Solution Overview

Problem

Existing milling machines, particularly swivel spindle milling machines, require significant space and are not feasible for do-it-yourself workshops due to space constraints, while stationary milling machines offer advanced setting options that hobbyists cannot afford or install.

Innovation Solution

An interchangeable milling adapter that allows a milling machine to be connected to a workbench, featuring an angular adjustment and a receptacle for easy attachment and positioning, enabling the same setting options as professional machines without occupying excessive space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a stationary swivel spindle milling machine is used, then advanced setting options and milling functionality are provided, but space requirements become excessive for hobbyist workshops

Engineering Contradiction:
Improvemilling functionalityVSAvoidspace requirement
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The milling machine is divided into two independent parts: a stationary work table and a movable milling unit with angular adjustment. This segmentation allows the milling functionality to be detached from the work table, enabling space-efficient storage when the milling unit is not in use, while still providing full milling capabilities when needed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The milling unit is designed with angular adjustment capability, allowing it to dynamically change its orientation relative to the work table. This dynamic positioning enables the same versatility as stationary swivel spindle machines while maintaining a compact footprint when the milling unit is retracted or stored.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If a stationary milling machine with multiple setting options is purchased, then professional milling capabilities are achieved, but acquisition costs and space requirements become prohibitive for hobbyists

Engineering Contradiction:
Improvesetting optionsVSAvoidacquisition cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The work table is designed with universal compatibility to accept different milling units through the angular adjustment mechanism. This multi-functionality allows a single base unit to provide various milling capabilities through different tool configurations and angular settings, reducing the need for multiple specialized machines and thereby lowering acquisition costs.

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

Solution Approach 2:

The angular adjustment mechanism provides dynamic setting options that replicate the functionality of expensive stationary machines. By allowing the milling unit to be positioned at various angles, the system achieves professional-grade versatility without requiring a fully stationary, hard-to-move machine configuration.

Inventive Principle:
Principle #15Dynamics

3Area of stationary object

If an interchangeable milling adapter with angular adjustment is used, then space efficiency and affordability are improved, but the complexity of the connection device increases

Engineering Contradiction:
Improvespace requirementVSAvoidadapter complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The angular adjustment mechanism serves as an intermediary component between the work table and the milling unit. This mediator provides the necessary connection and positioning functionality without requiring complex integration into either the table or the milling unit itself, thereby managing complexity while achieving angular adjustment capability.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The adapter is designed as a separate, modular component that can be independently adjusted and positioned. This segmentation of the adjustment function from the main structural components simplifies the overall design by allowing each part to be optimized independently, reducing the complexity burden on any single component.

Inventive Principle:
Principle #1Segmentation
