Solution Overview

Problem

Existing connectors for door or window frames to thresholds are inflexible and require costly, time-consuming adaptations to match varying frame and attachment profile geometries, necessitating specialized tools and increasing logistics complexity.

Innovation Solution

A modular connector with adjustable support elements that can be configured in multiple positions to match different frame and attachment profile shapes, using asymmetrical trapezoidal support surfaces and interlocking projections/recesses for secure alignment, allowing for flexible adaptation without additional tools or effort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If known connectors are used with predetermined outer contour shapes, then manufacturing is simplified, but adaptability to different frame profile geometries is reduced

Engineering Contradiction:
Improveconnector manufacturing simplicityVSAvoidadaptability to different frame profiles
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The connector is divided into multiple support elements (first support element, second support element, third support element) that can be independently positioned and configured. Each support element can be adjusted to different positions to accommodate various frame profile geometries, while the modular structure maintains manufacturing simplicity through standardized components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connector transitions from a static, predetermined shape to a dynamic, adjustable configuration. The support elements can be positioned at different locations and orientations to match different frame profiles, allowing the connector to adapt its outer contour dynamically during assembly without requiring custom manufacturing for each profile type.

Inventive Principle:
Principle #15Dynamics

2Shape

If connectors are adapted to match frame profile cross-sections through milling, then shape correspondence is improved, but manufacturing time and cost increase

Engineering Contradiction:
Improveouter contour correspondenceVSAvoidadaptation time
Core Design Contradiction:
ShapeVSLoss of time

Solution Approach 1:

The support elements are pre-configured with specific geometries and connection features that allow them to be directly positioned and attached to match frame profiles without requiring on-site milling or adaptation. The preliminary design of the support elements incorporates various configuration possibilities, enabling direct installation that preserves both shape correspondence and time efficiency.

Inventive Principle:
Principle #10Preliminary action

3Manufacturing precision

If specialized processing tools are used for connector adaptation, then shape precision is improved, but logistics expenditure increases

Engineering Contradiction:
Improveshape adaptation precisionVSAvoidlogistics complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The connector design enables self-adjustment through the configurable support elements that can be positioned and fixed using standard assembly methods. The system serves itself by providing multiple pre-designed support element configurations that can be selected and assembled to match different frame profiles without requiring external specialized tools or complex logistics for tool management.

Inventive Principle:
Principle #25Self-service

4Productivity

If connector shape is fixed by manufacturing process, then production efficiency is improved, but flexibility in assembly is reduced

Engineering Contradiction:
Improveconnector production efficiencyVSAvoidassembly flexibility
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

By segmenting the connector into multiple independently configurable support elements, the design maintains high production efficiency through standardized manufacturing of each element while providing assembly flexibility through different positioning and configuration options of the segments during installation.

Inventive Principle:
Principle #1Segmentation
