Solution Overview

Problem

Existing building components with covering elements, such as brick slips, face challenges in maintaining a strong attachment to the elongate support structure, particularly when adhesive bonds weaken or fail, posing a risk of elements detaching, especially in populated areas.

Innovation Solution

Incorporating mechanical retaining means, such as male and female interlocking components, including flange-like projections and recesses, to enhance the adhesive bond between covering elements and the elongate support structure, providing a backup mechanism to prevent displacement even if the adhesive fails.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If adhesive bonding is used to attach covering elements to the building component, then the attachment process is simple and the adhesive provides initial bonding, but the adhesive bond may weaken or fail over time, causing covering elements to detach

Engineering Contradiction:
Improveease of attachmentVSAvoidattachment reliability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The attachment system is segmented into two independent functions: adhesive bonding for initial attachment and mechanical retaining means for long-term reliability. The mechanical fixing means includes separate components (protrusions on the building component and corresponding recesses on the covering element) that work independently but complement the adhesive system, ensuring that if the adhesive fails, the mechanical features prevent detachment.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mechanical retaining means acts as a pre-prepared backup mechanism that is already in place before the adhesive bond might fail. The protrusions and recesses are pre-configured to engage automatically when the covering element is installed, providing a fail-safe mechanism that prevents detachment even if the adhesive deteriorates over time.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

2Reliability

If mechanical retaining means are added to enhance attachment reliability, then the attachment strength and reliability improve, but the device complexity increases

Engineering Contradiction:
Improveattachment reliabilityVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The mechanical retaining means is merged with the existing building component structure. The protrusions are integrated into the building component itself rather than being separate attachments, and the recesses are formed as part of the covering element design. This integration minimizes additional complexity while achieving reliable mechanical retention.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The mechanical retaining features are applied locally at critical attachment points rather than throughout the entire structure. The protrusions and recesses are positioned specifically where the covering element meets the building component, providing targeted mechanical retention only where needed to prevent detachment, rather than adding complexity to the whole assembly.

Inventive Principle:
Principle #3Local quality

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

The mechanical fixing means ensure the covering elements remain securely attached to the support structure, preventing detachment and enhancing stability, especially in high-traffic installations.

Implementation Method 1

The elongate support structure is adapted to receive an adhesive for adhesively bonding the one or more covering elements to the elongate support structure

Methodology Applied
Scientific EffectAdhesive bonding: Adhesive

Implementation Method 2

The mechanical fixing means are adapted to enhance the adhesive bond between the covering elements and the elongate support structure by forming an interlock with the covering elements. The interlock can limit or prevent the lateral and/or longitudinal and/or vertical displacement of the covering elements with respect to the elongate support structure

Methodology Applied
Scientific EffectMechanical interlocking: Mechanical Fastener
