Solution Overview
Problem
Existing technologies for manufacturing window and door frames face challenges in maintaining continuity and coplanarity of external surfaces at angular junctions, requiring complex assembly and limited contact surfaces, which complicates the alignment and tightening process.
Innovation Solution
A tightening and aligning device comprising a main body with two plate portions at right angles and removable trolleys connected by breakable bridges, allowing for easy assembly and providing a large contact surface through serrated or notched surfaces to ensure coplanarity of joined sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a tightening and aligning apparatus is made of three pieces assembled with mortise and tenon joints, then the apparatus can be assembled and connected, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The patent combines three separate pieces (main body, first trolley, second trolley) into a single integrated piece made of transparent material. This merging eliminates the need for complex mortise and tenon joint assembly while maintaining the functional integrity of the apparatus, directly resolving the contradiction between ease of assembly and device complexity.
2Device complexity
If the contact surface between cams and profiled element borders is made small, then the apparatus structure is compact, but the tightening and aligning effectiveness is reduced
Solution Approach 1:
The patent transitions from point-contact cams to surface-contact trolleys by extending the contact interface into an additional dimensional space. The trolleys provide large planar contact surfaces with the profiled element borders, significantly improving tightening and aligning effectiveness while maintaining apparatus compactness through the integrated single-piece design.
3Adaptability or versatility
If the apparatus is made of multiple separate pieces, then each component can be optimized independently, but the overall device thickness increases
Solution Approach 1:
The patent merges the main body and both trolleys into a single integrated piece of transparent material, eliminating the thickness accumulation that would result from stacking multiple separate components. This integration maintains the optimized functional features of each component while reducing the overall device thickness.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device simplifies the assembly and alignment process, ensures effective coplanarity, and provides a reliable, easy-to-install solution with reduced thickness, enhancing the manufacturing efficiency of window and door frames.
Implementation Method 1
two trolleys removably connected to said main body by means of bridges of breakable material
Implementation Method 2
The internal border of the body is tilted by an angle with respect to the external border and the internal border of the trolley is tilted by the same angle with respect to the external border of the trolley. So, during the sliding of the trolley, the external border of the trolley moves away from the external border of the body, remaining parallel to the external border of the body and exerting pressure on the second rib of the section
