Stationary Vehicle Key Tester Simulating Antenna Positions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle key testing requires physically walking around a vehicle to determine if individual antennas can receive signals from the key, making the process time-consuming and inefficient.
Innovation Solution
A stationary vehicle key testing device with a housing, antennas, and a control circuit that simulates vehicle antennas and activates the key's wireless functions, allowing for testing without physically using the key on a vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a tester walks around the vehicle to test each antenna position, then the testing can be performed on actual vehicle conditions, but the testing time becomes excessively long
Solution Approach 1:
The patent creates a stationary testing device that copies the essential functionality of vehicle antennas and key fobs. Instead of testing on actual vehicles by walking around, the device uses replicated antenna elements arranged in specific patterns to simulate multiple vehicle antenna positions simultaneously, enabling comprehensive testing in a fixed location.
Solution Approach 2:
The testing device is designed to test multiple key fob functions (door unlock, trunk release, panic alarm, remote start) across multiple simulated antenna positions simultaneously. A single device performs what would otherwise require multiple vehicle visits, making the testing process universal and efficient.
2Measurement precision
If multiple antennas are tested on different vehicle positions, then complete coverage of all receiving antennas is achieved, but the complexity of the testing process increases
Solution Approach 1:
The patent combines multiple antenna testing functions into a single stationary device. Multiple antenna elements are integrated within one housing, and the control system manages all testing operations from a centralized interface. This merging eliminates the need for separate testing procedures for each antenna position.
Solution Approach 2:
The testing device acts as an intermediary between the key fob and the vehicle antennas. It provides a controlled intermediate environment where signals can be transmitted and received without requiring physical access to actual vehicle antennas, simplifying the testing interface while maintaining comprehensive coverage.
