Solution Overview
Problem
Existing optical adaptor mounting metal fittings lack sufficient spring elasticity to securely attach optical adaptors to panels through mounting holes of varying widths, leading to wobbling issues due to limited elastic deformation capacity and design constraints.
Innovation Solution
A thin metal plate mounting fitting with a joining plate and facing side plates, featuring elastic click engagements and free front ends, allowing for oblique extensions that deform and engage with the panel and adaptor to provide enhanced elastic deformation and secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the curved engagement is integrally connected to the outer frame at the top and bottom ends, then the structure is simplified and easier to manufacture, but the elastic deformation capacity is significantly reduced, yielding insufficient spring elasticity
Solution Approach 1:
The side plate is divided into multiple independent elastic engagements (first elastic engagement and second elastic engagement) that are not integrally connected to the outer frame. Each elastic engagement can deform independently, significantly increasing the overall elastic deformation capacity while maintaining manufacturing simplicity through modular design
Solution Approach 2:
The elastic engagements are designed with free ends that allow dynamic deformation during mounting and operation. The first elastic engagement can deform to engage with the mounting hole inner surface, while the second elastic engagement can deform to engage with the optical adaptor sidewall, providing adaptive spring elasticity
2Area of stationary object
If the panel mounting hole has a small width and the gaps between the mounting hole inner surfaces and adaptor sidewalls are small, then the mounting is more compact, but the curved engagement cannot be elastically deformed to be flat and inserted in the mounting hole
Solution Approach 1:
The first elastic engagement is designed with a free end that can dynamically deform to accommodate varying mounting hole widths. When the hole is narrow, the engagement deforms to a flatter state to pass through; when the hole is wide, it deforms to engage with the inner surface, ensuring secure mounting in both scenarios
Solution Approach 2:
The elastic engagement's deformation state changes based on the mounting hole dimensions. The free end allows the engagement to adjust its shape parameter (curvature) to match the specific gap size, enabling insertion and secure engagement across a range of mounting hole widths
3Area of stationary object
If the gaps between the mounting hole inner surfaces and adaptor sidewalls are large, then the mounting is more accessible, but the curved engagement is not elastically engaged with the inner surface of the mounting hole
Solution Approach 1:
The first elastic engagement dynamically adjusts its deformation state based on the mounting hole width. When gaps are large, the engagement deforms to fully contact and engage with the inner surface of the mounting hole, ensuring secure attachment and preventing wobbling despite the larger clearance
Solution Approach 2:
The engagement's contact parameter (degree of engagement with inner surface) changes in response to the gap size. Larger gaps result in greater elastic deformation and increased contact area with the mounting hole inner surface, maintaining reliable engagement across varying dimensions
4Device complexity
If the outer frame is in the form of a frame, then the structure is simplified, but it is difficult to be elastically deformed, yielding almost no spring elasticity
Solution Approach 1:
The rigid frame structure is segmented into multiple flexible elastic engagements with free ends. Each segment can independently deform elastically, transforming the overall structure from rigid to flexible while maintaining the simple frame-like configuration. This provides significant spring elasticity without increasing structural complexity
Solution Approach 2:
The elastic engagements are designed as thin, flexible metal plate structures that can undergo significant elastic deformation. These flexible elements replace the rigid frame concept while maintaining structural simplicity, providing the necessary spring elasticity for secure mounting

AI summary
There is provided an optical adaptor mounting metal fitting for mounting an optical adaptor through a panel without wobbling and an optical adaptor with the mounting metal fitting attached thereto. The optical adaptor mounting metal fitting includes a joining plate and a pair of facing side plates extending from either side of the joining plate nearly at a right angle, the side plates each have an elastic click engagement formed by cutting out and raising a middle part of the side plate so that a front end thereof closely faces the panel. A first side plate piece that is on a joining plate side of the elastic click engagement, and a second side plate piece that is on an opposite side of the elastic click engagement to the first side plate piece, and first elastic engagements each obliquely extend from a front end of the second side plate piece toward the joining plate and the optical adaptor.
