Concealed Hinge Jig With Angled Aperture for Precise Hole Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Concealed hinges in cabinet doors and frames often require precise alignment and drilling of holes, which can be challenging due to the need for accurate positioning and angled drilling, especially when using traditional methods that lack efficient alignment and chip evacuation mechanisms.
Innovation Solution
A jig with a main body, central drill bit guide, and alignment cams that allows for angled drilling and adjustable positioning, featuring a non-perpendicular drilling aperture and removable drill bit guides, along with a cabinet hole template for precise hole placement, facilitating accurate alignment and hole formation without the need for tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional drilling methods are used for concealed hinges, then the drilling process is simpler, but alignment accuracy and hole positioning precision deteriorate
Solution Approach 1:
The patent introduces a jig as an intermediary device between the drill bit and the cabinet door. The jig includes a body with a drilling aperture and a central drill bit guide that positions the drill bit at the correct angle and location. This intermediary device ensures precise alignment and hole positioning without requiring complex measurement and calculation procedures during the actual drilling operation.
Solution Approach 2:
The jig is configured with pre-determined geometric features including a drilling aperture with a specific angled sidewall and a central drill bit guide positioned at precise locations. These preliminary arrangements of drilling parameters and guide positions eliminate the need for complex alignment procedures during operation, as everything is pre-configured for accurate hole formation.
2Productivity
If perpendicular drilling aperture is used, then the drilling device structure is simpler, but chip evacuation efficiency deteriorates
Solution Approach 1:
The patent changes the geometric parameter of the drilling aperture by introducing an angled sidewall instead of a perpendicular one. The sidewall extends at a non-perpendicular angle relative to the top and bottom surfaces, creating a tapered configuration that is larger at the top surface than at the bottom surface. This parameter change improves chip evacuation efficiency by providing a more effective chip flow path while the overall device structure remains relatively simple.
3Adaptability or versatility
If fixed drill bit guide position is used, then the device structure is simpler, but adaptability to different hinge positions deteriorates
Solution Approach 1:
The patent makes the drill bit guide position dynamic rather than fixed. The central drill bit guide is removably attached to the main body, allowing it to be repositioned or removed as needed. This dynamic configuration enables the device to adapt to different hinge positions and drilling requirements while maintaining a relatively simple overall structure that can be easily modified.
