Vehicle Temporary Mobility Kit Status Indicator System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Temporary mobility kits, which replace traditional spare tires in vehicles, are often overlooked during maintenance due to their concealed location, leading to potential sealant degradation over time, especially under varying temperature conditions, necessitating a reminder system for vehicle operators to service them.
Innovation Solution
A status indicator and reminder system integrated into the vehicle's instrument panel, featuring a timer, temperature sensor, and controller to generate service warnings based on the kit's age and environmental conditions, with a feedback mechanism to notify operators of necessary servicing and re-set functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the temporary mobility kit is concealed in the vehicle (e.g., in the spare tire well), then vehicle weight is reduced and styling is improved, but the kit is overlooked during maintenance and sealant degradation occurs over time
Solution Approach 1:
The patent implements a reminder system with a controller that generates service warning signals based on timer signals tracking the kit's age and temperature sensor data monitoring environmental conditions. This feedback mechanism notifies the operator when servicing is needed, resolving the maintenance oversight issue while keeping the kit concealed.
Solution Approach 2:
The system automatically monitors the temporary mobility kit's status without requiring manual intervention. The timer and temperature sensor continuously track conditions, and the controller autonomously generates warnings, allowing the system to self-monitor and alert the operator rather than requiring regular manual checks.
2Duration of action of moving object
If the temporary mobility kit is stored in the vehicle for extended periods, then it provides continuous availability, but sealant degradation occurs due to temperature variations and time passage
Solution Approach 1:
The system performs preliminary monitoring of time and temperature conditions to predict when sealant degradation may occur. By tracking the kit's age and environmental exposure before actual degradation happens, the system can alert the operator to service the kit proactively, maintaining sealant effectiveness throughout the storage period.
Solution Approach 2:
The system monitors changes in critical parameters (time duration and temperature) that affect sealant degradation. By tracking these parameter changes, the controller can determine when servicing is needed based on accumulated time and temperature exposure, ensuring the sealant remains effective throughout the kit's service life.
3Reliability
If a reminder system with timer and temperature sensor is added to the temporary mobility kit, then maintenance timing is improved, but device complexity increases
Solution Approach 1:
The patent combines the timer, temperature sensor, and controller into an integrated reminder system that works together as a single unit. This merging of components reduces overall system complexity compared to having separate independent systems, while still providing accurate maintenance timing based on both time and temperature data.
Solution Approach 2:
The controller serves multiple functions: it processes timer signals, analyzes temperature data, determines when servicing is needed, and generates warning signals. This multi-functionality reduces the need for separate dedicated components for each task, thereby reducing overall system complexity while maintaining reliable maintenance timing.

AI summary
A status indicator and reminder system for use with a vehicle having a tire sealant-containing temporary mobility kit is provided. The system includes a signal provided for viewing by the operator which indicates that the temporary mobility kit requires servicing. The need for servicing can be based on certain variables, including the passage of a pre-determined period of time or on changes in temperature which may impact the effective life of the sealing compound. In addition, the need for servicing can be based on a sensed of the temporary mobility kit from the vehicle.
