Bracket Gravity Center Alignment for Automated Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional brackets for electronic devices often bow or incline during attachment to the chassis, leading to instability and requiring manual screw fastening, which increases process time and prevents automated screw fastening.
Innovation Solution
A bracket design featuring a bracket fixing hole, clamp hole, and notches that position the bracket correctly on the mounting part, with the gravity center aligned with the bracket fixing hole to prevent inclining and allow automated screw fastening, and an elongate bracket fixing hole to accommodate the screw securely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional bracket is placed to the bracket mounting part, then the bracket can be attached to the chassis, but the bracket bows or inclines due to vibrating motion, causing instability
Solution Approach 1:
The bracket is designed with notches and positioning protrusions that enable preliminary positioning before screw fastening. The notches on the bracket engage with positioning protrusions on the mounting part, pre-establishing the correct position and orientation before the fastening process begins, thereby preventing bowing during attachment
Solution Approach 2:
The bracket features asymmetric design elements including notches at specific positions and an elongate bracket fixing hole oriented in a particular direction. This asymmetric configuration ensures that the bracket can only be positioned in the correct orientation, preventing incorrect placement and bowing during the fastening process
2Extent of automation
If the bracket is inclined or dropped during placement, then manual screw fastening is required, but this increases process time and prevents automated screw fastening
Solution Approach 1:
The bracket incorporates notches and positioning protrusions that enable preliminary positioning before screw fastening. This pre-positioning ensures the bracket is correctly aligned and stable before automation begins, allowing automated screw fastening devices to operate efficiently without manual intervention
Solution Approach 2:
The bracket's own structure (notches and positioning protrusions) performs the positioning function that would otherwise require manual adjustment. The bracket self-aligns with the mounting part through the engagement of these features, eliminating the need for manual positioning and enabling automated fastening
3Ease of manufacture
If the bracket is placed without proper positioning features, then the placement process is simple, but the bracket may be dropped from the mounting part
Solution Approach 1:
The bracket is divided into functional segments including notches for positioning, a bracket fixing hole for fastening, and a clamp hole for cable management. This segmentation allows each feature to perform its specific function independently, maintaining both simplicity and reliability
Solution Approach 2:
The notches and positioning protrusions act as intermediary elements between the bracket and the mounting part. These features mediate the connection by providing precise positioning and alignment, ensuring reliable attachment without complicating the overall placement process

AI summary
A bracket fixing hole that is configured to insert a screw part of a bracket fixing screw that is configured to mount the bracket to a bracket mounting part, a clamp hole that is configured to mount a cable clamp, and at least two notches that are configured to position the bracket to the at least two convex parts of the bracket mounting part are formed to a bracket. The bracket fixing hole and the clamp hole are faced on the opposed sides in such a manner that a first line segment that connects parts of the two notches is disposed between the holes. A second line segment that connects a center of the bracket fixing hole and a center of the clamp hole and the first line segment generally bisect each other at right angles. A gravity center is disposed on the side of the bracket fixing hole to the first line segment.
