Solution Overview

Problem

Conventional reactors face challenges in panel-mounting when the securing notches are perpendicular to the direction of gravity, requiring more time and effort due to wiring limitations, especially for larger or heavier reactors.

Innovation Solution

A reactor design featuring a polygonal base with notches on non-opposite sides to allow for flexible orientation and secure fastening, enabling temporary securing regardless of the notch direction relative to gravity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If securing notches are formed in the base in the same directions as drawing directions of cables (conventional design), then the reactor can be temporarily secured when mounted with notches parallel to gravity direction, but the reactor cannot be temporarily secured when mounted with notches perpendicular to gravity direction due to wiring limitations

Engineering Contradiction:
Improvemounting orientation flexibilityVSAvoidtemporary securing capability
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The base is divided into multiple sides with different notch configurations. Specifically, a first side has notches extending in a first direction while a second side has notches extending in a second direction different from the first direction. This segmentation allows the reactor to be mounted in different orientations depending on wiring requirements, enabling temporary securing in various mounting positions without being constrained by a single notch orientation.

Inventive Principle:
Principle #1Segmentation

2Power

If the reactor is larger in size or weight, then the reactor provides higher power handling capability, but more time and effort is required for securing the reactor

Engineering Contradiction:
Improvepower handling capabilityVSAvoidsecuring time
Core Design Contradiction:
PowerVSLoss of time

Solution Approach 1:

The base is pre-designed with multiple sides having notches in different directions before installation. This preliminary configuration of diverse notch orientations eliminates the need for repositioning or additional adjustments during the securing process, regardless of the reactor's size or weight. Installers can directly align and secure the reactor in the required orientation without extra time-consuming operations.

Principle #10Preliminary action

3Adaptability or versatility

If conventional reactors are panel-mounted in orientations with securing notches perpendicular to gravity direction, then wiring flexibility is improved, but the reactors cannot be temporarily secured and require supporting the reactor while tightening screws

Engineering Contradiction:
Improvewiring orientation flexibilityVSAvoidsecuring process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The base is segmented into multiple sides with notches oriented in different directions. This allows selection of the appropriate side for mounting based on wiring requirements. When a side with notches perpendicular to gravity direction is used, the corresponding wiring flexibility is achieved without compromising the temporary securing capability, as the notch design on that side accommodates both functions simultaneously.

Inventive Principle:
Principle #1Segmentation

AI summary

A reactor according to an embodiment of the present disclosure includes a reactor main body including cores and coils wound on the cores; and a base having a polygonal shape extending outside the reactor main body, configured to support the reactor main body. In at least two sides that are not opposite each other, of a plurality of sides of the base, a plurality of notches are formed inwardly from each of the sides, so that axes of fasteners to temporarily secure the base to an installation target object pass through the notches.
