Camera Strap Buckle with Slit and Protrusion for Springless Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera strap fixation systems are unreliable and costly to manufacture, often relying on springs that can break or fail, leading to ineffective attachment and detachment of the camera strap.
Innovation Solution
A buckle system with a plate featuring a slit and protrusions between holes, allowing secure attachment and detachment without a spring, utilizing a slit to prevent undesired removal of the button, and a button design with a cylindrical surface and groove for improved usability and manufacturing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spring is used to prevent button displacement in existing fixation systems, then the button can be retained in the hole, but the spring may break or its fixation may change, rendering the system unreliable
Solution Approach 1:
The invention extracts and removes the spring from the fixation system entirely. Instead of using a spring to prevent button displacement, the patent uses a purely geometric solution with two holes positioned at different depths and a protrusion on the button that interacts with the hole geometry to provide retention without any elastic components.
Solution Approach 2:
The invention replaces the expensive and potentially unreliable spring mechanism with simple, inexpensive geometric features - specifically the two-hole configuration and protrusion design that can be easily manufactured into the plate and button components without requiring additional parts.
2Ease of manufacture
If existing fixation systems use spring mechanisms, then button retention is achieved, but the manufacturing cost increases and manufacturing complexity increases
Solution Approach 1:
The spring component is completely extracted from the system, eliminating the need for spring manufacturing, assembly, and maintenance while improving reliability through a simpler geometric retention mechanism.
Solution Approach 2:
The invention merges the retention function into the basic geometric structure of the plate and button components themselves. The two-hole configuration and protrusion are integrated directly into the molded or machined parts, eliminating the need for separate spring components and their associated assembly steps.
3Device complexity
If a single hole is used in the buckle, then the structure is simple, but the button cannot be securely retained without additional components like springs
Solution Approach 1:
The single hole is segmented into two distinct holes positioned at different depths within the plate. This segmentation creates a geometric retention mechanism where the first hole receives the button and the second hole, positioned deeper, prevents complete removal while allowing secure attachment through the interaction of the button's protrusion with the hole geometry.

AI summary
This buckle for a fixation system of a strap to a camera includes a plate and a means for attaching the plate to a strap, the plate including a first hole, a second hole and a protrusion located between the first and second holes. A button may be received in the second hole only by inserting it in the first hole and then moving it from the first hole into the second hole, and removed from the buckle only by moving it from the second hole into the first hole and then removing it from the first hole. The plate further includes a slit extending from the second hole towards an outer edge of the plate.
