Modular Load Tester Segmentation for Narrow Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large load testing apparatuses with multiple resistance units are cumbersome for transportation through narrow spaces due to their size, making it difficult to move them through elevators and other confined areas.
Innovation Solution
A load testing apparatus with multiple resistance units, where each unit is mounted on a separate base part with a cooling fan, and the units are configured to maintain a gap for insulation, allowing them to be transported and assembled in a more compact form, enabling easier setup and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple resistance units are integrated on a single base part, then the load testing apparatus can handle high voltage loads, but the apparatus becomes too large for transportation through narrow spaces
Solution Approach 1:
The load testing apparatus is divided into multiple independent modules, each consisting of a base part with a resistance unit and cooling fan assembly. These modular units can be transported separately through narrow spaces and then assembled at the destination, resolving the contradiction between handling high voltage loads and maintaining compact transportation dimensions.
2Length of moving object
If resistance units are positioned close together to reduce apparatus size, then transportation becomes easier, but insulation between adjacent resistance units is compromised
Solution Approach 1:
The resistance unit is nested within a frame made of insulating material that covers the side faces of the resistor groups. This nested insulating structure allows adjacent resistance units to be positioned close together for compact transportation while maintaining adequate insulation distance (second distance) between them for high voltage reliability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for efficient transportation and setup of the load testing apparatus by reducing its overall dimensions, maintaining insulation even at high voltages, and simplifying the assembly process by allowing separate handling and positioning of the base parts and resistance units.

AI summary
Problem To provide a load testing apparatus that is configured with a plurality of resistance units and can be transported and set up easily. Solution A load testing apparatus according to the present invention includes at least two resistance units each configured with a plurality of resistor-groups arranged in stages along z direction, which is a vertical direction, and including a frame configured with an insulating material covering a side face of the resistor-groups, each of the resistor-groups including resistors arrayed along a horizontal direction; and at least two base parts each including a cooling fan and provided separately. At least one of the resistance units are provided on a top of each of the base parts via an insulator. A face of the frame that at least faces another adjacent resistance unit is positioned in an inner side of a side face of the base part, on which the resistance unit is provided, by a first distance when viewed from above. The at least two resistance units are disposed to have a gap between the frames of adjacent resistance units, the gap being equal to or larger than a second distance to provide insulation between the adjacent resistance units. The second distance is twice the first distance. The first distance is equal to or larger than 45 mm.
