Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical assemblies for vehicles are often complex and lack sufficient functionality, particularly when integrated with removable or reconfigurable seats, such as those with airbags, and do not adequately address the need for efficient activation and monitoring of safety devices during crash events.
Innovation Solution
An electrical assembly comprising a support assembly and a track assembly with a controller and safety devices, where the controller receives signals to activate safety devices like airbags, and includes redundant power supplies and communication mechanisms to ensure functionality even without primary power, allowing for selective mechanical and electrical connections to manage safety device activation and monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electrical assembly is designed with selective mechanical and electrical connections for removable seats, then adaptability and versatility are improved, but device complexity increases due to multiple connection configurations and routing requirements
Solution Approach 1:
The electrical assembly is designed with universal connection capabilities that allow the same assembly to interface with both fixed and removable seats through standardized tracks and routing paths. The controller and safety devices can serve multiple functions depending on the seat configuration, eliminating the need for completely separate assembly designs.
Solution Approach 2:
The electrical assembly incorporates dynamic routing paths for conductors and signal transmission that can adapt to different seat positions and configurations. The selective mechanical and electrical connections allow the system to reconfigure itself based on whether seats are installed in forward-facing, rear-facing, or removed states.
2Reliability
If redundant power supplies and communication mechanisms are added to ensure functionality during power disruptions, then reliability is improved, but device complexity and cost increase
Solution Approach 1:
The electrical assembly incorporates a secondary power supply that is activated beforehand when the primary power supply fails. This redundant power source is specifically designed to provide power to the controller and safety devices during crash events when the primary power may be disrupted, ensuring continuous operation of critical safety functions.
Solution Approach 2:
The controller acts as an intermediary that manages power distribution and signal routing between the primary and secondary power supplies. It intelligently switches between power sources and coordinates the activation of safety devices, simplifying the overall system architecture while maintaining reliability.
3Adaptability or versatility
If multiple sensors and controllers are integrated to monitor and activate safety devices, then functionality and safety monitoring are improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The electrical assembly merges multiple sensors and controllers into an integrated unit that performs both monitoring and activation functions. The controller receives signals from various sensors detecting crash conditions and directly activates the appropriate safety devices, reducing the number of separate components and simplifying manufacturing processes.

AI summary
An electrical assembly includes a support assembly and a track assembly. The support assembly may include a controller, a first safety device, and/or a second safety device. The track assembly may include a first tack and/or a second track. The support assembly may be configured for selective mechanical and/or electrical connection with the track assembly in a first direction and/or in a second direction. The controller may be configured to receive a first signal and/or a second signal from the track assembly. The controller may provide the first signal to the first safety device and/or provide the second signal to the second safety device when the support assembly is connected with the track assembly in the first direction and when the support assembly is connected with the track assembly in the second direction. The first safety device may include an airbag that may be activated by pyrotechnics.
