Solution Overview

Problem

Existing fastening solutions for light grid housings are complex and require multiple parts, making them difficult to attach directly to neighboring components and limiting flexibility in fastening direction.

Innovation Solution

A fastening apparatus with a base part featuring a partly round housing cross-section and an open receiver with a circular section angle of more than 180 degrees, allowing the light grid housing to be securely held without additional tools, using a two-part system consisting of a base part and a clamping part, which can be rotated and adjusted for precise positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing fastening solutions are used, then the light grid housing can be fastened, but the fastening apparatus requires multiple parts and is complex

Engineering Contradiction:
Improvefastening securityVSAvoidnumber of parts
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The receiver integrates multiple functions into a single component: it provides the fastening interface, includes integrated fastening elements (clamps, clips, or latches), and offers adjustment capabilities. This merging of functions reduces the number of separate parts while maintaining secure fastening and adjustability of the light grid housing.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If existing fastening solutions are used, then the light grid housing can be attached, but it is difficult to attach directly to neighboring components

Engineering Contradiction:
Improveattachment securityVSAvoidease of attachment
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The receiver is designed with universal fastening elements (clamps, clips, or latches) that can engage with various types of mounting surfaces and neighboring components. This multi-functionality allows direct attachment to different neighboring components without requiring specialized interfaces, simplifying the attachment process while ensuring secure fastening.

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

3Reliability

If existing fastening solutions are used, then the light grid housing can be fastened, but the fastening direction is limited

Engineering Contradiction:
Improvefastening securityVSAvoidfastening direction flexibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The receiver incorporates adjustable fastening elements (clamps, clips, or latches) that can be positioned and oriented in multiple directions. This dynamic capability allows the fastening direction to be adapted based on the orientation of neighboring components, providing flexibility in installation while maintaining secure attachment.

Inventive Principle:
Principle #15Dynamics
