Solution Overview

Problem

Traditional shelving systems in retail environments face issues where products on lower shelves are obscured by higher shelves, leading to reduced visibility and sales, and stacking solutions can cause product damage and feeding problems.

Innovation Solution

A shelving system with stowable shelves that utilize a mechanism of longitudinal openings and actuated extensions within channels, allowing vertical movement of shelves upon actuation, which enables them to retract and expose lower shelves when products are removed, thereby increasing visibility and preventing blockage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If products are placed on higher shelves, then more display space is utilized, but visibility to products on lower shelves is blocked

Engineering Contradiction:
Improvedisplay space utilizationVSAvoidproduct visibility
Core Design Contradiction:
Quantity of substanceVSLoss of information

Solution Approach 1:

The shelf system employs dynamic, movable shelves that can automatically change their vertical position based on product presence. When products are removed from a shelf, the shelf automatically rises to fill the gap, maintaining optimal display space utilization while ensuring lower shelves remain visible to customers.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The shelving system uses sensors to detect when products are removed and automatically actuates the shelves to move into position without human intervention. This self-service mechanism ensures continuous visibility to lower shelf products while maximizing display capacity.

Inventive Principle:
Principle #25Self-service

2Loss of information

If shelves are made stowable with vertical movement capability, then visibility to lower shelves is improved, but device complexity increases

Engineering Contradiction:
Improveproduct visibilityVSAvoidshelving mechanism complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The system uses product presence sensors to automatically trigger shelf movement mechanisms. When sensors detect that products have been removed from a shelf, they automatically actuate the hydraulic or pneumatic cylinders to move the shelf vertically, eliminating the need for manual adjustment while maintaining simple operation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces complex manual mechanical adjustment systems with automated hydraulic or pneumatic cylinder mechanisms controlled by sensors. This substitution simplifies the user interaction while providing smooth, controlled vertical movement of shelves to maintain visibility.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Quantity of substance

If traditional stacking solutions are used to manage product space, then shelf space is optimized, but product damage risk increases

Engineering Contradiction:
Improveshelf space optimizationVSAvoidproduct integrity
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

Instead of static stacking arrangements that can cause product damage, the system uses dynamic shelves that automatically adjust their height. When products are removed, the shelves rise smoothly to fill the space, maintaining optimal shelf space utilization while keeping products in their original positions without stacking, thus preventing product damage.

Inventive Principle:
Principle #15Dynamics
