Image-Registered Jig for Precise Multi-Task Workpiece Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing jigs require manual reconfiguration for different tasks, leading to increased costs and inefficiency, as they are typically designed for specific sets of tasks and lack the ability to detect and adjust tools automatically based on the jig being used.
Innovation Solution
A jig equipped with an image-based positioning system that uses features on the jig to determine its location and align with workpieces, allowing for multiple tasks to be performed with minimal manual adjustment, and automatically adjusts tool settings based on detected jig properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a jig is designed for specific tasks, then manufacturing precision is improved, but adaptability deteriorates
Solution Approach 1:
The jig incorporates multiple sets of alignment features and clamping mechanisms that can be configured for different tasks. The base plate includes various mounting holes and adjustable components that allow the same jig to perform multiple functions such as drilling, routing, and cutting across different workpiece types and sizes.
Solution Approach 2:
The jig features adjustable and reconfigurable components including movable fences, adjustable clamps, and repositionable alignment references. These dynamic elements allow the jig to adapt its configuration between tasks while maintaining positioning precision through controlled adjustment mechanisms.
2Device complexity
If manual reconfiguration is required for different tasks, then device complexity is reduced, but productivity deteriorates
Solution Approach 1:
The jig includes pre-configured sets of alignment features and reference markers that are prepared in advance for different task types. Quick-release mechanisms and pre-positioned components allow operators to switch between task configurations without extensive manual adjustment, maintaining relatively simple device structure while improving task switching speed.
3Manufacturing precision
If multiple jigs are purchased for different tasks, then manufacturing precision is maintained, but cost increases
Solution Approach 1:
The jig consolidates multiple task-specific functions into a single device through modular components and reconfigurable features. Different sets of alignment references, clamping points, and guide features can be activated depending on the task, replacing the need for multiple separate jigs while maintaining the precision required for each specific operation.
4Device complexity
If tool settings are adjusted manually for each jig, then device complexity is reduced, but loss of time increases
Solution Approach 1:
The system incorporates sensors and detection mechanisms that automatically identify which jig is being used and communicate this information to the tool control system. This feedback loop enables automatic adjustment of tool settings based on the detected jig configuration, reducing manual setup time while maintaining a relatively simple overall system structure through standardized communication protocols.

AI summary
A jig that allows a user to register a digital design to features on the jig such that a tool with image-based positioning capability, based on the features, can accurately perform a task on a workpiece based on the digital design. The jig may include elements to allow a user to accurately align the jig relative to features, such as corners or edges, of the workpiece. When working with workpieces having a similar geometry, the jig may be moved from one workpiece to the next to allow the user to perform different tasks, using different digital designs, without needing to reconfigure the jig or perform additional set-up on each new workpiece.
