Removable Snap Connection for Floor Covering Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor, wall, and ceiling covering systems face issues with expensive installation, visible screw heads, and the accumulation of dirt and debris in gaps between covering elements, requiring complete replacement of the covering system to clean or replace individual elements.
Innovation Solution
A non-destructively detachable and reconnectable snap-in connection system allows covering elements to be easily removed and reattached without damaging the connection, enabling cleaning and replacement of individual elements without full system replacement, suitable for various materials and applications including outdoor terraces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If covering elements are fastened to the substructure with a non-releasable snap-in connection, then the covering elements are securely fixed and cannot be accidentally detached, but the covering elements cannot be removed for cleaning or replacement without destroying the connection
Solution Approach 1:
The snap-in connection is designed with dynamic characteristics, allowing it to be easily engaged during installation but deliberately disengaged for maintenance. The connection transitions from a fixed state during operation to a removable state during maintenance, resolving the contradiction between secure fixation and ease of repair.
Solution Approach 2:
The snap-in connection is designed to be reusable rather than single-use. After covering elements are removed for cleaning or replacement, the same snap-in connections can be re-engaged, allowing the connection system to be recovered and reused multiple times without destruction.
2Adaptability or versatility
If gaps are left between covering elements, then material expansion and contraction is accommodated and ventilation is provided, but dirt and debris accumulate in the gaps requiring complete replacement of the covering system for cleaning
Solution Approach 1:
The covering system is segmented into individual removable covering elements rather than a fixed continuous structure. This allows gaps to be maintained for expansion accommodation while enabling individual elements to be removed for cleaning, preventing dirt accumulation problems.
Solution Approach 2:
Covering elements can be temporarily removed (discarded from the installed position) for cleaning purposes and then reinstalled (recovered). This reversible process allows complete cleaning of elements without permanent removal of the entire covering system.
3Reliability
If covering elements are screwed onto the substructure, then the covering elements are securely fastened, but screw heads are visible and the installation is expensive
Solution Approach 1:
The visible screw heads are extracted from the final assembly appearance. The snap-in connection mechanism is designed so that the fastening elements are hidden within the covering element or substructure, leaving only the clean aesthetic surface of the covering element visible.
