Reinforcing Member for Shake Detection Unit Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera systems with shake detection units face issues with erroneous image stabilization due to external forces causing posture changes in the shake detection unit, leading to incorrect vibration detection and poor image quality.
Innovation Solution
An image capturing apparatus with a reinforcing member disposed between the exterior unit and the main body to reduce deformation from external forces, ensuring accurate shake detection and stabilization by fixing the shake detection unit in place.

Engineering Contradiction Analysis
1Object-affected harmful factors
If the shake detection unit is held by a cushioning material to reduce shutter vibration transmission, then shutter vibration influence is reduced, but the shake detection unit posture changes under external force
Solution Approach 1:
The patent applies beforehand cushioning by using a cushioning material positioned between the shake detection unit and the main body to preemptively absorb shutter vibration before it reaches the detection unit. This resolves the contradiction by providing vibration isolation while the reinforcing member maintains posture stability under external forces.
Solution Approach 2:
The patent introduces a reinforcing member as an intermediary structural element between the exterior unit and the main body. This mediator provides mechanical support to maintain the shake detection unit's posture stability under external force, while allowing the cushioning material to continue its vibration isolation function.
2Device complexity
If no countermeasure is taken against posture change, then device complexity is reduced, but image stabilization performance deteriorates
Solution Approach 1:
The patent segments the mounting structure into distinct functional components: a cushioning material layer for vibration isolation and a reinforcing member for posture stabilization. This segmentation allows each component to perform its specific function efficiently without requiring complex integrated solutions.
Solution Approach 2:
The patent employs a composite structural approach by combining the cushioning material (for vibration absorption) with the reinforcing member (for mechanical support). This composite structure achieves both vibration isolation and posture stability without significantly increasing device complexity.

AI summary
The image capturing apparatus includes an exterior unit fixed to a main body of the image capturing apparatus, and a shake detection unit that is disposed in an accommodation area located in the exterior unit, and is configured to detect a shake of the image capturing apparatus. The image capturing apparatus further includes a reinforcing member that is disposed in the accommodation area, and reduces deformation of the exterior unit due to an external force applied thereto. The reinforcing member is disposed between the exterior unit and the main body when the external force is applied.
