Spaced-Apart Screen Units on Shopping Trolleys
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shopping carts do not effectively influence purchasing behavior, as they typically have a single screen or screens arranged centrally, limiting the shopper's field of view and not encouraging increased purchases.
Innovation Solution
Equipping a shopping cart with at least two spaced-apart screen units, arranged to the sides or along its length, to present information in a decentralized manner, forcing the shopper to expand their field of view and increasing exposure to products or promotional offers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single screen or centrally arranged screens are used, then the device complexity is reduced, but the purchasing behavior influence is limited
Solution Approach 1:
The screen is divided into multiple separate screen units (at least two) that are spaced apart from each other. This segmentation forces the shopper to move their gaze across different locations, effectively widening their field of view and increasing exposure to various products and promotional information, thereby enhancing purchasing behavior influence without requiring a single complex large screen.
2Area of moving object
If screens are arranged close to one another, then the device complexity is reduced, but the field of view is not sufficiently widened
Solution Approach 1:
Instead of arranging screens closely together in a compact manner, the invention spaces the screen units apart by 10-70 cm, utilizing the longitudinal dimension of the shopping cart. This dimensional arrangement creates a more extensive visual spread along the shopping path, forcing the shopper to scan across a larger area and effectively widening their field of view.
3Productivity
If information is presented in the center of the field of view, then the information is easily noticed, but the purchasing behavior influence is reduced
Solution Approach 1:
Instead of concentrating information in the center of the field of view where it is most easily noticed, the invention deliberately places screen units at spaced-apart locations that require the shopper to move their gaze away from the center. This inverted approach ensures that information is distributed across multiple locations, preventing the shopper from focusing on a single central area and thereby enhancing overall purchasing behavior influence.
