Remote Glass Removal Tool with Vacuum Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glass removal systems require multiple people to operate and remove windshields from automobiles, due to the unwieldy nature of the glass and the need for manual operation from inside the vehicle, making the process inefficient and labor-intensive.
Innovation Solution
A glass removal tool equipped with a motor, spool, cutting medium, vacuum pump, and remote control device, allowing a single user to operate the tool from outside the vehicle, with the vacuum pump creating a vacuum force to attach to the glass and the motor-driven cutting medium to sever the sealant, enabling efficient removal of windshields without additional personnel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation from inside the vehicle is used, then the glass removal can be performed, but multiple people are required and the process is labor-intensive
Solution Approach 1:
The patent replaces manual mechanical operations with an automated motor-driven system. The motor (18) drives the spool (20) to retract the cutting medium (22), automatically cutting through the sealant (84) without requiring manual manipulation from inside the vehicle. This substitution enables remote operation from outside the vehicle while maintaining effective glass removal.
Solution Approach 2:
The patent introduces a vacuum pump (24) and attachment mechanism (26) as intermediaries to secure the tool to the glass surface. The vacuum pump creates a vacuum force that couples the attachment mechanism to the inner surface of the glass, allowing the tool to be operated remotely from outside the vehicle while remaining firmly attached during the cutting process.
2Reliability
If multiple people operate the tool, then the glass can be removed, but the process requires coordination and additional personnel
Solution Approach 1:
The patent implements self-service through automated functions. The motor automatically retracts the cutting medium to cut the sealant, and the vacuum pump automatically maintains attachment to the glass surface. This eliminates the need for multiple operators to manually coordinate actions, as the system performs its own functions autonomously once activated.
Solution Approach 2:
The patent replaces the mechanical coordination required between multiple operators with an automated control system. The remote control device (14) allows a single operator to control the motor and vacuum pump from outside the vehicle, substituting the need for multiple people physically present and coordinating their actions inside the vehicle.
3Force
If the cutting medium is manually pulled, then the sealant can be cut, but significant physical force is required
Solution Approach 1:
The patent replaces manual pulling force with a motor-driven spool system. The motor (18) provides the force to retract the cutting medium (22) onto the spool (20), creating the necessary cutting force to sever the sealant (84) without requiring an operator to manually pull with significant physical effort.
Solution Approach 2:
The patent employs periodic action through the motor's continuous rotation of the spool. The motor drives the spool to gradually retract the cutting medium in a continuous periodic motion, maintaining consistent cutting force through the sealant rather than requiring intermittent manual pulling efforts.
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
Enables a single user to quickly and efficiently remove windshields by allowing remote operation of the tool, reducing the need for multiple workers and minimizing movement in and out of the vehicle, thus streamlining the windshield replacement process.
Implementation Method 1
The vacuum pump creates a vacuum force to couple the attachment mechanism to an inner surface of the piece of glass
