Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robots for everyday life are limited to specific services and have high technical difficulty and manufacturing costs due to individual structures for different purposes, and they often experience instability and shaking during travel.
Innovation Solution
A robot design featuring a base with downward protruding driving wheels, upward-extending lower pillars, and a suspension system on these pillars, allowing the driving wheel to move between positions, with a spring mechanism and a suspension arm that minimizes interference and secures a long stroke, supported by symmetrically placed pillars for stable load distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a robot is designed with individual structures for different service types, then it can provide specific services, but the technical difficulty and manufacturing costs increase
Solution Approach 1:
The patent applies universality by designing a common mobile body structure that can be used across different robot types. The base, driving wheels, lower pillars, and suspension system form a standardized platform that supports various upper modules for different services (e.g., cleaning, delivery, surveillance), eliminating the need to redesign the entire robot for each service type
Solution Approach 2:
The robot is segmented into distinct functional modules: a standardized mobile body (base with suspension and driving wheels) and interchangeable upper modules specific to each service. This segmentation allows the common mobile body to be developed once and reused, while only the service-specific upper modules need to be designed and manufactured for each application
2Productivity
If conventional robots are designed for specific services, then they can perform dedicated tasks, but utilization is not high compared to development costs
Solution Approach 1:
By creating a universal mobile body platform, the patent enables high utilization rates as the same base structure can serve multiple different services. The standardized design reduces per-unit manufacturing costs through economies of scale, while the interchangeable upper modules allow flexible adaptation to different service requirements, improving overall productivity and cost-effectiveness
3Adaptability or versatility
If a robot travels on uneven terrain, then it can navigate various environments, but shaking and instability occur
Solution Approach 1:
The patent implements dynamics through the suspension system that allows the driving wheels to move independently relative to the base. The suspension arms and sliders enable the wheels to adapt to uneven terrain by moving up and down, while the spring mechanisms provide dynamic cushioning to absorb shocks and reduce vibrations, maintaining stability during travel across various surfaces
4Stability of the object's composition
If a suspension system is added to reduce shaking, then travel stability improves, but device complexity increases
Solution Approach 1:
The suspension system applies local quality by implementing damping and cushioning functions at specific locations where driving wheels connect to the base. Rather than making the entire robot structure complex, the suspension components (sliders, springs, suspension arms) are localized to the wheel assembly areas, providing stability improvement with minimal impact on overall structural simplicity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enables versatile application across various services, reduces vibration, stabilizes travel, and lowers manufacturing costs by simplifying the structure and distributing load effectively, allowing the robot to navigate uneven terrain with minimal shaking.

AI summary
A robot includes a base, a driving wheel protruding downward from the base, a plurality of lower pillars extending upward from the base, an upper module supported by the plurality of lower pillars, and a suspension coupled to at least one lower pillar of the plurality of lower pillars and being coupled to the driving wheel. The suspension may include a slider configured to move upward and downward while sliding along the at least one lower pillar, a spring disposed relative to an outer circumference of the lower pillar and being positioned to provide a force that causes the slider to move downward, a suspension arm coupled to the slider and a rotational shaft of the driving wheel, a connector coupled to the base, and a rotational shaft of the suspension arm being coupled to the connector.
