Solution Overview

Problem

Current plastic bins used for online grocery orders lack temperature control, limiting the time and distance that refrigerated or frozen items can be stored, which poses logistical challenges for retailers.

Innovation Solution

Condition-controlled totes equipped with refrigeration units and communication capabilities to receive commands for maintaining temperature, entering a refrigeration state, or entering a freezer state, are used to manage online grocery orders.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of stationary object

If plastic bins are used for holding grocery items, then the items can be stored and transported, but the time and distance for storing refrigerated and frozen items is limited due to lack of temperature control

Engineering Contradiction:
Improvestorage timeVSAvoidtemperature control
Core Design Contradiction:
Duration of action of stationary objectVSReliability

Solution Approach 1:

The patent applies parameter changes by transitioning from passive plastic bins to active temperature-controlled totes. The totes incorporate refrigeration units that can dynamically adjust temperature parameters to maintain refrigerated and frozen conditions throughout the supply chain, thereby extending storage time while ensuring temperature reliability.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The totes are designed with self-service temperature control capabilities through integrated refrigeration units. These units autonomously maintain required temperature levels without external intervention, allowing the totes to self-regulate their thermal environment during transport and storage, thus extending usable duration while maintaining reliability.

Inventive Principle:
Principle #25Self-service

2Length of moving object

If plastic bins are used for holding grocery items, then the items can be stored, but the delivery distance is limited due to lack of temperature control

Engineering Contradiction:
Improvedelivery distanceVSAvoidtemperature control
Core Design Contradiction:
Length of moving objectVSReliability

Solution Approach 1:

The patent implements parameter changes by equipping totes with active refrigeration systems that can maintain temperature parameters over extended periods. This enables the totes to sustain refrigerated and frozen conditions during longer transit times and greater distances, thereby expanding delivery radius while ensuring temperature reliability throughout the journey.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The refrigeration units within the totes provide self-service temperature management during transport. These autonomous systems continuously monitor and adjust temperature levels without external input, allowing the totes to independently maintain proper conditions over extended delivery distances, thus resolving the contradiction between distance and reliability.

Inventive Principle:
Principle #25Self-service

3Reliability

If condition-controlled totes with refrigeration units are used, then temperature control and extended storage are achieved, but device complexity increases

Engineering Contradiction:
Improvetemperature controlVSAvoidtote structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies universality by designing multi-functional totes that combine storage, temperature control, tracking, and communication capabilities in a single integrated system. The totes serve multiple functions simultaneously - holding groceries, regulating temperature, monitoring location, and communicating with the fulfillment system - thereby managing complexity through functional integration rather than adding separate systems.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges multiple functions into the tote structure itself. The refrigeration unit, temperature sensors, communication modules, and tracking devices are integrated directly into the tote housing, creating a unified temperature-controlled smart container. This merging approach consolidates complexity within a single coordinated system rather than requiring separate independent components.

Inventive Principle:
Principle #5Merging (Combining)
