Compact Wire Winder Unit for Vehicle Glazing Panel Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for removing vehicle glazing panels, such as windshields, are inefficient due to the need for multiple suction cups and complex setups, which increase space requirements and operational effort.
Innovation Solution
A compact wire winder unit with a single suction mount and adjustable wire guide elements allows for efficient cutting of glazing panels by positioning winder spools on either side of the suction mount's diameter, reducing space usage and operational complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple suction cups are used to mount the wire winder unit, then the mounting stability is improved, but the device complexity and space requirements increase
Solution Approach 1:
The patent combines multiple suction cup functions into a single suction mount that can securely hold the wire winder unit. This single mount integrates the mounting functionality that would otherwise require multiple separate suction cups, thereby reducing device complexity while maintaining mounting stability through the unified design of the suction mount.
2Reliability
If multiple suction cups are used to mount the wire winder unit, then the mounting stability is improved, but the space requirements increase
Solution Approach 1:
The patent merges multiple suction cup mounting points into a single compact suction mount structure. This consolidation reduces the overall space occupied by the mounting device while maintaining secure attachment through the integrated design, thereby reducing the area required on the vehicle surface for mounting the wire winder unit.
3Manufacturing precision
If fixed wire guide elements are used, then the manufacturing precision is improved, but the adaptability to curved glass surfaces decreases
Solution Approach 1:
The patent employs wire guide elements that are adjustable or movable rather than completely fixed, allowing them to adapt to curved glass surfaces while maintaining adequate alignment precision. The dynamic adjustment capability enables the guide elements to conform to surface curvature, resolving the contradiction between fixed precision and adaptive versatility.
Solution Approach 2:
The patent allows adjustment of wire guide element parameters such as position and orientation to accommodate curved glass surfaces. By enabling parameter changes in the guide element configuration, the system maintains manufacturing precision while gaining adaptability to different surface geometries, including curved windshields.
4Power
If the winder spools are positioned far from the suction mount, then the wire tensioning is improved, but the device compactness decreases
Solution Approach 1:
The patent positions the winder spools in a spatial arrangement relative to the suction mount that optimizes both tensioning capability and compactness. By utilizing three-dimensional positioning rather than simple linear spacing, the design achieves adequate wire tensioning while maintaining a compact overall unit volume through strategic spatial configuration of the spools around the suction mount.
