Problem

Existing methods for installing doors in door frames are either not sturdy enough for repeated use, overly complex, or too expensive, leading to inaccuracies and security issues due to insecure template attachments and complex constructions.

Innovation Solution

A template-based apparatus with turn-lock fasteners and adjustable elements, including lasers for alignment, and interchangeable template bases for guiding tools to form precise mortises and holes, ensuring secure and accurate installation of door hardware.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If prior template systems are used for door installation, then basic functionality is provided, but they are not sturdy enough for repeated use and result in insecure connections leading to inaccuracies

Engineering Contradiction:
Improveconnection securityVSAvoidmortise and hole positioning accuracy
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The template system is divided into a base component and interchangeable insert components, allowing the base to provide structural stability while inserts provide precise positioning features for different door hardware configurations

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The template inserts are pre-configured with precise geometric features and positioning elements that establish accurate mortise and hole locations before the actual cutting operation begins, ensuring consistent positioning across multiple uses

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If prior template systems with adapter plates are used, then versatility is provided, but the attachment provisions are overly complex and do not result in secure connections

Engineering Contradiction:
Improvehardware configuration flexibilityVSAvoidattachment mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A single base template design serves multiple functions by accommodating various insert types for different door hardware configurations (hinges, locks, viewers), eliminating the need for multiple complex adapter plates while maintaining versatility

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The base template and positioning features are merged into a unified structure where the base provides attachment security and the inserts provide hardware-specific guidance, simplifying the overall system compared to separate adapter plate mechanisms

Inventive Principle:
Principle #5Merging (Combining)

3Manufacturing precision

If complex prior devices are used for installing hinges and lock-sets, then acceptable accuracy is provided, but they are too complex in construction and undesirably expensive

Engineering Contradiction:
Improvehardware installation accuracyVSAvoidapparatus construction complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The complex device is segmented into a simple reusable base and disposable or interchangeable inserts, where the base contains the complex positioning geometry that can be used repeatedly, reducing overall system complexity and cost

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Standardized insert designs replicate proven positioning geometries for common door hardware configurations, allowing accurate replication of professional-grade installation templates at reduced complexity and cost

Inventive Principle:
Principle #26Copying
