Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a quick-release fastener with spring element and locking lugs is used, then assembly is simplified and operation ease is improved, but device complexity increases due to larger number of individual parts

Engineering Contradiction:
Improveassembly simplicityVSAvoidnumber of individual parts
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines multiple fastening functions into a single integrated holding device. The holding element with spring element, locking lugs, and control element are merged into one unit that attaches to the mounting rail, eliminating the need for separate fastening components and reducing overall device complexity while maintaining ease of assembly.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The holding device is designed as a multi-functional component that simultaneously provides attachment to the mounting rail, secure holding of the component, and controlled release mechanisms. This universal design consolidates multiple functions into a single device, reducing the number of individual parts needed.

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

2Reliability

If rotary bolts are used to fasten components to mounting rails, then secure connection is achieved, but operation ease deteriorates due to requirement of simultaneous two-handed operation

Engineering Contradiction:
Improveconnection securityVSAvoidhandling difficulty
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The holding element is designed to automatically secure the component to the mounting rail upon attachment. The spring element and locking lugs engage automatically without requiring manual intervention to tighten or secure the connection, eliminating the need for simultaneous two-handed operation while maintaining secure connection.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The holding element is pre-configured with spring elements and locking lugs that are ready to engage with the mounting rail immediately upon attachment. The secure connection is prepared in advance through the pre-loaded spring mechanism, eliminating the need for subsequent tightening operations.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If holding element is made with spring element and locking lugs, then automatic locking is achieved improving operation ease, but device complexity increases due to additional components

Engineering Contradiction:
Improveautomatic lockingVSAvoidcomponent count
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The spring element, locking lugs, and control element are merged into a single integrated holding element that attaches directly to the mounting rail. This consolidation achieves automatic locking functionality without requiring separate spring components, locking mechanisms, or control elements as individual parts.

Inventive Principle:
Principle #5Merging (Combining)

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

Enables easy and secure mounting of components like lamp inserts and reflectors on mounting rails with reduced complexity and cost, allowing for adjustable locking states and preventing unintentional release.

Implementation Method 1

The holding device is pressed onto a mounting rail profile and rotates by a predetermined angular range while simultaneously generating a spring preload and snaps back using the spring preload

Methodology Applied
Scientific EffectSpring: Spring

Implementation Method 2

The holding element is acted upon by a spring or is made from an elastic material, in particular metal or a metal alloy

Methodology Applied
Scientific EffectElasticity: Elasticity
