Rotating Retainer Assembly for Tool-Free Secure Equipment Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor communication equipment installation methods are difficult and time-consuming, requiring tools and lacking security features to prevent theft.
Innovation Solution
A tool-less retainer assembly comprising a bracket, base, plate, and security pin, where the plate rotates to secure fasteners and the security pin locks the plate in position, allowing easy installation and theft resistance without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If brackets are fixed with bolts and nuts or steel band clamps, then the installation is secure, but the installation process is difficult and time-consuming
Solution Approach 1:
The retainer assembly is divided into multiple functional components: a bracket for mounting, a rotatable plate with fastener-receiving apertures, and a security pin mechanism. This segmentation allows each component to perform its specific function independently, enabling quick assembly without complex fastening operations.
Solution Approach 2:
The plate is designed to rotate from a first position to a second position, transforming the static bracket structure into a dynamic assembly system. This rotation enables the fastener apertures to align automatically, facilitating tool-less installation while maintaining secure fastening when locked in position.
2Ease of manufacture
If traditional bracket systems are used, then the equipment can be installed, but there are no security or theft-resistant features
Solution Approach 1:
The security pin is pre-configured in the base and the plate includes a corresponding aperture for pin reception. This preliminary arrangement ensures that once the plate is rotated to the second position, the security pin automatically engages to lock the plate, providing theft resistance without requiring additional installation steps.
Solution Approach 2:
The security pin acts as an intermediary element between the base and the rotatable plate. It mediates the locking function by physically blocking the plate's rotation back to the first position, thereby providing security while maintaining the simplicity of the overall assembly process.
3Reliability
If installers hold electronic systems in the air to install brackets, then the brackets can be secured, but the process becomes difficult and time-consuming
Solution Approach 1:
The rotatable plate with aligned fastener-receiving apertures enables the bracket assembly to self-align and self-secure the electronic device. The device can be placed directly onto the bracket, and the rotating plate automatically positions the fasteners, eliminating the need for installers to manually hold and position components in the air.

AI summary
A retainer assembly includes a bracket, a base, a plate and a security pin. The bracket includes a front section of the bracket that forms apertures configured to each receive a fastener. The base includes a projection. The plate is located between the base and the bracket. The plate forms apertures configured to each receive a fastener. The plate further forms an aperture being configured to receive the projection extending from the base. The plate rotates in the retainer assembly from a first position to a second position. The security pin is securely mounted on the base. The security pin moves from a first position to a second position to inhibit the plate from rotating from its second position back to its first position.
