Movable Stop with Adjustable Tensioners for Glass Panel Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of glass panels with aluminum profiles is hindered by measurement variances due to imprecise edge polishing, leading to inaccuracies and the need for subsequent wedging or fitting, which increases costs and reduces productivity.
Innovation Solution
An apparatus with a main support, press head, and movable stop featuring adjustable tensioning elements and lateral positioning stops, allowing for precise calibration and correction of measurement defects during the assembly process, ensuring a rectangular panel shape and efficient assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If glass panes are cut with high precision (1/10,000 tolerance), then cutting accuracy is improved, but subsequent polishing processes introduce measurement variances that create assembly problems
Solution Approach 1:
The patent applies preliminary action by pre-calibrating the movable stop with adjustable tensioning elements to compensate for expected polishing variances before assembly. The stop is adjusted in advance to account for the 0.5-1.5mm polishing tolerance, allowing the system to preemptively correct measurement issues that will arise during subsequent polishing operations.
Solution Approach 2:
The patent employs parameter changes by making the stop position adjustable through tensioning elements that can be calibrated to different positions. This allows the system to change the stop parameter to compensate for polishing variances, transforming a fixed measurement system into an adaptable one that can accommodate the 0.5-1.5mm tolerance range introduced by polishing.
2Ease of operation
If traditional worktables are used for assembling glass and aluminum profiles, then assembly simplicity is maintained, but measurement inaccuracies require subsequent wedging or fitting operations
Solution Approach 1:
The patent introduces an intermediary element - the movable stop with adjustable tensioning elements - that mediates between the simple worktable setup and the requirement for precise assembly. This intermediary component provides the necessary measurement correction without requiring complex machinery, maintaining operational simplicity while eliminating the need for time-consuming wedging or fitting operations.
3Manufacturing precision
If subsequent wedging or fitting operations are performed to correct measurement variances, then panel assembly accuracy is improved, but operation time and costs increase
Solution Approach 1:
The patent applies preliminary action by pre-calibrating the movable stop to compensate for expected polishing variances before assembly begins. This preliminary adjustment eliminates the need for time-consuming corrective operations like wedging or fitting that would otherwise be required after assembly to achieve proper rectangularity and fit.
