Solution Overview

Problem

Protective covers for machine elements often obstruct natural lighting, necessitating additional lighting in work areas, especially when used in applications where visibility is crucial, such as machine tools, due to the shielding effect of support frames and bellows sections, even when made of translucent materials.

Innovation Solution

The protective cover features transparent and/or translucent bellows sections and support frames, allowing partial light penetration, especially at oblique angles, and uses flexible, partially or fully transparent materials like plastic films or extruded sections with different materials for optimal light transmission and flexibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If protective covers with support frames and bellows sections are used to cover machine elements, then mechanical protection is provided, but lighting conditions in the work area deteriorate due to shielding of natural and hall lighting

Engineering Contradiction:
Improvemechanical protectionVSAvoidlighting conditions
Core Design Contradiction:
ReliabilityVSIllumination intensity

Solution Approach 1:

The bellows sections are made transparent or translucent in the light-transmitting areas while maintaining structural integrity, allowing light to pass through specific regions. The support frames are designed with transparent sections where light transmission is needed, while other parts can remain opaque for structural support. This local differentiation of material properties resolves the contradiction between protection and lighting.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The protective cover combines transparent or translucent materials (such as transparent plastics or glass) with opaque structural elements. The bellows sections use transparent materials to allow light transmission, while the support frames combine transparent sections for light passage with opaque sections for mechanical strength. This composite approach enables simultaneous achievement of mechanical protection and improved lighting conditions.

Inventive Principle:
Principle #40Composite materials

2Illumination intensity

If side walls are designed to be sufficiently high to allow top covers to be dispensed with, then lighting conditions improve, but device complexity and space requirements increase

Engineering Contradiction:
Improvelighting conditionsVSAvoidstructural complexity
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The protective cover with transparent bellows sections and support frames serves multiple functions: it provides mechanical protection for machine elements, maintains safety enclosures, and simultaneously allows light transmission to improve work area illumination. This multi-functionality eliminates the need for alternative high-side-wall designs, reducing overall device complexity while achieving both protection and lighting goals.

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

3Illumination intensity

If fluorescent tubes are attached behind the protective cover, then lighting conditions improve, but additional energy consumption and device complexity increase

Engineering Contradiction:
Improvelighting conditionsVSAvoidenergy consumption
Core Design Contradiction:
Illumination intensityVSUse of energy by moving object

Solution Approach 1:

The bellows sections and support frames are made transparent or translucent, changing the optical properties of the protective cover from opaque to light-transmitting. This material property change allows natural and hall lighting to pass through the protective cover into the work area, eliminating or reducing the need for additional fluorescent lighting and associated energy consumption.

Inventive Principle:
Principle #32Color changes

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case
