Solution Overview
Problem
Existing kitchen utensils for induction hobs often suffer from uneven temperature distribution and require specialized hobs, which can limit their versatility and compatibility with sensitive surfaces, while also potentially damaging the induction coil and worktops due to excessive heat.
Innovation Solution
A kitchen utensil design featuring an inner and outer shell with partial wireless or wired electrical connections, allowing for selective electrical component activation and thermal insulation, enabling operation on standard induction hobs without damaging the coil or worktops, and allowing for modular design and easy adaptation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the inner shell is directly heated by induction coil, then heating efficiency is improved, but the outer shell temperature becomes excessively high causing damage to induction coil and worktops
Solution Approach 1:
The cooking vessel is divided into an inner shell and an outer shell separated by a gap. The inner shell is directly heated by the induction coil for efficient heating, while the outer shell remains thermally isolated to prevent excessive temperature and protect the induction coil and worktop surfaces.
Solution Approach 2:
The gap between the inner shell and outer shell acts as a thermal barrier and intermediary space. This gap prevents direct heat transfer from the heated inner shell to the outer shell, maintaining the outer shell at safe temperatures while allowing the inner shell to reach cooking temperatures efficiently.
2Temperature
If thermal insulation material is added between inner and outer shells, then outer shell temperature is reduced, but device complexity increases
Solution Approach 1:
The patent utilizes the existing gap space between inner and outer shells as a simple, cost-effective thermal insulation solution. Instead of adding complex insulation materials or structures, the design leverages the natural air gap as a thermal barrier, maintaining simplicity while achieving temperature control.
3Measurement precision
If electrical components are added to both inner and outer shells, then functionality and measurement accuracy are improved, but device complexity increases
Solution Approach 1:
Electrical components such as temperature sensors and communication modules are integrated into both the inner shell and outer shell, allowing them to serve multiple functions: monitoring temperature at different locations, providing redundant measurement capability, enabling wireless communication, and supporting various operating modes. This multi-functionality justifies the added complexity by significantly improving measurement accuracy and operational flexibility.
