Bracket With Rotatable Fastener For Optical Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing method of attaching optical units to racks using screws is time-consuming and labor-intensive, especially when multiple units need to be attached.
Innovation Solution
A bracket system comprising a bracket body with a protrusion and a rotatable fastener with hooks that temporarily fix the optical unit to the rack, allowing for easy attachment without screws, by inserting the protrusion into a hole and rotating the fastener to grip the rack's angle, providing a secure locking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to fasten brackets to racks, then reliable fixation is achieved, but attachment time and labor increase significantly
Solution Approach 1:
The patent replaces the screw-fastening mechanical system with a snap-fit mechanical system. The bracket includes positioning protrusions that engage with corresponding positioning holes in the rack, and elastic components that provide snap-fit engagement, eliminating the need for screws and significantly reducing attachment time while maintaining reliable fixation.
Solution Approach 2:
The bracket design incorporates elastic components (such as elastic plates or springs) that automatically engage with the rack structure through snap-fit action. The elastic components deform during insertion and then rebound to lock the bracket in place, providing self-servicing fixation without requiring manual screw tightening operations.
2Quantity of substance
If multiple optical units are attached to racks, then rack capacity increases, but cumulative attachment time and labor effort increase proportionally
Solution Approach 1:
The bracket is designed as a modular component with distinct functional elements: positioning protrusions for alignment, elastic components for snap-fit engagement, and mounting holes for optical unit attachment. This segmentation allows for rapid, repetitive attachment operations when installing multiple optical units, as each bracket can be independently and quickly secured to the rack without affecting other attachment operations.
3Reliability
If traditional screw fastening is used, then secure attachment is achieved, but operation complexity and labor intensity increase
Solution Approach 1:
The patent replaces the multi-step screw fastening operation with a single-step snap-fit insertion operation. The positioning protrusions guide the bracket into correct alignment with the rack, and the elastic components automatically engage to secure the attachment, transforming a complex manual operation into a simple, intuitive motion that is easier to perform and requires less training.

AI summary
A bracket for attaching an optical unit to a rack is provided. The bracket comprises a bracket body and a fastener. The bracket body has a first wall including a first face and a second face opposite to the first face, and a protrusion extending in a direction intersecting with the first wall from the second face against the first face. The bracket body is provided with a hole penetrating through the first wall from the first face to the second face. The fastener is arranged to pass through the hole on the first wall and is configured to be rotatable with respect to the first wall. The fastener has a first hook including a holding surface substantially parallel to the second face. The holding surface of the first hook faces the second face to define a first gap between the holding surface and the second face of the first wall at least when the fastener rotates from an initial position to a first locking position.
