Motorized Shopping Cart With Adjustable Mobile Carrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shopping carts require manual effort to push or pull, especially for elderly or weak consumers, and are difficult to maneuver on inclines.
Innovation Solution
A rechargeable, motorized personal shopping cart with a base frame and an adjustable mobile carrier that can propel itself on request, allowing for easy movement of containers both straight and sideways.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a manual shopping cart is used, then the cart structure is simple and lightweight, but it requires manual effort to push or pull which exceeds the ability of elderly or weak consumers
Solution Approach 1:
The patent replaces the manual mechanical propulsion system with an electric motor system. The motorized cart uses an electric motor to provide propulsion force, eliminating the need for manual pushing or pulling. This substitution directly resolves the contradiction by improving ease of operation for elderly or weak consumers while accepting increased device complexity through the addition of motor, battery, and control components.
2Adaptability or versatility
If a fixed-height carrier is used, then the cart structure is simple, but it cannot accommodate different container sizes or user height requirements
Solution Approach 1:
The patent applies the dynamics principle by making the carrier height adjustable rather than fixed. The mobile carrier can be positioned at different heights along the upright tubes, allowing adaptation to various container sizes and user preferences. This dynamic adjustment capability resolves the contradiction by improving versatility while managing complexity through a straightforward mechanical adjustment mechanism.
Solution Approach 2:
The patent segments the carrier structure into multiple adjustable positions along the upright tubes. The carrier can be detached and repositioned at different height levels, creating modular adaptability. This segmentation approach enables the single carrier to serve multiple functions and accommodate different requirements without requiring multiple fixed-height carriers.
3Quantity of substance
If a single fixed carrier is used, then the cart structure is simple, but it cannot maximize cargo capacity or provide flexible loading options
Solution Approach 1:
The patent merges the functionality of multiple carriers into a single mobile carrier system. The mobile carrier can hold multiple containers simultaneously and can be positioned to optimize cargo distribution. This merging approach maximizes cargo capacity while avoiding the complexity of managing entirely separate fixed carriers, as the mobile carrier integrates storage and transport functions.
