Removable Shopping Bag With Integrated Scale For Self-Service Trolley
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shopping trolleys with integrated baskets and functional modules do not allow customers to easily place selected goods into shopping bags for direct removal from the shopping area, requiring additional handling and contact with the goods.
Innovation Solution
A shopping trolley design featuring a frame with a built-in scale and electronic control device, allowing for autonomous scanning and weighing, with a removable shopping bag that can be taken home, minimizing contact with the goods and enabling self-service shopping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional shopping trolleys with integrated baskets are used, then goods can be stored during shopping, but customers cannot easily place selected goods into shopping bags for direct removal
Solution Approach 1:
The trolley is divided into separate functional components: a frame construction with wheels and an electronic control device, and a removable shopping bag. This segmentation allows the shopping bag to be detached and taken away independently, enabling customers to place selected goods directly into the bag for removal without handling integrated baskets.
Solution Approach 2:
The shopping bag is designed to be dynamically removable from the frame construction, transitioning from a fixed integrated basket configuration to a detachable bag system. This dynamic reconfiguration enables flexible operation where the bag can be attached during shopping and removed for direct takeaway of purchased goods.
2Ease of operation
If conventional shopping trolleys require cash checkout stations, then payment transactions can be completed, but customer contact with goods increases during unloading and repacking
Solution Approach 1:
The trolley is equipped with an electronic control device that enables self-service shopping functions including autonomous scanning, recognition and weighing of goods, and processing of payment transactions. This automation allows customers to complete the entire shopping process independently without staff assistance, minimizing contact with goods to only placing them in the shopping bag.
Solution Approach 2:
The electronic control device integrates multiple functions into a single system: scanning goods, weighing products, processing payments, and providing customer identification. This multi-functional integration enables autonomous shopping capability, allowing the trolley to serve as both a transport device and a complete checkout system.
3Adaptability or versatility
If shopping baskets are fixed in the frame construction, then goods can be stored, but the trolley cannot accommodate removable shopping bags for direct takeaway
Solution Approach 1:
The storage function is segmented from the frame construction by using a separate removable shopping bag instead of fixed integrated baskets. This allows the bag to be detached and taken away with purchased goods, providing adaptability while keeping the frame construction relatively simple with only wheel and suspension assemblies.
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
Simplifies the shopping process by allowing customers to place products directly into a shopping bag for home removal, reducing contact with goods and enhancing autonomous shopping capabilities.
Implementation Method 1
the scale is positioned above the wheels and suspension assembly... the shopping bag is seated with its bottom on the surface of the scale

AI summary
A shopping trolley for self-service shopping, includes a frame (1) supported by wheels (51, 52) The frame includes longitudinal beams (2) which at an upper end portion are coupled to each other by a handrail (3) that extends transverse thereto. A suspension assembly (4) extends operatively intermediate of the wheels and the frame. A scale (7) that includes an upward facing weighing surface is operatively supported by the frame. The shopping trolley includes a removable shopping bag (9) with a bottom (91). A pair of releasable grips (8) are operable to secure the shopping bag in a position with its bottom (91) on the weighing surface of the scale. An electronic terminal (6) is in operative connection with the scale.
