Solution Overview
Problem
Existing driving robots for daily use face challenges with complex assembly and disassembly, difficult maintenance, and inefficient space utilization, particularly when transporting food, which can lead to spills and malfunctions due to collisions with obstacles.
Innovation Solution
A driving robot design featuring a lower housing with a frame assembly, a battery, and a substrate module, where the frame assembly includes a base plate, side frames, and a front frame, allowing easy removal and assembly of components like the substrate module and battery, with a caster housing for stable suspension and open rear access for maintenance, and a tray frame for efficient space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the robot uses a fixed integrated structure for housing and components, then structural stability is improved, but maintenance difficulty increases and assembly/disassembly becomes complex
Solution Approach 1:
The robot body is divided into modular components including a lower housing, frame assembly, substrate module, and battery module. Each component can be independently accessed, removed, or replaced through the open rear surface design, enabling easy maintenance while maintaining structural integrity during operation.
2Volume of moving object
If the robot uses a compact integrated design, then space utilization is improved, but assembly/disassembly complexity increases
Solution Approach 1:
The robot employs a modular architecture where the substrate module and battery are separate replaceable units within the frame assembly. The open rear surface allows these modules to be accessed and replaced without disassembling the entire robot, achieving compact design with simplified maintenance.
Solution Approach 2:
The frame assembly serves multiple functions: it provides structural support, houses the battery and substrate module, and enables easy access to components through its open rear design. This multi-functional design optimizes space while simplifying assembly and disassembly operations.
3Reliability
If the robot uses traditional closed housing design, then protection of internal components is improved, but access to electronic components for maintenance becomes difficult
Solution Approach 1:
The housing is designed with an open rear surface that provides direct access to the frame assembly, substrate module, and battery. This segmented design allows maintenance personnel to access electronic components without opening the entire housing, maintaining component protection while improving accessibility.

AI summary
A driving robot comprises: a lower housing; a frame assembly disposed within the lower housing; a driving unit disposed under the frame assembly; a battery seated in the frame assembly; and a substrate module coupled to the frame assembly and disposed over the battery, wherein the frame assembly comprises: a base plate; a pair of side frames disposed on both left and right sides of the battery; and a front frame disposed at the front of the frame assembly and connected to the pair of side frames. The driving robot is open in the direction of the rear of the frame assembly in which electronic components are mounted, and thus has an advantage of easy maintenance.
