Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional reactors face challenges in size reduction and accurate temperature detection due to the need for space to accommodate temperature sensors between coils, which can lead to inaccurate temperature readings and potential sensor dislodgment.
Innovation Solution
A reactor design featuring a temperature sensor with a columnar detection portion inserted into a gap between a resin member and a coil, where the sensor is sandwiched by the resin member and coil for direct contact, utilizing a recess portion with an insertion guide and locking mechanism to ensure accurate positioning and secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a temperature sensor is arranged between the pair of coils, then temperature detection is enabled, but the reactor size increases due to required space for the sensor and holding member
Solution Approach 1:
The holding member for the temperature sensor is merged with the resin member that covers the core. The resin member simultaneously serves as both the structural covering component and the sensor mounting structure, eliminating the need for a separate holding member and reducing overall reactor volume.
Solution Approach 2:
The temperature sensor is extracted from the conventional between-coils positioning and relocated to the gap between the resin member and coil. This extraction allows the sensor to be integrated into the existing structural components without requiring additional space between the coil pairs.
2Reliability
If the temperature sensor is covered by a holding member, then the sensor is protected and positioned, but direct contact with the coil is prevented, resulting in inaccurate temperature detection
Solution Approach 1:
The resin member is designed with a localized recess portion that creates a specific region where the temperature sensor can make direct contact with the coil. This local modification allows the sensor to be exposed to the coil surface at the contact point while the rest of the sensor body remains protected within the resin member structure.
3Volume of moving object
If the temperature sensor is inserted between the resin member and coil, then size reduction is achieved and direct contact is enabled, but the sensor may fall off without proper securing
Solution Approach 1:
The resin member is pre-formed with a recess portion that includes an insertion guide and positioning features before the temperature sensor is installed. The insertion guide预先 provides the correct insertion path and depth, ensuring the sensor is automatically positioned correctly during installation, and the recess structure预先 prepares the mounting location to prevent sensor dislodgment.
