Solution Overview

Problem

Existing methods face difficulties in attaching profile elements to the edge areas of curved or irregularly shaped installation openings in walls or ceilings to achieve a uniform and attractive external appearance, especially when elongated lights are installed, as it is challenging to maintain consistent spacing along the longitudinal extension.

Innovation Solution

An aid with a fixing element featuring L-shaped profile elements and clamping elements with specific contact surfaces allows for precise positioning and secure fastening of profile elements to opposite edge regions, using a clamping mechanism that includes a spacer for gap formation and screw connections for easy handling and secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If profile elements are attached to curved or irregularly shaped wall or ceiling areas to create elongated luminaires, then the aesthetic appearance and design flexibility are improved, but the manufacturing precision and consistency of spacing between profile elements deteriorate

Engineering Contradiction:
Improveadaptability to curved or irregularly shaped surfacesVSAvoidspacing consistency between profile elements
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent introduces a spacing template as an intermediary tool between the installer and the profile elements. This template physically enforces consistent spacing by providing fixed-distance contact surfaces that guide the placement of profile elements along curved or irregular surfaces, thereby maintaining manufacturing precision while adapting to complex geometries

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The spacing template is designed with adjustable parameters including variable spacing distances and adaptable contact surface configurations. This allows the same tool to maintain precise spacing across different curvature radii and surface geometries, resolving the contradiction between adaptability and precision by enabling parameter adjustment to match specific installation requirements

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If a spacing template is used to maintain consistent distance between profile elements, then the manufacturing precision is improved, but the device complexity increases

Engineering Contradiction:
Improvespacing consistencyVSAvoidtemplate structure complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The spacing template is segmented into modular components including separate contact surfaces, spacing elements, and attachment mechanisms. This segmentation allows the complex function of maintaining precise spacing on curved surfaces to be achieved through simple, independent parts that can be easily manufactured, assembled, and adjusted without requiring a monolithic complex structure

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If L-shaped profile elements are used with contact surfaces for positioning, then the ease of operation is improved, but the device complexity increases

Engineering Contradiction:
Improvepositioning simplicityVSAvoidfixing element structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The L-shaped profile elements incorporate integrated contact surfaces that automatically engage with corresponding surfaces on the spacing template. This self-aligning mechanism eliminates the need for complex adjustment tools or procedures, as the geometry itself guides correct positioning, thereby improving ease of operation without requiring proportionally complex fixing elements

Inventive Principle:
Principle #25Self-service
