Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The replacement of brake components in a vehicle braking system with components of different specifications, lower strength, or faster wear characteristics can adversely affect the system's performance and useful life, highlighting the need for ensuring that only correctly specified replacement parts are used.
Innovation Solution
A method involving an electronic diagnostic device connected to the braking system via a CAN bus, which uses codes to verify that replacement components match the system's specifications, preventing incorrect replacements and ensuring proper maintenance through automated control of the replacement process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual replacement of brake components is allowed without verification, then ease of operation is improved, but reliability deteriorates due to risk of incorrect parts installation
Solution Approach 1:
The system reads identification codes from replacement components and compares them against required specifications, providing immediate feedback verification. The controller receives code data from the replacement component via CAN bus, performs automated comparison, and only permits installation when codes match, ensuring reliability while maintaining ease of operation.
Solution Approach 2:
The patent replaces manual visual inspection and mechanical verification of component compatibility with an automated electronic code verification system. The electronic diagnostic device reads identification codes and the controller automatically determines compatibility, substituting human judgment with automated electronic verification.
2Manufacturing precision
If code verification system is implemented, then manufacturing precision is improved through automated component matching, but device complexity increases
Solution Approach 1:
The electronic diagnostic device performs multiple functions: it reads identification codes from components, transmits data via CAN bus, compares codes against specifications, and controls the replacement actuator. This multi-functional approach consolidates what could be separate complex systems into a single versatile device, reducing overall system complexity while maintaining precise component matching.
Solution Approach 2:
The system uses the existing CAN bus communication infrastructure already present in modern vehicles for data transmission, rather than requiring a separate dedicated communication system. This self-service approach leverages available resources to reduce device complexity while achieving precise component verification.
3Loss of time
If automated replacement control is implemented, then loss of time is reduced through streamlined replacement process, but ease of operation worsens due to additional verification steps
Solution Approach 1:
The system performs code verification automatically and in real-time during the replacement process. The identification code is read and verified before the replacement actuator enables component installation, ensuring that time is not wasted on incompatible parts while the automated nature of the verification minimizes the additional steps required from the operator.
