Drill Guide With Removable Clamp Retainer For Irregular Angles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drill guides in woodworking lack flexibility and precision in positioning at irregular angles, and they often require specific clamps that limit compatibility with different fixtures.
Innovation Solution
A drill guide apparatus with individually moveable sliders on tracks and a removable clamp retainer allows for precise positioning at non-perpendicular angles and accommodates various clamps through a flexible clamp adapter system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed clamp retainer is integrated into the drill guide body, then the clamp is securely held in position, but the drill guide lacks flexibility to accommodate different clamp types and positioning requirements
Solution Approach 1:
The clamp retainer is separated from the drill guide body as a distinct, removable component. This segmentation allows the retainer to be detached when compatibility with a particular clamp type is required, while the drill guide body remains intact. The retainer can be selectively attached or removed based on the specific clamp being used, providing versatility without compromising the security of clamp retention when the retainer is properly installed.
Solution Approach 2:
The clamp retainer system transitions from a static, fixed integration to a dynamic, removable configuration. The retainer can be attached to the drill guide body when needed for secure clamp holding, and removed when flexibility to use different clamp types is required. This dynamic adaptability resolves the contradiction between security and versatility.
2Adaptability or versatility
If drill guides are fixed at perpendicular angles only, then manufacturing and alignment are simplified, but positioning flexibility at irregular angles is lost
Solution Approach 1:
The drill guide apparatus transitions from a fixed, static configuration to a dynamic, adjustable system. The guide can be repositioned along the track to accommodate different workpiece thicknesses and positioning requirements, enabling accurate alignment at various angles including irregular angles while maintaining manufacturing precision through the constrained motion path of the track.
Solution Approach 2:
The track acts as an intermediary element between the drill guide body and the workpiece. It provides a guided path that allows the drill guide to be positioned accurately at various locations and angles while maintaining alignment precision. The track mediates between the need for manufacturing simplicity and the requirement for positioning flexibility.
3Adaptability or versatility
If a removable clamp retainer is used, then flexibility to accommodate different clamp types is achieved, but the complexity of the drill guide assembly increases
Solution Approach 1:
By segmenting the clamp retainer as a separate component, the system gains versatility to accommodate different clamp types while keeping the added complexity isolated to a single removable piece rather than integrating complexity throughout the entire drill guide assembly. The modular design allows the retainer to be attached or removed as needed.
4Measurement precision
If individually moveable sliders are added to the drill guide, then positioning precision at non-perpendicular angles is improved, but the device complexity increases
Solution Approach 1:
The sliders act as intermediary elements that translate simple linear motion along the track into precise positioning of the drill guide at various angles and locations. Rather than requiring complex direct control mechanisms, the sliders mediate between the simple track structure and the precise positioning requirement, improving measurement precision while adding relatively simple mechanical components.

AI summary
A drill guide apparatus includes a body providing a workpiece clamping surface. The body includes one or more drill guides, wherein the one or more drill guides pass through the workpiece clamping surface at an acute angle, a first track, and a second track. The drill guide apparatus further comprises a first slider mounted on the first track, and a second slider mounted on the second track. The first slider includes a first extrusion that extends beyond the workpiece clamping surface and is slideable along the first track to adjust the position of the first extrusion relative to the workpiece clamping surface. The second slider includes a second extrusion that extends beyond the workpiece clamping surface and is slideable along the second track to adjust the position of the second extrusion relative to the workpiece clamping surface. The drill guide may also include a removeable clamp retainer.
