Tile Removal Assembly With Flexible Claw And Rigid Chisel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tile removal devices require high accuracy in swinging to drive a claw beneath tiles, and existing tools lack a balanced design for efficient prying and nail removal.
Innovation Solution
A tile removal device with a thin, flexible claw portion and a thick, rigid chisel portion attached to a handle, allowing the claw to easily fit under tiles without precise swinging and the chisel to pry objects effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the claw portion is made thick to increase strength, then the claw portion becomes rigid and cannot flex to travel between the tile and hard floor surface, but if the claw portion is made thin to enable flexing, then the strength is reduced
Solution Approach 1:
The head is designed with non-uniform thickness distribution: the claw portion is made thin (0.05-0.15 inches) to enable flexing and travel between tile and floor surface, while the chisel portion is made thick (0.25-0.50 inches) to provide rigidity for prying. This local differentiation of structural properties resolves the contradiction between flexibility and strength requirements for different functional zones.
2Strength
If the chisel portion is made thin to reduce weight, then the chisel portion becomes flexible and cannot effectively pry fixed objects, but if the chisel portion is made thick to increase rigidity, then the overall weight of the tool increases
Solution Approach 1:
The chisel portion is concentrated with thickness (0.25-0.50 inches) only where needed for prying fixed objects, while other portions of the head maintain reduced thickness. This localized reinforcement provides the necessary rigidity for the prying function without unnecessarily increasing the overall weight of the tool.
3Ease of operation
If the claw portion is made rigid to increase strength, then high accuracy swinging is required to drive the claw beneath the tile, but if the claw portion is made flexible, then accuracy requirements are reduced
Solution Approach 1:
The claw portion's thickness parameter is specifically optimized to 0.05-0.15 inches, creating a controlled flexibility that allows the claw to bend and absorb impact variations during swinging. This parameter adjustment reduces the accuracy requirement for driving the claw beneath tiles while maintaining sufficient strength through the head's overall structural design and material selection.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates easy and accurate tile removal and nail extraction with reduced effort, enhancing efficiency and ease of use.
Implementation Method 1
The claw portion has a thickness that is sufficiently thin to facilitate the claw portion to flex when the head is swung toward a tile is bonded to a hard floor surface
Implementation Method 2
The chisel portion has a thickness that is sufficiently thick to inhibit the chisel portion from flexing thereby facilitating the chisel portion to pry a fixed object

AI summary
A tile removal assembly includes a tool that has a handle and a head attached to the handle. The head has a claw portion extending laterally away from the handle and a chisel portion extending laterally away from the handle in an opposite direction from the claw portion. The claw portion has a thickness that is sufficiently thin to facilitate the claw portion to flex when the head is swung toward a tile is bonded to a hard floor surface. In this way the claw portion can travel between the tile and the hard floor surface to facilitate a user to drive the claw portion beneath the tile without requiring the user to swing the tool with a high degree of accuracy. The chisel portion has a thickness that is sufficiently thick to inhibit the chisel portion from flexing thereby facilitating the chisel portion to pry a fixed object.
