Cone and Clamp Assembly for Screen Cable Retention During Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen assembly systems face issues with cable detachment from the cone during transportation or installation, particularly due to inadequate clamping mechanisms that are costly, difficult to replace, and not suitable for smaller screens, leading to noise and friction problems.
Innovation Solution
A cone and clamp assembly with a clamp configured to hold the line member securely to the cone using an adjustable element that rotates the clamp into an engaged or disengaged position, featuring a drive plate and cone plate mechanism to ensure reliable attachment and detachment of the line member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a screen assembly is designed to be easily adjustable and removable, then ease of operation is improved, but structural stability and strength deteriorate
Solution Approach 1:
The screen assembly is divided into separate components: a screen member with aperture edges and a separate frame structure. This segmentation allows the screen to be easily inserted and removed through the aperture opening while the frame provides structural support, resolving the contradiction between ease of operation and structural stability.
Solution Approach 2:
The screen member is designed to be nested within or attached to the frame structure. The screen can be positioned within the frame opening and secured, allowing easy removal and reinstallation while maintaining structural integrity when assembled, thus balancing adjustability with strength.
2Device complexity
If a screen assembly uses a simple frame structure, then device complexity is reduced, but manufacturing precision and alignment difficulty increase
Solution Approach 1:
The frame structure incorporates specific local features such as aperture edges with defined geometries that interface with the screen member. These localized precision features are concentrated only where needed (at the aperture opening) rather than throughout the entire frame, maintaining overall simplicity while achieving necessary alignment precision.

AI summary
A cone and clamp assembly for a screen assembly comprises a substantially vertical supporting member about which a screen can be wound/unwound, a cone associated with at least one end of the supporting member and rotatable with the supporting member and at least one line member that can be wound onto and off the cone. The cone and clamp assembly comprises a clamp configured to hold the at least one line member relative to an external surface of the cone in an engaged position during transportation of the screen assembly or prior to operation of the screen assembly, a drive plate engaged with a pivot pin of the clamp, a cone plate coupled to the cone through the drive plate and the clamp, and an adjustable element coupled between the cone plate and the drive plate. Adjustment of the adjustable element in a first direction rotates the clamp toward the external surface of the cone and adjustment of the adjustable element in a second direction rotates the clamp away from the external surface of the cone.
