Vehicle Starting Button with Integrated Antenna Coil
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing PIC system for vehicle starting, which relies on a key fob with a transponder, suffers from aesthetic and layout limitations due to a separate fob holder installed in the cabin, and fails to function when the key fob's battery is discharged.
Innovation Solution
A starting button apparatus with a switch body, antenna coil, reciprocation housing, and rotation housing that allows power transfer to a discharged key fob, enabling signal transmission and vehicle starting through key fob insertion and rotation, without the need for a separate fob holder.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate fob holder is installed in the cabin to supply power to the transponder, then the vehicle can be started even when the key fob battery is discharged, but the aesthetic appearance inside the cabin is deteriorated and limitations are imposed on the layout of the vehicle
Solution Approach 1:
The patent combines the fob holder function with the starting button apparatus by integrating the antenna coil into the switch body. This merging eliminates the need for a separate fob holder device in the cabin, thereby maintaining aesthetic appearance while preserving the capability to start the vehicle when the key fob battery is discharged.
Solution Approach 2:
The starting button apparatus is designed to perform multiple functions: it serves as both the vehicle start button and the fob holder that supplies power to the transponder. The antenna coil integrated into the switch body enables the starting button to universally handle both normal starting operations and emergency starting when the key fob battery is discharged.
2Reliability
If a separate fob holder is installed in the cabin to supply power to the transponder, then the vehicle can be started even when the key fob battery is discharged, but the aesthetic appearance inside the cabin is deteriorated
Solution Approach 1:

This merging eliminates the need for a separate fob holder device in the cabin, thereby maintaining aesthetic appearance while preserving the capability to start the vehicle when the key fob battery is discharged.
3Reliability
If the antenna coil is integrated into the starting button apparatus, then power can be transferred to the key fob and signal transmission enabled, but the device structure becomes more complex
Solution Approach 1:
The starting button apparatus is designed to perform multiple functions: it serves as both the vehicle start button and the fob holder that supplies power to the transponder. The antenna coil integrated into the switch body enables the starting button to universally handle both normal starting operations and emergency starting when the key fob battery is discharged.
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 vehicle starting even with a discharged key fob battery, maintaining the vehicle's aesthetic appearance by integrating power transfer and signal transmission within the starting button apparatus, allowing seamless operation without a separate fob holder.
Implementation Method 1
The antenna coil is provided to the switch body to allow power to be applied to the key fob inserted into the key hole

AI summary
A starting button apparatus for a vehicle includes a switch body, an antenna coil, a reciprocation housing, and a rotation housing. The switch body includes a key hole therein, into which a key fob is inserted, and a starting button mounted thereto. The antenna coil is provided to the switch body to allow power to be applied to the key fob inserted into the key hole. The reciprocation housing is secured to an outer surface of the starting button and has a first inclined guide. The rotation housing is fitted around the reciprocation housing and has a second inclined guide which is slidably engaged with the first inclined guide so as to push the starting button when the inserted key fob is rotated.
