Insulation System for Ground Mobile Robots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current last-mile delivery methods, particularly for food items, face challenges in maintaining temperature integrity due to the lack of effective insulation systems in ground-based mobile robots, which can lead to food items becoming cold or spoiled during delivery.
Innovation Solution
An insulation system for ground-based mobile robots comprising a container with a thermal shield and U-brackets, secured by fasteners, made from high-temperature resistant materials like polycarbonate and ABS thermoformed plastic, designed to retain heat and keep electronic components separate from the food storage area, with a locking mechanism for secure delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If ground-based mobile robots are used for last-mile deliveries, then carbon emissions and traffic congestion are reduced, but temperature control of food items during delivery deteriorates
Solution Approach 1:
The robot's cargo area is segmented into two distinct zones: a thermally insulated bag for food items and a heated compartment for electronic components. This segmentation allows the food storage area to maintain temperature control while the electronic components can operate at higher temperatures without affecting the food.
Solution Approach 2:
A thermal shield acts as an intermediary barrier between the heated electronic components and the food storage bag. This thermal shield prevents heat transfer from the electronic components to the food, allowing both to coexist in the same cargo space while maintaining their respective temperature requirements.
2Device complexity
If electronic components are placed in the cargo area, then device complexity is reduced, but heat generation from components causes temperature increase in food storage area
Solution Approach 1:
The cargo area is divided into a food storage bag and a separate compartment for electronic components. This physical segmentation allows electronic components to be placed in the cargo area without compromising food temperature control.
Solution Approach 2:
A thermal shield serves as a heat-blocking intermediary between the electronic components and the food storage area, enabling the integration of electronic components in the cargo space while preventing their heat from affecting the food.
3Ease of operation
If a simple open cargo area is used, then ease of loading and unloading is improved, but temperature preservation of food items is compromised
Solution Approach 1:
A flexible insulated bag with an opening is used for food storage. The opening allows easy loading and unloading of food items while the insulated material maintains temperature control. The bag can be easily accessed and opened without requiring complex mechanisms.

AI summary
An insulation system for a mobile delivery robot including a container and a thermal shield. The thermal shield is coupled to the bottom of the container to provide a thermal barrier between the contents of the container and the components of the mobile robot. The container further includes components to organize food products including drink holders and a plurality of supports for supporting food boxes, such as a pizza box.
