Adjustable Mortise Template Kit for Varying Door Thicknesses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door mortise templates are not easily adaptable to varying door thicknesses and heights, limiting their versatility in flush mounting hinges and strike plates.
Innovation Solution
A template kit with a adjustable holder and interchangeable templates, featuring cams for thickness adjustment and reversible templates with tape measure tabs for precise placement, allowing for easy configuration with doors of different thicknesses and shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed template is used for routing mortises, then the template can be simple in structure, but it cannot accommodate doors of varying thicknesses and heights
Solution Approach 1:
The template incorporates adjustable components including offsetting legs with feet that can be positioned at different locations, and reversible templates that can be flipped to provide different mortise patterns. This dynamic adjustability allows the same template structure to adapt to doors of varying thicknesses and heights without requiring multiple dedicated templates.
Solution Approach 2:
The template is divided into separate functional components: a holder structure, offsetting legs, feet with mounting apertures, and reversible template plates. This segmentation allows each component to be independently adjusted or reconfigured to match different door specifications while maintaining overall template functionality.
2Adaptability or versatility
If multiple templates are provided for different door thicknesses, then adaptability improves, but the device becomes more complex and harder to manage
Solution Approach 1:
The template holder and offsetting legs serve multiple functions: they provide structural support, enable adjustment to different door thicknesses through repositioning feet, and work with reversible templates to create various mortise patterns. This multi-functionality consolidates what would otherwise require multiple separate templates into a single versatile tool.
Solution Approach 2:
The reversible templates can be flipped to provide different mortise patterns, and the feet can be repositioned along the offsetting legs to accommodate different door thicknesses. This dynamic reconfigurability allows a single template kit to replace multiple fixed templates while maintaining ease of operation through simple mechanical adjustments.
3Adaptability or versatility
If adjustable components are added to make the template adaptable to different door thicknesses, then versatility improves, but the template holder structure becomes more complex
Solution Approach 1:
The template holder is segmented into a main body and separate offsetting legs that can be independently positioned. The feet are further segmented as separate mounting components that can be attached at different locations on the offsetting legs. This segmentation allows for adaptability while keeping each individual component relatively simple in structure.

AI summary
A kit for forming mortises in door edges and door frames for flush-mounting door hinges, strike plates and latch plates is provided. The kit generally includes a template holder and a plurality of templates mountable to the template holder. The templates provide guides for various size hinges, strike plates or latch plates. The template holder includes an adjustment mechanism for easily adapting the template holder from doors having a first thickness to doors having a second thickness. The adjustment mechanisms include a rotatable cam and knob. The kit may optionally include an alignment schedule providing distances for locating the templates relative to a door end or a frame. Further, the templates may include tab engagement slots for engaging a tape measure.
