObject-affected harmful factors

Solution Approach 1:

The control board is positioned within the flare cutter structure, utilizing the existing space efficiently. The control board is disposed on the second face of the flare cutter opposite the first face, and when viewed from the object side, the control board does not overlap with the shutter unit, allowing compact arrangement without increasing overall camera body size while preventing light leakage

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The control board is oriented in a different spatial dimension relative to the shutter unit. By positioning the control board on the opposite face of the flare cutter and ensuring it does not overlap with the shutter unit when viewed from the object side, the design utilizes three-dimensional space to prevent light leakage paths without increasing the camera body's external dimensions

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Object-affected harmful factors

If the control board and shutter unit are positioned to prevent overlap, then light leakage is prevented, but the camera body size increases

Engineering Contradiction:

Improvelight leakage preventionVSAvoidcamera body size

Core Design Contradiction:

Object-affected harmful factorsVSVolume of moving object

Solution Approach 1:

The control board is integrated with the flare cutter structure by positioning it on the second face of the flare cutter. This merging of the control board with the flare cutter assembly allows the components to occupy the same spatial region without overlapping with the shutter unit, preventing light leakage while maintaining a compact camera body size

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A camera body includes a flare cutter, a front case, and a control board. The flare cutter includes a first opening. The front case is disposed facing a first face of the flare cutter, and includes a second opening at a position facing the first opening. The control board is disposed on a second face of the flare cutter that is opposite the first face. When the flare cutter is viewed from outside of the front case, a part of the control board does not overlap with the flare cutter.
