Vehicle Glazing Wire Dispensing Torque Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire cutting techniques for vehicle glazing panels, such as windscreens, face challenges in efficiently cutting through adhesive bonding materials without pre-cutting the wire and in controlling wire dispensing, especially when dealing with varying adhesive resistances.
Innovation Solution
A dispensing system with a winder unit and a wire store/dispenser device that includes adjustable brake means and a rotary device for controlled torque, allowing for 'slip cutting' and precise wire management, featuring a suction mount for secure attachment to the glazing panel and a spool system for winding and unwinding the cutting wire.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wire cutting techniques are used to cut through adhesive bonding materials, then the glazing panel can be removed, but the wire dispensing control is difficult especially when dealing with varying adhesive resistances
Solution Approach 1:
The brake means is made adjustable to dynamically change the braking effect during operation. The brake can be tightened to increase braking effect when encountering high adhesive resistance, or relaxed to reduce braking effect when adhesive resistance is low, allowing the system to adapt to varying cutting conditions without requiring a completely complex dispensing control system
Solution Approach 2:
The braking parameter of the brake means is made variable through adjustment mechanisms. By changing the braking parameter (braking force) in response to varying adhesive resistances, the system achieves controlled wire dispensing without requiring complex electronic or automated control systems
2Ease of operation
If a spool system is used to wind and dispense cutting wire, then wire management is improved, but wire tangling occurs during dispensing
Solution Approach 1:
The brake means provides dynamic control over wire dispensing from the spool. By adjusting the braking effect during operation, the system prevents wire from dispensing too quickly or uncontrollably, which would cause tangling, while still allowing smooth wire feed when needed
Solution Approach 2:
The operator can sense the resistance encountered during cutting and provide feedback by adjusting the brake means accordingly. This manual feedback loop allows the operator to maintain proper wire tension and dispensing rate, preventing tangling while keeping the system simple
3Productivity
If cutting wire is paid out from the dispenser unit during slip cutting, then adhesive bonding materials can be cut efficiently, but operator effort and physical strength requirements increase
Solution Approach 1:
The brake means acts as an intermediary between the operator and the wire dispensing system. Instead of the operator directly controlling wire payout force, the brake means mediates by providing controlled resistance, converting manual brake adjustment into controlled wire tension and dispensing
Solution Approach 2:
The system allows the adhesive bonding material itself to provide feedback through the cutting resistance it presents. The operator adjusts the brake to match this resistance, and the system self-regulates wire dispensing based on the actual cutting conditions, reducing the need for operator strength
