Porter Module Baggage Holding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robots for everyday use are limited in their ability to provide a wide range of services and lack the capability to stably support and transport baggage without causing damage to the baggage or surrounding objects.
Innovation Solution
A porter module with a main body, left and right pressing bodies, and an adjusting mechanism that includes motors, cams, and pullers to securely hold and transport baggage, minimizing damage by adjusting the interval between pressing bodies and using sensors for control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If pressing bodies are used to hold baggage, then stability of baggage transport is improved, but risk of damage to baggage increases
Solution Approach 1:
The pressing bodies are made movable relative to each other through the adjusting mechanism, allowing dynamic adjustment of the holding force. The interval between pressing bodies can be changed to adapt to different baggage sizes and weights, optimizing both stability and damage prevention.
Solution Approach 2:
The adjusting mechanism changes the physical parameter of interval between pressing bodies based on detected baggage characteristics. By varying this spatial parameter, the system adapts the pressing force distribution to match the baggage's center of gravity and dimensions.
2Device complexity
If fixed interval between pressing bodies is used, then device complexity is reduced, but adaptability to different baggage types decreases
Solution Approach 1:
The adjusting mechanism introduces dynamic adjustability to the pressing body arrangement. Motors and cams enable the pressing bodies to move to optimal positions for different baggage types, transforming a static system into a dynamic one.
Solution Approach 2:
The system uses sensors to automatically detect baggage characteristics and triggers the adjusting mechanism to self-adjust the pressing body interval without manual intervention, enabling autonomous adaptation to different cargo.
3Stability of the object's composition
If pressing bodies are moved closer together, then baggage holding stability is improved, but difficulty of servicing and release increases
Solution Approach 1:
The pressing mechanism is divided into separate movable pressing bodies that can be independently adjusted and serviced. The adjusting mechanism allows each pressing body to be accessed and maintained separately while maintaining the overall structural integrity during operation.

AI summary
A porter module includes: a main body having a space formed between a left body and a right body spaced apart from each other in a left-right direction; a left pressing body disposed on the left body; a right pressing body disposed on the right body and disposed to face the left pressing body; and an adjusting mechanism installed in the main body and moving at least one of the left pressing body and the right pressing body to adjust an interval between the left pressing body and the right pressing body.
