A covering device with multiple latching elements of varying designs that can engage with different wall thicknesses, featuring elastically resilient components and block-shaped projections to securely attach to various wall elements without additional manufacturing effort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a covering device is designed to match a specific wall thickness, then it provides secure attachment and complete closure, but it cannot be used with wall elements of different thicknesses

Engineering Contradiction:
Improveadaptability to different wall thicknessesVSAvoidnumber of covering device variants
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The covering device is designed with multiple latching elements having different engagement geometries (different angles and positions) so that a single covering device variant can attach to wall elements of various thicknesses. Each latching element is configured to engage with the opening edge at different depths, enabling universal compatibility across different wall thickness specifications.

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

Solution Approach 2:

The attachment system is segmented into multiple independent latching elements rather than a single unified latch. This segmentation allows each latching element to be optimized for a specific wall thickness range, and the combination of segmented latches provides comprehensive coverage for various wall thicknesses without requiring multiple complete covering device variants.

Inventive Principle:
Principle #1Segmentation

2Reliability

If multiple covering device variants are produced for different wall thicknesses, then each variant is optimized for its specific thickness, but manufacturing effort and costs increase

Engineering Contradiction:
Improvesecure attachment reliabilityVSAvoidmanufacturing effort and costs
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

By designing latching elements with varying engagement geometries within a single covering device, the invention eliminates the need to manufacture multiple complete covering device variants for different wall thicknesses. This universal design maintains reliable attachment across all thicknesses while significantly reducing manufacturing complexity and costs.

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

Solution Approach 2:

Multiple latching elements with different engagement capabilities are merged into a single covering device structure. This combination allows the device to handle various wall thicknesses simultaneously, replacing what would otherwise require multiple separate device variants and reducing overall manufacturing effort.

Inventive Principle:
Principle #5Merging (Combining)

3Object-affected harmful factors

If the covering device is designed for complete closure of the opening, then it prevents dirt penetration effectively, but it requires precise matching to the opening dimensions

Engineering Contradiction:
Improvedirt penetration preventionVSAvoidcompatibility with different opening sizes
Core Design Contradiction:
Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The latching elements are designed with adjustable engagement positions and angles that can accommodate different opening dimensions while maintaining complete closure. This universal design allows the same covering device to effectively seal openings of various sizes without compromising dirt prevention or requiring precise custom matching.

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