Solution Overview

Problem

Existing tile locking systems face issues with precise assembly, inability to adjust tightness, waste generation during disassembly, and compatibility with tiles of varying flange heights, leading to unstable connections and inefficiencies in assembly and disassembly processes.

Innovation Solution

A locking element with a multisided geometry head portion and a threaded body that allows for adjustable tension and reuse, featuring a bendable section for accommodating different tile inclinations and a recess design for compatibility with various aperture shapes, enabling secure engagement and easy assembly/disassembly without tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If snap coupling locking elements are used to connect adjacent layers, then assembly is simplified, but the connection stability deteriorates due to tolerance accumulation and inability to adjust tightness

Engineering Contradiction:
Improveassembly simplicityVSAvoidconnection stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The locking element transitions from a static snap-fit design to a dynamic threaded connection that allows for adjustment. The threaded body enables the locking element to be screwed into the aperture and adjusted to different positions, providing dynamic control over the connection tightness and compensating for manufacturing tolerances in the tiles and flanges.

Inventive Principle:
Principle #15Dynamics

2Productivity

If locking elements are designed with predetermined length for snap fitting, then assembly is quick, but adaptability to different flange heights deteriorates

Engineering Contradiction:
Improveassembly speedVSAvoidcompatibility with varying flange heights
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The locking element incorporates a threaded body that can be adjusted to different lengths by screwing it into the aperture to varying degrees. This dynamic adjustment capability allows the same locking element design to accommodate different flange heights and tile configurations, eliminating the need for multiple predetermined length variants.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The effective length of the locking element is changed by adjusting the threading depth into the aperture. This parameter change allows a single locking element design to serve multiple purposes across different tile types and flange heights, providing versatility without compromising assembly efficiency.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If snap coupling locking elements are used, then initial assembly is easy, but disassembly causes waste as locking elements must be destroyed

Engineering Contradiction:
Improveassembly easeVSAvoidwaste generation
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

The threaded connection allows the locking element to be easily unscrewed and removed from the aperture, enabling disassembly and reuse. This dynamic reversible connection eliminates the need to destroy the locking element during disassembly, contrasting with snap-fit designs that require drilling or breaking to remove.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The locking element is designed to be recovered and reused after disassembly. The threaded body can be completely removed from the aperture without damage, allowing it to be collected and used again in future assembly operations, thereby preventing waste and reducing material consumption.

Inventive Principle:
Principle #34Discarding and recovering

4Reliability

If precise distance control is required for snap locking engagement, then locking reliability improves, but manufacturing precision requirements worsen

Engineering Contradiction:
Improvelocking engagement reliabilityVSAvoiddistance between head portion and snap locking part
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

Instead of requiring precise predetermined distances in the locking element design, the threaded connection allows for dynamic adjustment during assembly. The locking element can be screwed in to the exact position needed, compensating for manufacturing tolerances in the tiles, apertures, and flanges, thereby achieving reliable engagement without stringent manufacturing precision requirements.

Inventive Principle:
Principle #15Dynamics
