Curved Camera Shoe Extension for Noise and Red-Eye Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera shoe designs make it difficult to maintain an adequate distance between accessories like microphones and flash devices and the camera body, leading to noise pickup and red-eye effects during image capture.
Innovation Solution
A camera shoe extension with a curved support arm that attaches to the camera body, allowing accessories to be positioned at a greater distance, featuring a detachable shoe attachment section with a clamp ring and a fitting section for cords, enabling the microphone and flash devices to be used while minimizing noise and red-eye issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the microphone assembly is attached to the camera shoe formed on the camera body, then the accessory can be securely mounted, but it becomes difficult or impossible to keep an adequate distance between the microphone assembly and the camera body, leading to noise pickup
Solution Approach 1:
A support arm is introduced as an intermediary component between the camera body and the microphone assembly. The support arm extends from the camera shoe and positions the microphone at a greater distance from the camera body, effectively reducing noise pickup while maintaining secure mounting capability
Solution Approach 2:
The support arm utilizes the vertical dimension by curving upward from the camera shoe, allowing the microphone to be positioned higher and further away from the camera body in three-dimensional space, thereby increasing the separation distance without interfering with the camera's horizontal footprint
2Object-affected harmful factors
If the flash device is mounted on the camera shoe of the camera body, then the accessory can be securely attached, but it is not possible to keep an adequate distance between the flash device and the camera body, causing red-eye effect
Solution Approach 1:
The support arm serves as a mediator that positions the flash device away from the camera body. By mounting the flash on the extended support arm rather than directly on the camera shoe, adequate distance is maintained to prevent red-eye effect while preserving secure attachment capability
Solution Approach 2:
The support arm is curved into an arcuate shape, allowing it to extend outward and upward from the camera shoe in a smooth curve. This curved configuration efficiently maximizes the distance between the flash device and camera body while maintaining a compact overall structure
3Length of stationary object
If a straight support arm is used to extend the camera shoe, then the distance can be increased, but the structure becomes rigid and difficult to adjust for different accessory positions
Solution Approach 1:
The support arm incorporates a hinged joint that allows it to pivot and adjust its angle. This dynamic feature enables the support arm to adapt to different accessory positions and orientations while maintaining the extended distance from the camera body, providing both stability and versatility
