Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing planing devices, such as handheld manual planers and CNC machines, face challenges in precision, user effort, and cost-effectiveness, making them impractical for home or small shop use.
Innovation Solution
A compact, lightweight, and easy-to-set-up motorized planing apparatus that uses a carriage with rollers to move along a support, a bracket with actuators to move along the X and Y axes, and a controller to manage the cutting tool's movement and adjust for tool dulling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If handheld manual planing devices are used, then the device is simple and portable, but the cutting precision and consistency deteriorate
Solution Approach 1:
The device is segmented into distinct functional modules: a carriage system with independent X and Y axis actuators, a replaceable cutting tool holder, and a controller. This modular segmentation allows each component to be optimized independently, achieving CNC-level precision through coordinated control while keeping individual components simple and manageable.
Solution Approach 2:
The device incorporates dynamic positioning systems with actuators that can adjust the cutting tool's position in real-time along both X and Y axes. This dynamic capability enables precise control of cutting depth and position, transforming a static simple device into a dynamically adjustable precision tool.
2Manufacturing precision
If CNC machines are used, then the cutting precision and automation are improved, but the device complexity and cost increase
Solution Approach 1:
The invention extracts only the essential precision-control elements from full CNC machines: a carriage with two-axis actuation and a controller. It deliberately omits complex features like multi-tool changers, automated material handling, and sophisticated safety systems, creating a simplified precision device suitable for home workshops.
Solution Approach 2:
The device uses affordable, easily replaceable components such as standard actuators and a simple controller rather than expensive industrial-grade systems. The cutting tools are designed to be easily replaceable, allowing users to maintain precision without investing in costly proprietary tooling systems.
3Extent of automation
If CNC machines are used, then the automation level is improved, but the ease of operation and setup deteriorate
Solution Approach 1:
The device is pre-configured with a simple controller and basic automation routines that handle the complex coordination of multiple actuators. Users only need to load the workpiece and select basic operations, while the pre-programmed control system automatically manages the precise multi-axis coordination, eliminating the need for users to learn complex programming.
4Device complexity
If handheld manual planing devices are used, then the device is portable and simple, but user fatigue increases due to manual effort
Solution Approach 1:
The device incorporates self-propelling actuators that automatically move the carriage and cutting tool along the workpiece. The system serves itself by automatically positioning the tool, maintaining cutting depth, and returning to starting positions, eliminating the need for continuous manual guidance and reducing user fatigue.

AI summary
An apparatus includes a carriage, and a first member and a second member coupled to the carriage. The first and second member each have rollers positioned to freely roll along a support and move the carriage. A first set of rollers are positioned in a horizontal plane and a second set of rollers are positioned in a vertical plane. A bracket is coupled to the carriage and configured to hold a cutting tool. The bracket is configured to move along an X-axis and a Y-axis. A plurality of actuators is configured to move the bracket along the X-axis and the Y-axis. Each sensor of a plurality of sensors is configured to generate signals comprising the position of the apparatus. A controller is configured to receive the signals from the sensors and data. The controller executes instructions for controlling movement of the bracket based on the signals and the data.
