Tile Spacer with Removable Arms for Wall Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tile spacers are difficult to remove after tiles are glued in place, leading to issues like grout cracking and tiles falling due to gravity, especially on walls and ceilings, where they become stuck and cause aesthetic and safety problems.
Innovation Solution
A tile spacer with a body portion, flange portions, and arm members that can be securely fastened to the installation surface using a retaining mechanism, allowing for easy removal after the tiles are affixed, featuring a tapered tip and radially offset arm members for uniform spacing and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If flat plastic or wood cross-shaped spacers are used to provide equal spacing between tiles, then uniform tile spacing is achieved, but the spacers become difficult to remove after tiles are glued in place
Solution Approach 1:
The spacer transitions from a static flat design to a dynamic three-dimensional structure with arms that can be inserted between tiles and a body that extends beyond the tile surface. This dynamic configuration allows the spacer to adapt to different stages of tile installation and facilitates easy removal after grouting.
Solution Approach 2:
The invention transitions from a two-dimensional flat spacer to a three-dimensional structure with arms extending perpendicular to the tile surface. This dimensional change allows the spacer to provide spacing in multiple directions and enables easy removal by lifting the body portion vertically after the tiles are set.
2Ease of operation
If spacers are left in place and covered with grout to avoid removal difficulties, then spacer removal is avoided, but cracks in the grout occur because grout does not adhere to the spacers
Solution Approach 1:
The spacer body is extracted from the grout joint space and positioned outside the area where grout is applied. The grout is applied only between the tiles, excluding the spacer body, which prevents adhesion issues and grout cracking while maintaining the spacer's spacing function during installation.
Solution Approach 2:
The arm members act as intermediaries that provide spacing between tiles while the body portion serves as an external reference structure. This separation allows grout to adhere properly to the tiles without contacting the spacer, eliminating the adhesion problem while maintaining spacing functionality.
3Manufacturing precision
If spacers are used on wall installations, then tile spacing is maintained, but the spacers get stuck between tiles due to gravity pressing upper tiles against them
Solution Approach 1:
The spacer design allows it to transition from being pressed against tiles during installation to being easily lifted away after grouting. The arm members provide structural support during installation while the body portion can be vertically extracted after the tiles are set, overcoming the gravity-related removal difficulty on walls.
Solution Approach 2:
By extending the spacer body vertically beyond the tile surface, the design creates a removal path in the vertical dimension that is not blocked by gravitational forces pressing tiles against the spacer. This allows easy vertical extraction of the spacer from wall installations after grouting.
4Manufacturing precision
If spacers cannot be removed from side walls or ceilings, then spacing is maintained, but grout cracking causes tiles to fall off which creates safety hazards
Solution Approach 1:
The spacer body is extracted from the grout application zone and positioned externally, allowing complete grout coverage between tiles without adhesion interference. This prevents grout cracking that would otherwise cause tile detachment and safety hazards while maintaining precise spacing during installation.
Solution Approach 2:
The spacer is designed as a temporary installation aid that is discarded (removed) after serving its spacing function. Once the tiles are set and grouted, the spacer is easily removed and discarded, preventing it from becoming a source of grout cracking and tile detachment that would create safety hazards.
