Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing extrusion profiles for hobby robotics lack customizable center and peripheral apertures, drill guides, and beveled edges that can accommodate standard components and reduce friction and backlash in linear motion systems.

Innovation Solution

The extrusion profile features a center aperture with vertical and horizontal drill guides, peripheral apertures sized for standard threads, and beveled edges for compatibility with V-wheels and bearings, allowing for customizable integration with standard components and reduced friction in linear actuator assemblies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If standard extrusion profiles are used, then manufacturing simplicity is maintained, but customization capability for specific components is limited

Engineering Contradiction:

Improvecustomization capabilityVSAvoidextrusion profile complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The extrusion profile is segmented into multiple functional zones: center aperture region with drill guides, peripheral aperture regions, and beveled edge regions. Each segment serves a specific customization function while maintaining overall profile integration, allowing modular adaptation without complete redesign

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The extrusion profile incorporates multiple functions within a single structure: structural support, routing (center aperture), mounting (peripheral apertures with drill guides), and reduced friction interfaces (beveled edges). This multi-functionality enables one profile design to serve multiple customization needs

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Manufacturing precision

If drill guides are added to the extrusion profile, then manufacturing precision for aperture alignment is improved, but manufacturing complexity increases

Engineering Contradiction:

Improveaperture alignment precisionVSAvoidextrusion manufacturing ease

Core Design Contradiction:

Manufacturing precisionVSEase of manufacture

Solution Approach 1:

Drill guides are pre-formed as integral features of the extrusion profile during the extrusion process itself, rather than being added as separate components afterward. This preliminary action ensures precise aperture alignment is built-in from the start, eliminating the need for subsequent complex alignment operations

Inventive Principle:

Principle #10Preliminary action

3Reliability

If beveled edges are incorporated, then friction in linear motion systems is reduced, but manufacturing complexity increases

Engineering Contradiction:

Improvelinear motion performanceVSAvoidprofile geometric complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The beveled edges modify the geometric parameters of the extrusion profile by introducing angled surfaces at specific locations. This parameter change creates optimized contact surfaces that reduce friction and backlash in linear motion applications while maintaining compatibility with standard V-wheels and bearings

Inventive Principle:

Principle #35Parameter changes
