Integrated ECU and Battery Terminal Mounting for Vibration Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing assembly techniques for mounting the engine multifunction control unit (CMM) and battery connection terminal (BFT) in the front block of electric traction battery-powered motor vehicles are inefficient, requiring disassembly and lack adequate protection against vibrations and water damage.
Innovation Solution
A mounting bracket system comprising an ECU bracket and a terminal bracket, secured with snap-on mechanisms and fasteners, which allows the CMM and BFT to be sandwiched and aligned, providing vibration resistance and protection, while facilitating assembly and integration with the vehicle's support block.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If standard assembly techniques are used to mount the CMM and BFT terminal separately, then each component can be individually secured, but the assembly process becomes complex and requires disassembly of previous mounting structures
Solution Approach 1:
The patent combines the CMM mounting bracket and BFT terminal mounting bracket into a single integrated bracket assembly. This merging allows both components to be mounted simultaneously in one operation, eliminating the need for separate mounting processes and disassembly of terminal supports, thereby simplifying the overall assembly process while reducing structural complexity
Solution Approach 2:
The integrated bracket serves multiple functions: it mounts both the CMM computer and the BFT terminal, provides structural support, and enables simultaneous installation. This multi-functionality reduces the number of separate components needed and simplifies the mounting procedure without compromising individual component security
2Reliability
If the CMM is mounted without adequate protection, then assembly is simpler, but the CMM is vulnerable to damage from vibrations and water during vehicle operation
Solution Approach 1:
The mounting bracket incorporates protective features in advance, including vibration isolation elements and water drainage pathways. The integrated design provides structural rigidity to resist vibrations during vehicle operation, while built-in drainage holes prevent water accumulation that could damage the CMM or terminal components
Solution Approach 2:
The mounting bracket acts as an intermediary structure between the vehicle chassis and the sensitive electronic components (CMM and BFT terminal). It provides mechanical coupling while isolating the components from harmful vibrations and water exposure through its designed mounting geometry and drainage features
3Productivity
If separate mounting brackets are used for CMM and BFT terminal, then each component has dedicated support, but assembly time increases and production efficiency decreases
Solution Approach 1:
By merging the CMM bracket and BFT terminal bracket into one integrated assembly, the patent enables both components to be installed simultaneously in a single mounting operation. This eliminates the sequential installation process, reduces assembly time, and improves production efficiency without making the installation process more difficult
Solution Approach 2:
The terminal support is pre-integrated into the CMM mounting bracket structure during manufacturing. This preliminary integration means that during vehicle assembly, the entire combined structure is installed in one step, eliminating the need for separate mounting operations and thereby increasing productivity
