Sliding Notched Trowel for Adjustable Tile Adhesive Spreading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional notched trowels require multiple tools for different notch sizes and pose challenges for left-handed users due to handle placement.
Innovation Solution
An adjustable notched trowel with a bottom plate connected to a top plate via connectors, allowing the bottom plate to slide side-to-side, enabling selective extension and retraction of protrusions and notches, and customizable orientations for varying tile sizes and user handedness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional notched trowels with fixed handle placement are used, then the tool structure is simple, but left-handed users face operational challenges
Solution Approach 1:
The handle is made movable relative to the top plate through a sliding mechanism with slots and connectors, allowing users to adjust handle position and orientation according to their handedness preference, transforming a static structure into a dynamic, adaptable one
Solution Approach 2:
The adjustable handle mechanism enables the same trowel to serve both right-handed and left-handed users effectively, making the tool universal across different user types without requiring multiple specialized versions
2Adaptability or versatility
If multiple fixed-notch trowels are used for different tile sizes, then each trowel is optimized for specific applications, but the quantity of tools required increases
Solution Approach 1:
The bottom plate features movable notches that can be adjusted to different positions along elongated slots, allowing a single trowel to create multiple notch sizes and patterns, replacing the need for multiple fixed-notch trowels
Solution Approach 2:
The adjustable notch mechanism enables one trowel to perform the functions of multiple trowels with different fixed notch configurations, making it suitable for various tile sizes and bonding material applications
3Adaptability or versatility
If multiple trowels are used for different notch sizes, then each trowel provides specialized functionality, but device complexity and selection difficulty increase
Solution Approach 1:
The bottom plate is divided into separate functional elements including movable notches, protrusions, and connectors that can be independently positioned, allowing flexible configuration of notch sizes and patterns from a single unified structure
Solution Approach 2:
The notches and protrusions are designed to be movable along slots rather than fixed, enabling dynamic reconfiguration of the tool's geometry to match different application requirements without changing tools

AI summary
A trowel device includes a bottom plate that is connected to a top plate by a plurality of connectors. The bottom plate includes a generally rectangular-shaped member having a pair of threaded vertical posts, a first plurality of protrusions and notches along a first side, and a second plurality of protrusions and notches along the second side. The top plate includes a handle and a pair of elongated slots for receiving the pair of threaded posts. The bottom plate is secured beneath the top plate by connectors and slides sideways to selectively extend and retract the protrusions and notches from either side of the top plate. A plurality of measurement markers are provided for allowing a user to select exact amounts at which the protrusions and notches are extended outward from either side of the top plate.
