Solution Overview

Problem

Existing threshold bars and edging elements face challenges in aesthetics, adaptability to varying heights, and reliable gluing methods, leading to high manufacturing costs and storage difficulties, as well as issues with adhesive thickness and cohesion over time.

Innovation Solution

A border element system featuring an elongated section with adhesive portions, wedges with elastically deformable jaws, and a clip-shaped head, allowing for easy gluing and adaptation to different heights, combined with a sliding mechanism for nail or dowel installation, enabling use as both a threshold bar and curb stop.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional glued edging elements are used, then installation is simple, but adhesive thickness causes aesthetic problems and cohesion failure over time

Engineering Contradiction:
Improveinstallation simplicityVSAvoidadhesive cohesion
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The edging element is divided into multiple sections with individual adhesive portions, allowing each section to be independently secured without requiring thick continuous adhesive layers. This segmentation enables reliable bonding while maintaining aesthetic appearance by reducing visible adhesive.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Wedges are positioned beforehand to provide mechanical support and alignment before adhesive application. This preliminary mechanical securing allows the adhesive to be applied in thinner, more controlled layers, improving both aesthetics and reliability.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If multiple types of edging elements are manufactured to adapt to varying heights, then adaptability improves, but manufacturing costs and storage complexities increase

Engineering Contradiction:
Improveheight adaptationVSAvoidproduct variety
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The edging element incorporates adjustable components such as wedges and compressible adhesive portions that can be modified during installation to accommodate different height requirements. This dynamic adjustability eliminates the need for multiple fixed-height product variants.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

A single edging element design serves multiple height requirements through adjustable features, making it a universal solution that replaces multiple specialized products. The element can be adapted to function as both threshold bar and curb stop.

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

3Reliability

If adhesive portions are applied thickly to ensure cohesion, then reliability improves, but aesthetic appearance deteriorates

Engineering Contradiction:
Improveadhesive cohesionVSAvoidaesthetic appearance
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The adhesive system is segmented into multiple discrete adhesive portions distributed along the edging element. This segmentation allows each portion to be applied in thin, aesthetically pleasing layers while collectively providing sufficient cohesion through cumulative bonding strength.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The adhesive portions are applied as thin films or layers rather than thick masses. These thin adhesive films maintain aesthetic appearance by being visually imperceptible while providing reliable bonding when distributed across multiple segments.

Inventive Principle:
Principle #30Flexible shells and thin films

4Strength

If traditional nail installation methods are used, then mechanical strength is achieved, but installation complexity increases due to hole preparation and alignment requirements

Engineering Contradiction:
Improvemechanical strengthVSAvoidinstallation complexity
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The adhesive bonding system is merged with optional mechanical reinforcement elements. The adhesive provides primary bonding strength while eliminating the need for complex hole preparation and alignment procedures associated with traditional nail installation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

Adhesive portions serve as an intermediary bonding medium that simplifies the installation process. Instead of requiring direct mechanical fastening through holes and nails, the adhesive mediator provides reliable bonding while allowing for simpler installation procedures.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The spacer (9) has a foot resting on ground, and a clamp-shaped head opened opposite the foot, where the spacer is formed as a single piece using plastic material. The head is equipped with two jaws that are directed vertically and have different lengths. An opening of the head receives an adhesive portion (62) of an edging element (5) that is formed of an elongated section. One of the jaws is deformable elastically to temporarily close the head at a vicinity of the opening. The foot is equipped with a rupture zone (922). Independent claims are also included for the following: (1) an edging element system comprising an elongated section (2) a method for installing an edging element system.
