Solution Overview

Problem

Current methods for attaching roller hinges to door and window profiles require individual alignment and drilling of each profile, leading to inaccuracies and increased processing time due to the need for multiple applications of drilling templates, which can result in misaligned hole patterns and inefficient assembly.

Innovation Solution

A tool with a U-shaped clamping device and modular compensating elements allows for simultaneous alignment and fixation of frame and sash profiles, using a single drilling template to ensure accurate and concurrent drilling of both profiles, reducing processing time by two-thirds.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If individual alignment and drilling of each profile is performed using separate drilling templates, then flexibility in processing different profiles is maintained, but manufacturing precision deteriorates due to cumulative alignment errors and time consumption increases due to multiple template applications

Engineering Contradiction:

Improveflexibility in processing different profilesVSAvoidalignment accuracy of hole patterns

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent combines multiple drilling templates into a single integrated tool that simultaneously positions and drills both the frame profile and sash profile. This unified drilling tool eliminates the need for separate template applications and ensures precise alignment of hole patterns across both profiles by maintaining fixed relative positioning between the frame and sash during the drilling operation.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The tool pre-establishes the correct alignment and spacing between the frame profile and sash profile using adjustable positioning elements and clamping mechanisms before the drilling operation begins. This preliminary positioning ensures that when drilling occurs, the hole patterns are automatically aligned with the required precision without needing separate alignment steps for each profile.

Inventive Principle:

Principle #10Preliminary action

2Ease of manufacture

If individual alignment and drilling of each profile is performed using separate drilling templates, then processing can be done with simple equipment, but productivity deteriorates due to the need to apply templates multiple times

Engineering Contradiction:

Improvesimplicity of equipmentVSAvoidprocessing time

Core Design Contradiction:

Ease of manufactureVSProductivity

Solution Approach 1:

The patent merges the functionality of multiple separate drilling templates into a single integrated drilling tool that can position and drill both profiles simultaneously. This combination reduces the number of template applications from multiple separate operations to a single unified operation, significantly reducing processing time while maintaining equipment simplicity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The tool enables continuous drilling operation on both profiles without interruption by holding both profiles in fixed positions and drilling through both simultaneously. This eliminates the downtime associated with removing and repositioning separate templates between profiles, maintaining continuous productive action throughout the drilling process.

Inventive Principle:

Principle #20Continuity of useful action

3Stability of the object's composition

If drilling templates are clamped with screw clamps to ensure positioning, then fixation stability is improved, but manufacturing precision deteriorates due to template shifting during clamping

Engineering Contradiction:

Improvefixation stability of templateVSAvoidalignment accuracy of drilling pattern

Core Design Contradiction:

Stability of the object's compositionVSManufacturing precision

Solution Approach 1:

The tool establishes the correct positioning and alignment of both profiles using adjustable positioning elements and clamping mechanisms before the drilling operation begins. This preliminary positioning ensures that when drilling occurs, the hole patterns are automatically aligned with the required precision without needing separate alignment steps for each profile.
