Accessory Shoe Connecting Device Mechanical Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image pickup apparatuses with accessory shoe devices face challenges in achieving sufficient mechanical strength while accommodating multiple connection terminals and parts, leading to restricted connecting structures and potential damage from external forces.
Innovation Solution
A connecting device with an engagement member that slides into the accessory shoe device, a holding member, fastening members, and a connecting plug with multiple terminals, where the fastening members are spaced apart to allow for increased mechanical strength and secure attachment, and a lock pin or synchronizer contact for position regulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of connection terminals is increased to accommodate diverse accessory functions, then the compatibility and functionality of accessories are improved, but the mechanical strength of the connecting structure deteriorates due to restricted connecting structures
Solution Approach 1:
The patent transitions from a planar arrangement of connection terminals to a three-dimensional configuration by stacking terminal rows in the depth direction. This allows multiple terminals to be arranged without increasing the footprint area, thereby maintaining mechanical strength while accommodating diverse accessory functions. The engagement member includes multiple rows of terminals extending in the width direction, with corresponding terminal rows stacked in the depth direction, creating a multi-layered connection structure.
Solution Approach 2:
The patent implements a nested arrangement where terminal rows are positioned within the engagement member structure in a compact, space-efficient manner. The terminals are integrated into the engagement member body, with terminal rows nested within the overall geometry of the connecting device. This nesting approach maximizes the use of available space while maintaining structural integrity and mechanical strength.
2Quantity of substance
If the area for arranging connection terminals and parts is increased, then the number of connection terminals is improved, but the connecting structure becomes restricted and mechanical strength deteriorates
Solution Approach 1:
The patent utilizes the depth dimension to arrange terminal rows, allowing multiple terminals to be positioned without expanding the width or length of the engagement member. This three-dimensional arrangement enables a high quantity of connection terminals while maintaining a compact footprint that preserves the connecting structure's mechanical strength.
Solution Approach 2:
The patent divides the connection terminals into multiple separate rows arranged in the width direction, with corresponding rows stacked in the depth direction. This segmentation allows each terminal row to be independently positioned and connected, optimizing space utilization while maintaining structural integrity. The engagement member is effectively segmented into multiple functional layers, each contributing to the overall connection capacity without compromising strength.

AI summary
A connecting device of an accessory by which improvement in mechanical strength is compatible with arrangements of many connection terminals. The connecting device is detachably attachable to an accessory shoe device of an electronic apparatus. An engagement member is attachable to the accessory shoe device by sliding in a first direction. A holding member is fixed to the engagement member by fastening members. A connecting plug has connection terminals and is arranged at a front part in the first direction of the holding member. The fastening members are arranged at positions that are spaced apart from each other in a second direction that perpendicularly intersects with the first direction. A width of the holding member is shorter than a width of the engagement member in the second direction, and the connection terminals are arranged in an area between the positions of the fastening members.
