Board Attaching Structure With Bending Restriction Mechanisms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing board attaching structures in endoscope connectors face challenges in securely and accurately positioning and mounting secondary boards relative to primary boards, leading to potential misalignment and improper electrical connections.
Innovation Solution
A board attaching structure that includes a first board with a connector, a second board with a corresponding connector, a plate-like member acting as a shield case, and bending portions to restrict the posture and position of the second board, facilitating easy and accurate mounting through a guiding mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a plate-like member is used to cover the first board, then the second board is protected and positioned, but the complexity of the attaching structure increases
Solution Approach 1:
The plate-like member is segmented into functional zones: a covering portion that protects the first board, and bending portions that form restriction mechanisms. This segmentation allows each part to serve a specific function, achieving reliable positioning while maintaining structural clarity
Solution Approach 2:
The plate-like member merges multiple functions into a single component: it provides mechanical protection, positional restriction, and structural support simultaneously. This consolidation reduces the total number of parts needed while achieving multiple objectives
2Manufacturing precision
If bending portions are added to restrict posture and position, then the second board is accurately positioned, but the manufacturing complexity increases
Solution Approach 1:
The bending portions are pre-formed during the manufacturing of the plate-like member, establishing the restriction geometry in advance. This preliminary action ensures precise alignment capabilities are built into the structure itself, eliminating the need for complex post-assembly adjustments
Solution Approach 2:
The bending portions utilize controlled changes in the plate's geometric parameters (bend radius, angle, and position) to create effective restriction mechanisms. By optimizing these parameters, the structure achieves high positioning precision while remaining manufacturable using standard forming processes

AI summary
A board attaching structure includes a first board on which a first connector provided, a second board on which a second connector provided, a plate-like member extending parallel to the first board and covering at least part of an surface of the first board, a posture restricting portion formed by bending part of the plate-like member toward the first board and configured to restrict a posture of the second board with respect to the first board when the second connector is mounted on the first connector, and a position restricting portion formed by bending part of the plate-like member and configured to restrict a position at which the second board is arranged on the first board while the second connector is mounted on the first connector.
