Innovation Solution
A powered tile breaker with an adjustable frame, including a handlebar, foldable shaft, and wheels, featuring an angularly adjustable chiseling assembly powered by a main electric motor and a secondary actuator motor, allowing continuous angle adjustment between 0 and 60 degrees, along with a knee push member for stability and a 'Y' shaped extension for tile clearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the chiseling assembly is made fixed at specific angles, then the device structure is simple and reliable, but the adaptability to different user needs and tile types is limited
Solution Approach 1:
The chiseling assembly is made dynamically adjustable through an electric actuator that enables continuous angle adjustment between 0 and 60 degrees. This allows the system to adapt to different operational requirements and user preferences while maintaining a relatively simple overall structure through automated control.
Solution Approach 2:
The angle of the chiseling assembly is changed as a variable parameter during operation rather than being fixed at manufacturing. The electric actuator modifies the angular parameter in real-time, allowing the same device to perform optimally across different tile types and user configurations without structural complexity.
2Ease of operation
If the shaft is made foldable with hinge and lock means, then the portability and ease of transportation are improved, but the structural complexity and potential reliability issues increase
Solution Approach 1:
The shaft is divided into segments connected by hinges, allowing it to be folded into a compact configuration for transportation. The hinge connections are equipped with lock means that secure the segments in place during operation, providing both portability and structural integrity without requiring complete redesign of the shaft assembly.
3Ease of operation
If multiple adjustment mechanisms are added for ergonomic positioning, then the ease of operation for different users is improved, but the device complexity and number of components increase
Solution Approach 1:
The electric actuator serving the chiseling assembly angle adjustment is integrated with the shaft angle adjustment mechanism. This multi-functional component performs dual purposes: adjusting the chisel angle for different tile types and adjusting the shaft angle for different user heights and preferences, thereby reducing the total number of separate adjustment mechanisms needed.
4Reliability
If the chisel assembly is made heavily constructed for durability, then the strength and reliability are improved, but the weight increases reducing portability
Solution Approach 1:
The chiseling assembly utilizes composite construction combining high-strength materials with optimized structural design. This allows the assembly to maintain durability and reliability for demanding tile breaking applications while keeping the weight manageable for portable operation by users.

AI summary
A powered tile breaker has an adjustable frame and the frame is further comprised of a handlebar member, a foldable shaft, a base member, and wheels. The base member holds a chiseling assembly which comprises a main electric motor located inside a motor casing. The motor powers a chisel member. The chiseling assembly is angularly adjustable by way of an actuator member which consists in a secondary electric motor driving a piston. The piston has one end rotationally connected to the base member, and the actuator member is rotationally connected to a lever member which extends from the chiseling assembly and which connects at a pivot point.
