Solution Overview

Problem

Existing three-dimensional object production devices are time-consuming to align during installation or relocation due to their multi-point support systems, which require adjustments at multiple points for stable alignment.

Innovation Solution

A three-point support system with height-adjustable feet allows for quick and reliable alignment by changing the height at three points, preventing wobbling and tilting, and featuring a tripod construction with rollers and spirit levels for precise horizontal alignment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a multi-point support system is used, then stability of the device is improved, but alignment time and complexity increase

Engineering Contradiction:
Improvedevice stabilityVSAvoidalignment time
Core Design Contradiction:
Stability of the object's compositionVSLoss of time

Solution Approach 1:

The support system is segmented into exactly three support points instead of multiple support points, simplifying the alignment process while maintaining stability. The three-point support structure allows alignment to be achieved by adjusting only three points rather than multiple points, directly reducing alignment time and complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support feet are made height-adjustable to provide local adaptability at each support point. This allows precise control of the device's alignment by independently adjusting the height of each of the three support feet, enabling quick and reliable alignment without requiring adjustment at multiple locations.

Inventive Principle:
Principle #3Local quality

2Stability of the object's composition

If a multi-point support system is used, then stability of the device is improved, but device complexity increases

Engineering Contradiction:
Improvedevice stabilityVSAvoidsupport system complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The support system is simplified to exactly three support points arranged in a tripod configuration, eliminating the complexity of multi-point support systems. This segmented approach with only three points reduces the number of components and adjustment mechanisms while maintaining stability through the inherent rigidity of the tripod structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The height-adjustable feet combine the functions of support and alignment adjustment into a single integrated component. Each support foot simultaneously provides structural support and enables alignment adjustment through height modification, reducing the need for separate alignment mechanisms and simplifying the overall device structure.

Inventive Principle:
Principle #5Merging (Combining)

3Measurement precision

If height-adjustable support feet are used, then alignment precision is improved, but ease of operation is reduced

Engineering Contradiction:
Improvealignment precisionVSAvoidalignment operation
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The support feet are equipped with height-adjustment mechanisms that provide precise local control at each of the three support points. This localized adjustment capability enables fine-tuning of the device's alignment by modifying the height of individual feet, achieving high alignment precision through simple, focused adjustments rather than complex global adjustments.

Inventive Principle:
Principle #3Local quality
