Solution Overview

Problem

Service technicians face challenges when accessing and servicing built-in induction ranges, as they often need to cut out and re-install the top piece from the countertop, requiring skilled handling of adhesives which can lead to poor quality work and refusal to reapply adhesives in some cases.

Innovation Solution

A temperature-regulating appliance design featuring a detachable base and top portion with a mounting adapter, allowing for easy access and removal of the base without breaking the connection or watertight seal, using a mounting adapter to securely couple the base to the top portion, and incorporating a temperature sensor that remains with the base during detachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the top piece is permanently installed using adhesive product, then the seal preventing water migration is improved, but the ease of servicing the base deteriorates

Engineering Contradiction:
Improveseal integrityVSAvoidbase accessibility
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The appliance is divided into separable components: the top piece remains permanently sealed to the countertop, while the base is segmented into a removable module that can be detached without affecting the seal. The mounting adapter creates a mechanical connection between the top piece and base that allows base removal while preserving the adhesive bond between top piece and countertop.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A mounting adapter is introduced as an intermediary component between the top piece and the base. This adapter provides a mechanical coupling mechanism that enables easy base removal while maintaining the permanent adhesive seal between the top piece and countertop, thus resolving the contradiction between seal integrity and serviceability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If service technicians reapply adhesive product during servicing, then the seal is restored, but the quality of work deteriorates due to lack of skill

Engineering Contradiction:
Improveseal restorationVSAvoidinstallation quality
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The base is extracted as a separate, removable component that does not require adhesive reapplication during servicing. Only the top piece remains permanently bonded to the countertop, eliminating the need for technicians to handle adhesives during routine base maintenance or replacement.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The mounting adapter serves as a mediator that eliminates the need for adhesive reapplication during base servicing. It provides a mechanical interface that allows the base to be removed and reinstalled without disturbing the permanent seal between the top piece and countertop.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stability of the object's composition

If the base is permanently mounted, then the structural stability is improved, but the productivity of servicing deteriorates

Engineering Contradiction:
Improvestructural stabilityVSAvoidservicing speed
Core Design Contradiction:
Stability of the object's compositionVSProductivity

Solution Approach 1:

The appliance structure is segmented into a permanently mounted top piece (providing stability) and a removable base (enabling quick servicing). The mounting adapter creates a stable yet detachable connection, allowing the base to be rapidly removed and replaced without compromising the overall structural integrity during normal operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting system transitions from a static permanent bond to a dynamic removable connection for the base. The mounting adapter enables the base to be easily detached and reattached, transforming the servicing process from a complex permanent installation to a simple plug-and-play operation, thereby dramatically improving servicing productivity.

Inventive Principle:
Principle #15Dynamics

AI summary

A temperature-regulating appliance includes a top portion, a base, a temperature sensor, and a mounting adapter. The top portion has an upper surface and a lower surface. The base includes a housing defining an internal compartment and a thermal element disposed within the internal compartment of the housing. The temperature sensor is positioned outside of the internal compartment, between the housing and the lower surface of the top portion. The mounting adapter extends between the top portion and the housing. The mounting adapter detachably couples the base to the top portion.
