Solution Overview

Problem

There is a lack of technology for actively heating or cooling dishwasher-safe dishware and drinkware, which limits the ability to maintain food at desired temperatures for extended periods.

Innovation Solution

The development of dishwasher-safe dishware and drinkware equipped with a heating or cooling system that includes a heating or cooling element, power storage, and a wireless power receiver, allowing for wireless charging and controlled temperature maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If passive heating or cooling mechanisms are used in ceramic dishware, then the dishware can maintain food temperature for a longer time, but the heating or cooling effect is limited and cannot be actively controlled

Engineering Contradiction:
Improvetemperature maintenance durationVSAvoidactive temperature control
Core Design Contradiction:
Duration of action of moving objectVSEase of operation

Solution Approach 1:

The patent replaces passive thermal mechanisms with an active electrical heating system. A heating element powered by a rechargeable battery provides controllable heat to the dishware, while a wireless power receiver enables convenient recharging without physical connections. This substitution transforms the system from passive thermal retention to active, user-controllable temperature maintenance.

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

2Ease of operation

If heating or cooling elements are integrated into dishwasher-safe dishware, then active temperature control is achieved, but the heating components may be damaged by water exposure

Engineering Contradiction:
Improveactive heating capabilityVSAvoidheating component durability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent extracts the heating element and battery from direct contact with water by positioning them in isolated compartments within the dishware structure. The heating element is mounted on the underside of the dishware body, separated from the food-containing cavity. This extraction allows the dishware to be dishwasher-safe while maintaining active heating functionality, as the electrical components never encounter water during normal use or cleaning.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a wireless power receiver as an intermediary between the power source and the heating element. This wireless charging mechanism eliminates the need for physical electrical connections that would be vulnerable to water damage. The power transfer occurs through electromagnetic fields without direct contact, protecting the electrical interface from water exposure while enabling battery recharging.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Duration of action of moving object

If wireless power receiver and power storage elements are added to dishware, then extended temperature maintenance is enabled, but the device complexity increases

Engineering Contradiction:
Improvetemperature maintenance durationVSAvoidsystem component count
Core Design Contradiction:
Duration of action of moving objectVSDevice complexity

Solution Approach 1:

The patent merges multiple functions into integrated components. The battery serves dual purposes as both power storage for the heating element and as a structural element within the dishware assembly. The wireless power receiver is combined with the battery housing, creating a unified power management module. This merging reduces the number of separate components and simplifies the overall system architecture while maintaining extended temperature maintenance capability.

Inventive Principle:
Principle #5Merging (Combining)
