Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fixed-type objects with wheels face challenges in navigation due to wheel damage from heavy loads and difficulty in manual movement, even with wheels installed.
Innovation Solution
An electronic device attached to fixed-type objects that records a moving path using a light emitting element and optical sensor, and moves based on this path, with separate wheels for recording and traveling to minimize damage and ensure accurate navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wheels are provided on fixed-type objects to allow easy movement, then ease of operation is improved, but wheel damage occurs due to heavy weight and function degradation
Solution Approach 1:
The patent divides the wheel system into two separate functions: a recording wheel that rotates passively to record movement paths and a traveling wheel that is driven by a motor to execute movements. This segmentation allows the recording wheel to be lightweight and not bear the full load, while the traveling wheel handles the driving force, thereby reducing wheel damage and improving reliability
Solution Approach 2:
The patent replaces manual mechanical pushing with an automated motor-driven traveling wheel system. The controller receives commands from a terminal device and automatically controls the traveling wheel to move the object, eliminating the need for continuous manual force and reducing mechanical stress on the wheel structure
2Ease of operation
If wheels are provided on fixed-type objects to allow easy movement, then ease of operation is improved, but difficulty in navigation remains due to heavy weight
Solution Approach 1:
The patent implements a recording wheel that pre-records the desired movement path by rotating in response to manual pushing or terminal device commands. This recorded path is stored in memory and later replayed by the traveling wheel, allowing complex navigation to be simplified into a record-and-replay process that reduces navigation complexity
Solution Approach 2:
The patent creates a copy of the movement path through the recording wheel's rotation pattern, which is stored as digital data. This copied path information is then used to control the traveling wheel, replacing complex real-time navigation calculations with simple path following, thereby reducing device complexity
3Reliability
If separate wheels for recording and traveling are used, then wheel damage is minimized, but device complexity increases
Solution Approach 1:
The patent designs the recording wheel to serve multiple functions: it records movement paths by rotating, and its rotation pattern is used to control the traveling wheel. This multi-functionality reduces the need for separate complex recording mechanisms, thereby minimizing wheel damage while controlling device complexity

AI summary
An electronic device having a moving part is provided. The electronic device includes a moving part; a light emitting element; an optical sensor; a memory; a communication interface; and a controller configured to: based on the electronic device moving and being in a recording mode, output light from the light emitting element; receive the light reflected from a ground by the optical sensor; acquire information about a moving path of the electronic device based on the received light and store the information in the memory; and based on receiving a control signal for moving the electronic device along the moving path from a user terminal device through the communication interface, set an operation mode of the electronic device as a travel mode, and control the moving part so that the electronic device moves along the moving path.
