Robot Tray with Damper Stabilization to Reduce Liquid Food Overflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robots designed for everyday use are limited in their ability to provide a variety of services, and when carrying containers with liquid food, they often experience rapid acceleration and deceleration, leading to potential overflow of liquid food.
Innovation Solution
A tray design featuring a housing with a perimeter wall, a stabilizer with a moving body and dampers to absorb shock, and a top tray to cover the space, minimizing liquid food overflow and allowing for easy replacement of contaminated parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the robot accelerates and decelerates rapidly while carrying a container with liquid food on the tray, then the robot can travel efficiently and complete tasks quickly, but the liquid food may overflow from the container
Solution Approach 1:
The patent applies beforehand cushioning by introducing a damper between the tray and the robot body. This damper is installed in advance to cushion the shock and vibration generated during the robot's acceleration and deceleration, preventing liquid food from overflowing before the harmful motion occurs. The damper absorbs the impact forces, allowing the robot to maintain efficient travel while protecting the liquid food container.
2Reliability
If the tray structure is made more complex with additional components like dampers and stabilizers, then the overflow of liquid food can be minimized, but the device complexity increases
Solution Approach 1:
The patent uses an intermediary approach by introducing a damper as a mediating component between the robot body and the tray. This damper serves as a buffer that absorbs shock and vibration, reducing the direct transmission of harmful forces to the liquid food container. The intermediary damper simplifies the overall solution compared to more complex active control systems while effectively preventing overflow.
3Reliability
If the entire tray assembly is replaced when contaminated, then cleanliness can be maintained, but the loss of time and resources increases due to replacing functional parts
Solution Approach 1:
The patent applies segmentation by dividing the tray assembly into separable components: the tray body (which contacts food and may be contaminated) and the functional components (damper, stabilizer, etc. which remain clean). This allows only the contaminated tray body to be replaced while retaining the functional components, reducing replacement time and resource waste while maintaining cleanliness standards.
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 tray effectively reduces liquid food overflow, maintains cleanliness, and allows for deceleration of the tray, minimizing noise and abrasion, while enabling the top tray to be replaced independently.
Implementation Method 1
The dampers may include elastic members, cross-sections of which have closed loop shapes
Implementation Method 2
a plurality of dampers disposed between an edge of the moving body and the perimeter wall
Implementation Method 3
The spiral spring may include: an outer circumference fitted to the lower plate; a central portion spaced apart from the outer circumference and provided with a hole through which a fastening member fastened to the moving body passes; and a bridge connecting the outer circumference and the central portion and having a spiral shape
