Vehicle Glazing Panel Cut Out System Using Slip Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle glazing panel removal techniques, such as those described in WO2006/030212, face challenges in efficiently cutting through adhesive bonding materials without wire slippage and require pre-cutting of the entire wire length, which can be cumbersome and inefficient.
Innovation Solution
A glazing panel cut out system comprising a dispenser unit and a winder unit with spools and a brake mechanism, allowing for 'slip cutting' by paying out wire from a dispenser unit and winding it onto spools, enabling efficient cutting without pre-cutting the entire wire length, and utilizing a suction mount and guide wheels for secure mounting and smooth wire management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wire cutting techniques are used to remove glazing panels, then cutting through adhesive bonding material is achieved, but wire slippage occurs and pre-cutting of entire wire length is required
Solution Approach 1:
The wire system transitions from a static pre-cut configuration to a dynamic pay-out system where the wire is continuously fed from a dispenser during the cutting operation, allowing the wire length to adapt to the actual cutting path required
Solution Approach 2:
The wire management system is divided into separate functional components: a dispenser unit that holds and pays out the wire, and a winder unit that collects the wire, eliminating the need for a single long pre-cut wire
2Ease of manufacture
If the entire wire length is pre-cut, then the wire is ready for use, but the setup process becomes cumbersome and inefficient
Solution Approach 1:
The wire is pre-loaded onto the dispenser unit in a compact form, performing the preparation action before the actual cutting operation begins, so that no time-consuming setup is required during the cutting process itself
Solution Approach 2:
The dispenser unit automatically feeds the wire during cutting operations, eliminating the need for manual wire handling and adjustment by the operator throughout the cutting process
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 system facilitates efficient cutting of vehicle glazing panels by allowing 'slip cutting' and reducing operator complexity, enabling effective removal with minimal setup and physical effort, while ensuring the second free end of the wire is cut only when a significant portion of the windscreen is cut out.
Implementation Method 1
mounting means for securing the dispenser unit and winder unit to opposed surfaces of the glazing panel
Implementation Method 2
The brake or dag device may be a patch of adhesive tape secured to the glazing panel overlaying a length of the wire extending from the dispenser unit

AI summary
A glazing panel cut out system for use with a cutting wire (41) in cutting out a vehicle glazing panel cut out procedure has a dispenser unit (2) for dispensing cutting wire and a winder unit (1) for winding the wire, both being mounted to the glazing panel during use. The winder unit has one or more winder spools (4,5) for winding the cutting wire (41) dispensed from the dispenser (2). The cutting wire is paid out from the dispenser whilst mounted to the glazing panel during the cut out procedure.
