Universal Flash Hot Shoe with Multi-Contact Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Different types of cameras have distinct hot shoe connectors with varying electrical contact locations and signal transmission, making external flashes incompatible across camera types, leading to user inconvenience and increased manufacturing costs.
Innovation Solution
A mechanism with two groups of electrical contacts on a connecting foot, designed to match and connect with multiple camera types, and a main control unit that determines the camera type and selects the appropriate flash control program for sending commands to the external flash.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If external flashes are designed with specific hot shoe connectors for different camera types, then compatibility with specific camera types is improved, but device complexity and manufacturing costs increase
Solution Approach 1:
The flash unit incorporates multiple groups of electrical contacts (first group for Canon cameras, second group for Nikon cameras) on a single hot shoe connector, enabling one flash to universally interface with multiple camera types. This eliminates the need for separate flash designs for different camera brands, reducing device complexity while maintaining broad compatibility.
2Adaptability or versatility
If multiple types of external flashes are manufactured for different camera types, then camera compatibility is improved, but manufacturing costs increase
Solution Approach 1:
By integrating multiple groups of electrical contacts into a single flash unit, the invention allows manufacturers to produce one universal flash model that can interface with multiple camera types (Canon and Nikon). This eliminates the need to manufacture separate flash models for different camera brands, significantly reducing manufacturing costs while maintaining broad camera compatibility.
3Ease of operation
If a single external flash is designed to work with multiple camera types, then user convenience is improved, but the structure of the hot shoe connector becomes more complex
Solution Approach 1:
The hot shoe connector is designed with multiple groups of electrical contacts that can interface with different camera types. The first group of contacts corresponds to Canon camera hot shoes, while the second group corresponds to Nikon camera hot shoes. This multi-functional connector design enables a single flash to work with multiple camera brands, improving user convenience despite the increased structural complexity of the connector.
Solution Approach 2:
The flash unit acts as an intermediary device that bridges different camera systems (Canon and Nikon) through its multiple groups of electrical contacts. By incorporating both contact configurations in one unit, it mediates between incompatible camera hot shoe designs, allowing a single flash to interface with multiple camera types without requiring separate flash models for each camera brand.

AI summary
The present invention relates to a mechanism and system for attaching an external flash to a camera, and a flash. The connection mechanism comprises: a body, a connecting foot and at least two groups of electrical contacts for touching contacts of hot shoes of at least two differing types of cameras for connecting an external flash control unit; when a flash provided with the mechanism for attaching an external flash to a camera as disclosed in the present invention is mounted on a camera, the corresponding group of electrical contacts touch each other to transmit signals. Since at least two groups of electrical contacts are provided, the flash is capable of being applied to cameras of two differing types, and further facilitating users and saving costs.
