Paint Shield Pivot Mechanism for Angular Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paint shields are limited in their ability to adjust angularly and pivot without manual adjustment, making them inefficient for use at elevated heights or large distances, and they lack a convenient storage solution, often requiring disassembly and increasing the risk of parts being lost or misplaced.
Innovation Solution
A paint shield with a pivot member connected to an extension handle that allows angular positioning without manual adjustment of tightening members, and a storage location for the pivot member and handle, enabling efficient storage as a single unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a paint shield uses fixed fastening screws to secure the shield plate to the handle, then the shield can be assembled, but it cannot be adjusted angularly or pivoted during use
Solution Approach 1:
The patent applies the dynamics principle by replacing fixed fastening screws with a pivot mechanism that allows the shield plate to rotate angularly relative to the handle. The pivot member enables dynamic adjustment of the shield's angle during use, transforming a static connection into a dynamic, adjustable joint that adapts to different painting positions and surface contours.
2Volume of moving object
If the paint shield is separated into constituent parts for storage, then it becomes more compact, but the parts are prone to being lost or misplaced
Solution Approach 1:
The patent applies the nested doll principle by designing a storage location within the handle that accommodates the pivot member and shield plate. The handle contains a recess or cavity where the detachable components can be nested during storage, allowing the shield to be compacted into a small volume while maintaining secure retention through the integrated storage structure.
3Ease of operation
If the paint shield requires manual adjustment of tightening members for angular positioning, then it can be adjusted, but it cannot be pivoted freely at elevated heights during use
Solution Approach 1:
The patent applies the self-service principle by designing a pivot mechanism that allows the shield plate to be adjusted angularly without requiring manual manipulation of tightening members during use. The pivot member enables the shield to self-adjust to different angles through its rotational capability, freeing the user's hands for painting operations while maintaining ease of angular positioning.

AI summary
A paint shield for preventing the misapplication of coating material comprises a shielding member having a leading edge and a base member, an extension handle for enabling a user to hold the leading edge of the paint shielding member against a surface, a pivot member connected to the base member for angularly positioning the shielding member, and a storage location positioned in said base member for storing the pivot member and the extension handle when the pivot member is selectively removed from the base member. The pivot member preferably includes two walls having at least one frictional pad disposed on an inner surface of each wall for frictionally engaging the base member and allowing a user to angularly pivot the shielding member without loosening the pivot member.
