Shoe Device Sliding Engagement and Perpendicular Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shoe devices for electronic apparatus accessories, such as cameras, lack mechanical strength and convenience when used independently of the camera, as they prioritize communication terminals over attachment mechanisms, making them user-unfriendly and incompatible with general camera tripods.
Innovation Solution
A shoe device with a sliding engagement mechanism, a holding member, and a connection member with terminals arranged perpendicularly, allowing attachment to and detachment from the accessory shoe device, and featuring a tripod internal thread for secure attachment to camera tripods, ensuring mechanical strength and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the shoe device increases the number of connection terminals to support diverse accessory functions, then the communication capability is improved, but the area available for mechanical attachment structures is reduced
Solution Approach 1:
The connection terminals are arranged in a direction perpendicular to the sliding direction of the engagement member, utilizing the third dimension (depth) rather than competing for surface area. This allows both multiple terminals and adequate attachment area to coexist by distributing elements across different spatial dimensions.
2Adaptability or versatility
If the shoe device prioritizes arrangement of communication terminals and connection parts, then the communication function is improved, but the mechanical strength for independent use is reduced
Solution Approach 1:
The shoe device is divided into distinct functional segments: the engagement member for mechanical attachment, the holding member for structural support, and the connection member for communication. This segmentation allows each component to be optimized for its specific function while maintaining overall structural integrity.
Solution Approach 2:
Different regions of the shoe device are assigned different structural qualities - the engagement member and holding member use robust mechanical structures for strength, while the connection member provides electrical connectivity. This local differentiation of material properties and structural characteristics resolves the contradiction between mechanical strength and communication functionality.
3Device complexity
If the shoe device is designed without tripod internal thread for compactness and terminal arrangement, then the device complexity is reduced, but the ease of operation for independent use is worsened
Solution Approach 1:
The shoe device incorporates a tripod internal thread in addition to its primary camera accessory shoe function, making it universally compatible with both camera systems and general camera tripods. This multi-functionality allows the same device to serve multiple purposes without requiring separate specialized equipment.

AI summary
A shoe device of an accessory that secures necessary functions and mechanical strength when the accessory is used with attaching to an electronic apparatus and that improves convenience during use when the accessory is used without attaching to an electronic apparatus. An engagement member is attachable to and detachable from an accessory shoe device of an electronic apparatus by sliding in a first direction. A holding member holds the engagement member. An attachment part is provided in the engagement member or the holding member and allows attachment of a member different from the accessory shoe device. A connection member has connection terminals arranged in a second direction that intersects perpendicularly with the first direction and is arranged in a front of the holding member in the first direction. The attachment part is provided behind the connection terminals in the first direction.
