Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a heat storage material made of strongly correlated electron system material is used, then heat storage capacity is improved through electron phase transition, but thermal conductivity is insufficient leading to inefficient heat transfer
Solution Approach 1:
The patent combines strongly correlated electron system material (for heat storage) with high thermal conductivity material (for heat transfer) to form a composite heat storage unit. This composite structure allows the system to simultaneously achieve high heat storage capacity through electron phase transition and efficient heat transfer through the high conductivity material, resolving the contradiction between heat storage capacity and heat transfer efficiency.
2Use of energy by moving object
If heat storage material with electron phase transition is used, then latent heat storage is improved, but thermal conductivity remains insufficient
Solution Approach 1:
The patent creates a composite structure where strongly correlated electron system material provides latent heat storage through electron phase transition, while high thermal conductivity material ensures reliable heat transfer. The composite material approach allows both properties to coexist and function simultaneously.
Solution Approach 2:
The high thermal conductivity material acts as an intermediary between the heat transport medium and the electron phase transition material, facilitating efficient heat transfer to and from the heat storage material without interfering with the phase transition mechanism.
3Device complexity
If heat storage units are stationary, then system simplicity is maintained, but heat transfer efficiency decreases due to temperature difference variations
Solution Approach 1:
The patent introduces a rotating unit that dynamically switches the positions of heat storage units between different temperature zones. This dynamic configuration allows the system to maintain optimal temperature differences for heat transfer while managing the complexity through a relatively simple rotational mechanism.
Solution Approach 2:
The rotating unit performs periodic switching of heat storage unit positions, creating a cyclic pattern of heat absorption and release. This periodic action ensures continuous efficient heat transfer by regularly renewing the temperature difference between the heat storage units and the heat transport medium.

AI summary
A heat storage unit or a heat storage system is a heat storage unit (5) including: a heat storage portion (1) having a first material with a strongly correlated electron system material; and a heat conduction portion (3) having a second material higher in a thermal conductivity than the first material and being in contact with the heat storage portion. The heat storage unit may have a laminated structure in which the heat storage portion and the heat conduction portion are alternately laminated on each other. As the strongly correlated electron system material, for example, a metal-insulator phase transition material or a transition metal oxide may be used. The second material may be metal or ceramics. As a result, the heat of the heat transport medium can be efficiently stored.
