Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current brake tester systems in motor vehicle workshops lack flexibility and safety due to the limitations imposed by physical cables connecting remote controls to test benches, restricting operation and increasing the risk of accidental control of incorrect machines.
Innovation Solution
A wireless remote control system utilizing near-field communication (NFC) for pairing with a radio receiver connected to the brake tester, allowing flexible spatial arrangement and ensuring secure operation by requiring physical proximity for pairing, with features like inductive charging and a light indicator for pairing status, minimizing accidental operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cable connection is used between the remote control and brake tester, then reliable assignment is ensured, but operational flexibility is limited by cable length
Solution Approach 1:
The patent extracts the pairing function from the cable connection by implementing NFC technology. The remote control and brake tester can be paired wirelessly through near-field communication, eliminating the physical cable while maintaining secure assignment. The pairing process creates a reliable wireless connection without the spatial limitations of a cable.
2Reliability
If a cable connection is used between the remote control and brake tester, then reliable assignment is ensured, but the remote control is always connected to a test bench
Solution Approach 1:
The patent implements pairing functionality that allows a single remote control to be paired with multiple brake testers sequentially. The NFC pairing mechanism enables the remote control to establish reliable wireless connections with different machines, providing universal control capability across multiple test benches without requiring physical cable connections to each device.
3Ease of operation
If wireless communication is used without pairing, then operational flexibility is improved, but the risk of accidental control of incorrect machines increases
Solution Approach 1:
The patent implements a pairing process that must be completed before the remote control can operate the brake tester. This preliminary action establishes a secure association between the remote control and the specific machine through NFC communication. The pairing creates a unique connection that prevents accidental operation of incorrect machines while maintaining wireless operational flexibility.
4Reliability
If NFC pairing is required for operation, then assignment security is maintained, but the system complexity increases
Solution Approach 1:
The patent replaces complex mechanical pairing systems with NFC near-field communication technology. Instead of using physical cables, manual configuration, or complex authentication mechanisms, the system uses simple tap-to-pair NFC interaction. This substitution maintains high assignment security while minimizing system complexity through the use of standardized wireless communication protocols.
