Squeegee Washer Attachment Mechanism for Joined Handle and Back Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing squeegees do not allow for the attachment of a washer to the squeegee head when the handle head and back plate are joined, limiting the versatility and functionality of the tool.
Innovation Solution
A washer attachment portion is integrated into the squeegee head, allowing the washer to be attached via a screw or threaded hole, enabling attachment even when the handle head and back plate are joined, and allowing for dual usage modes by switching the washer's position between the front and back sides.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the handle head and back plate are joined to each other, then the squeegee structure is stable and rigid, but the washer cannot be attached to the squeegee head
Solution Approach 1:
The squeegee head is divided into distinct functional zones: the overlapping area where the handle head and back plate are joined, and the non-overlapping side areas where washer attachment portions are provided. This segmentation allows the joined structure to maintain rigidity while creating dedicated spaces for washer attachment that are not interfered with by the handle head-back plate connection.
2Adaptability or versatility
If additional attachment components are added to enable washer attachment, then washer attachment is enabled, but the device complexity increases
Solution Approach 1:
The washer attachment portions are designed with universal screw holes that can accommodate different washer types and configurations. The same attachment structure enables attachment of washers to the squeegee head whether the handle head and back plate are joined or separated, making the attachment mechanism versatile and eliminating the need for multiple specialized attachment components.
3Device complexity
If the washer attachment portion is placed in the overlapping area of handle head and back plate, then the attachment structure is simplified, but the washer cannot be attached when handle head and back plate are joined
Solution Approach 1:
Instead of placing washer attachment portions only in the overlapping area (one-dimensional solution), the invention extends attachment capability to the non-overlapping side areas (adding spatial dimension). This allows washers to be attached laterally to the squeegee head, creating a two-dimensional attachment layout that avoids interference with the handle head-back plate joining while maintaining structural simplicity.

AI summary
This invention enables attachment of a washer to a squeegee head in a state in which the handle head and a back plate are joined to each other. A squeegee includes a handle, a back plate and a channel. The handle includes a handle head and a grip. A channel is clamped between the handle head and the back plate. A part of the squeegee on a front end side relative to the grip, the part excluding the channel, is referred to as a squeegee head. The squeegee includes a washer attachment portion which enables attachment of a washer to the squeegee head in a state in which the back plate is attached to the handle head. The washer attachment portion is disposed in an area of the squeegee head, the area being off an area in which the handle head and the back plate overlap each other.
