Portable Window Lift Controller for Unwired Vehicle Troubleshooting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window lift assemblies in vehicles often require troubleshooting during assembly, but they are not yet wired to controls or a battery, necessitating a portable solution for operation.
Innovation Solution
A portable window controller with a hand-sized housing and a momentary switch that automatically cuts power to the regulator motor when returned to a home position, featuring a display for power measurement and visual indicators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a portable window controller is designed to fit in a hand for ease of operation, then the device size is reduced, but the internal components space is limited
Solution Approach 1:
The patent integrates multiple functional components within the compact controller housing by nesting them together. The momentary switch, display module, and control circuitry are arranged in a nested configuration where smaller components are housed within or alongside larger ones, maximizing space utilization while maintaining hand-portable dimensions.
2Loss of energy
If a momentary switch is used to automatically cut power to the motor, then energy efficiency is improved, but the control mechanism complexity increases
Solution Approach 1:
The momentary switch is designed with an inherent spring mechanism that automatically returns the switch to its default state after actuation. This self-service feature eliminates the need for additional control circuitry or programming to cut power, as the mechanical design itself provides the automatic power termination function, thereby reducing overall system complexity.
3Loss of information
If visual indicators and display are added for power measurement, then user feedback is improved, but the device complexity increases
Solution Approach 1:
The patent employs color-changing visual indicators such as LED lights that change color or illuminate to indicate different power states and operational statuses. This provides intuitive visual feedback to the user about power consumption and system state without requiring complex display interfaces or multiple indicator components, thereby maintaining simplicity while improving information feedback.

AI summary
A portable window controller for operating window lift assemblies of multiple vehicles includes a controller housing that is sized to fit in a hand and a control switch that extends outward from the housing and can be actuated by the hand. The control switch is a momentary switch that is biased toward a home position and terminates power to a regulator motor when the control switch is placed in the home position.
