Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing dry method for fixing finishing materials like bricks requires a secondary operation, increasing labor and material costs, and construction time, while also being prone to poor quality finishes when performed by unskilled individuals.
Innovation Solution
A system that includes a quadrangle bar, fixing brackets with engaging and load-supporting plates, and a joint forming member, allowing bricks to be securely fixed without secondary operations through a locking engagement mechanism, using elastic plates for stability and thermal break materials to prevent moisture and heat transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a separate fixing member is used to attach finishing material to walls, then construction time is reduced and heat insulation is improved, but a secondary fixing operation is required which increases labor cost, material cost, and construction time
Solution Approach 1:
The fixing member integrates multiple functions into a single component: the first fixing portion attaches to the wall, the second fixing portion secures the finishing material, and the connecting portion links them. This merging eliminates the need for separate fixing operations and additional materials, resolving the contradiction between construction speed and system complexity.
Solution Approach 2:
The fixing member serves multiple purposes simultaneously: it provides structural attachment to the wall, secures the finishing material through engagement, and maintains spatial positioning. This multi-functionality allows the system to achieve both rapid installation and simplified design by consolidating what would otherwise require multiple separate components and operations.
2Reliability
If secondary fixing operation is required to secure finishing material to fixing member, then initial attachment is achieved, but labor cost and material cost increase
Solution Approach 1:
The fixing member is pre-configured with the first fixing portion, second fixing portion, and connecting portion as an integrated unit. The preliminary design ensures that both wall attachment and finishing material securing are built into the same component, eliminating the need for secondary fixing operations and reducing both labor and material costs while maintaining reliability.
Solution Approach 2:
The fixing member is designed to perform both fixing functions automatically through its integrated structure. Once installed, the connecting portion self-secures the finishing material without requiring additional fixing operations, making the system self-sufficient and reducing dependency on skilled labor for secondary operations.
3Ease of operation
If secondary fixing operation is performed by unskilled personnel, then installation can be completed, but finish quality is poor and building structure appearance is compromised
Solution Approach 1:
The integrated fixing member design performs the precise positioning and securing functions automatically through its mechanical structure. The connecting portion's engagement mechanism ensures proper alignment and secure attachment without requiring skilled judgment or manual adjustment, allowing unskilled personnel to achieve high finish quality while maintaining ease of operation.
