Linear Actuator Barrier Assembly for Secure Press-Fit Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety gates face challenges in ease of installation and connection strength, which are critical for securing barriers effectively, particularly in preventing child and pet access to unsafe areas.
Innovation Solution
The development of a barrier assembly with linear actuator extensions that include a base housing, driving member with a threaded lead screw, worm gear, and worm, allowing for easy installation and secure fixation by press-fitting against surfaces, with configurations such as gear rack and pinion or worm systems to prevent movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional safety gate mounting methods are used, then installation is simple, but connection strength is insufficient
Solution Approach 1:
The mounting system is divided into separate functional components: a mounting bracket with press-fit anchors for wall attachment, and a linear actuator extension with separate mounting plates for gate attachment. This segmentation allows each component to be optimized independently - the anchors provide strong wall connection while the mounting plates enable easy gate attachment and adjustment.
Solution Approach 2:
The linear actuator extension includes pre-positioned mounting plates and adjustment mechanisms that are prepared in advance during manufacturing. This preliminary preparation allows installers to simply attach the pre-configured mounting components to the gate and wall without complex assembly steps, significantly easing installation while maintaining strong connections.
2Strength
If the barrier assembly uses a secure fixation mechanism, then connection strength is improved, but device complexity increases
Solution Approach 1:
The linear actuator extension incorporates self-aligning mounting plates with pre-drilled holes and self-positioning features that automatically align with corresponding wall openings during installation. The press-fit anchors self-expand upon insertion to create secure fixation without requiring additional fastening operations, reducing complexity while maintaining strength.
Solution Approach 2:
The mounting function is merged with the linear actuator extension structure itself. The mounting plates are integrated into the actuator housing, and the press-fit anchors are incorporated as part of the mounting assembly rather than separate components. This merging reduces the number of separate parts and simplifies the overall installation process while providing secure fixation.

Function Achieved in This Case
The linear actuator extensions provide a secure and easy-to-install solution for safety gates, ensuring effective prevention of unauthorized access by distributing pressure and withstanding internal compression forces, thus enhancing safety and usability.

AI summary
A linear actuator extension assembly having a base housing, a driving member and a driven member having a housing. The driving member has a driving surface and a threaded lead screw disposed within the base housing. The driving surface is rotated about a first axis to actuate the threaded lead screw, thereby rotating the threaded lead screw about a second axis substantially orthogonal to the first axis. The rotation of the threaded lead screw translates the driven member housing relative to the base housing.
