Solution Overview

Problem

Traditional door handle mechanisms require complicated and time-consuming adaptations to fit varying door thicknesses, often involving cutting components to size, which is inefficient and labor-intensive.

Innovation Solution

A modular adapter set comprising spindle and post adapters with varying diameters and coupling mechanisms, such as magnets and threads, allows for quick and tool-free adjustment of door handle mechanisms to fit different door thicknesses by removably connecting to existing spindle and post components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional door handle mechanisms are adapted by cutting components to size, then the door handle can fit varying door thicknesses, but the installation process becomes complicated and time-consuming

Engineering Contradiction:

Improveadaptability to varying door thicknessesVSAvoidinstallation time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The extension component is divided into multiple discrete segments of different lengths (e.g., 1/2 inch, 3/4 inch, 1 inch segments). These segmented components can be selectively assembled to match various door thicknesses without requiring cutting or modification, thereby reducing installation time while maintaining adaptability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system transitions from a static, fixed-length extension component to a dynamic, adjustable configuration using multiple removable segments. This allows the extension length to be adapted on-demand to match different door thicknesses, eliminating the need for time-consuming cutting operations.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If traditional door handle mechanisms are adapted by cutting components to size, then the door handle can fit varying door thicknesses, but the adaptation process becomes complicated and labor-intensive

Engineering Contradiction:

Improveadaptability to varying door thicknessesVSAvoidease of adaptation

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A single set of standardized extension segments can be used across different door handle mechanisms and door thicknesses. This universal approach eliminates the need for custom-cut components for each installation, simplifying the adaptation process and reducing labor requirements.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If multiple door handle mechanisms are designed for different door thicknesses, then adaptability is improved, but the number of products needed increases

Engineering Contradiction:

Improveadaptability to varying door thicknessesVSAvoidnumber of products

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

Instead of manufacturing separate extension components for each door thickness, the system segments the extension into standardized modules (1/2 inch, 3/4 inch, 1 inch segments). A single product line with these modular segments can serve multiple door thickness requirements, reducing the total number of distinct products needed.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The extension segments are designed to nest within each other or be stacked in sequence, allowing multiple length configurations to be achieved using a compact set of base components. This nesting approach minimizes the number of separate products required while maintaining versatility across different door thicknesses.

Inventive Principle:

Principle #7Nested doll (Nesting)
