Solution Overview

Problem

Delicately presented food or drinks tend to collapse or spill due to acceleration or deceleration during transportation, posing safety concerns.

Innovation Solution

A control device that manages the movement of a transporting unit connected to a moving unit, featuring a first control unit for chassis speed and a second control unit for the mounting table to adjust its speed and acceleration independently, ensuring the transportation target is securely moved by synchronizing the movement of the chassis and mounting table.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If the moving unit (chassis) accelerates or decelerates during transportation, then the transportation efficiency and speed are improved, but the transportation target (delicately presented food or drink) may collapse or spill due to the acceleration forces

Engineering Contradiction:
Improvetransportation speedVSAvoidsafety of transportation target
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The transportation system is divided into two independent control units: the moving unit (chassis) and the transporting unit (mounting table). This segmentation allows each unit to be controlled independently, enabling the chassis to move at higher speeds while the mounting table maintains stability to protect delicate transportation targets from acceleration forces.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic control where the transporting unit adjusts its movement based on the acceleration and deceleration states of the moving unit. By detecting the movement state of the chassis and dynamically adjusting the mounting table's position and speed, the system maintains stability of the transportation target during speed changes.

Inventive Principle:
Principle #15Dynamics

2Stability of the object's composition

If the transporting unit moves independently to compensate for acceleration, then the stability of the transportation target is improved, but the control system complexity increases

Engineering Contradiction:
Improvestability of transportation targetVSAvoidcontrol system complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The control system employs feedback mechanisms where the movement state of the chassis is detected and used to adjust the transporting unit's movement. This feedback loop enables the mounting table to compensate for acceleration forces automatically, maintaining transportation target stability while using a relatively simple control architecture.

Inventive Principle:
Principle #23Feedback
