Mortar Application Frame with Guide Edges for Uniform Joints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mortar application devices fail to ensure even and proportional application, leading to uneven joints, wastage of mortar, and thermal bridges in building construction, which affects the aesthetic appeal and energy efficiency of the wall.
Innovation Solution
A quadrangular frame with elongated tubular fastenings on one side for stable positioning and a central strip to create air spaces, ensuring even mortar application and preventing thermal bridges, while handles facilitate easy handling and adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional mortar application methods are used, then application speed is maintained, but joint uniformity and proportioning precision deteriorate
Solution Approach 1:
The patent introduces a mortar board with guide edges as an intermediary tool between the mortar bucket and the wall. The guide edges physically constrain the mortar application area, ensuring uniform joint thickness while maintaining efficient mortar placement. This mediator tool resolves the contradiction by providing both precision guidance and rapid application capability.
Solution Approach 2:
The mortar board is pre-positioned against the wall with its guide edges aligned to define the exact joint boundaries before mortar application. This preliminary positioning establishes the precise application zone in advance, ensuring uniform joints without requiring slow, careful application, thus maintaining both precision and productivity.
2Reliability
If excessive mortar is applied to ensure coverage, then coverage completeness is improved, but mortar wastage increases
Solution Approach 1:
The mortar board creates locally defined application zones through its guide edges, confining mortar to precisely where it is needed on the wall. This local confinement ensures complete coverage within the joint area while preventing mortar from spreading beyond required boundaries, thereby eliminating wastage without compromising coverage completeness.
3Manufacturing precision
If manual mortar application is used, then flexibility is maintained, but application evenness and proportioning deteriorate
Solution Approach 1:
The mortar board serves as a mechanical intermediary that translates manual operation into precise, even mortar application. The guide edges provide physical constraints that ensure uniform joint thickness regardless of operator skill, while the board itself remains easily maneuverable, preserving operational flexibility while achieving consistent results.
