Two-Layer Press-Worked Camera Mount for Lens Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional camera mounts for interchangeable lens cameras, composed of a metal and synthetic resin, have high manufacturing costs due to the sintering method used for metal parts and weak claw portions made of synthetic resin, which compromise strength.
Innovation Solution
A two-layer camera mount design where both layers are made through press working of metal materials, with the second layer featuring lens attachment claw portions formed by press drawing, allowing for enhanced strength without increasing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the sintering method is used to manufacture metal parts of the camera mount, then the metal parts can be formed, but the manufacturing cost increases
Solution Approach 1:
The patent changes the manufacturing method from sintering to press working, which is a different processing parameter approach. Press working allows for lower manufacturing costs while producing metal parts with sufficient strength for the camera mount application, thereby resolving the contradiction between manufacturing cost and reliability
Solution Approach 2:
The patent adopts press working as a more cost-effective manufacturing method compared to sintering. This principle suggests using simpler, cheaper manufacturing processes when they can achieve the required functional performance, which is exactly what the patent does by replacing expensive sintering with affordable press working
2Strength
If the claw portion is made of synthetic resin, then the manufacturing cost is reduced, but the strength of the claw portion becomes weak
Solution Approach 1:
The patent creates a composite structure where the metal mount body is integrated with press-worked metal claw portions. This composite approach combines the strength benefits of metal with the cost-effectiveness of press working, eliminating the need for separate synthetic resin components while achieving both high strength and reasonable manufacturing cost
Solution Approach 2:
The patent merges the claw portion and the mount body into a single integrated metal component formed through press working. This merging eliminates the need for separate synthetic resin parts, thereby increasing the strength of the claw portion while maintaining manufacturing efficiency and cost-effectiveness
3Adaptability or versatility
If a two-piece mount structure is used, then the design flexibility is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent merges multiple functional elements (mount body, claw portions, and structural features) into a single press-worked metal component. This merging reduces manufacturing complexity by eliminating the need for assembling multiple separate parts, while still maintaining the design flexibility needed for interchangeable lens mounting
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The camera mount achieves increased strength and durability while maintaining cost-effectiveness by using press-worked metal layers with press-drawn claw portions, facilitating secure attachment and detachment of lenses without the limitations of traditional sintering methods.

AI summary
A camera mount consists of at least two layers which are laminated in an optical axis direction of an image-capturing lens. The camera mount is engaged with the image-capturing lens and detachably locks the image-capturing lens to a camera body. The camera mount includes a first mount layer; and a second mount layer, laminated on the first mount layer, made of a metal material and having a plurality of lens attachment claw portions configured to attach the image-capturing lens.
