Solution Overview

Problem

Conventional current measuring devices face challenges in reducing size and increasing mountability of electronic components, leading to increased overall size and potential heat influence on components.

Innovation Solution

The current measuring device is designed with a circuit board disposed upright relative to a conductor, allowing it to be housed within the width of the conductor, reducing the mount area and mitigating heat influence on electronic components by positioning them away from the conductor.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If electronic components are mounted on the circuit board in the conventional structure, then the device can process sensed signals, but the overall size of the device increases

Engineering Contradiction:

Improvesignal processing capabilityVSAvoiddevice size

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The circuit board is integrated with the conductor in a merged structure where the circuit board is disposed upright relative to the conductor. The conductor serves dual purposes as both the current-carrying element and the mounting base for the circuit board, eliminating the need for separate mounting structures and reducing overall device size while maintaining signal processing capability

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The circuit board is positioned in a different spatial dimension (upright orientation) relative to the conductor rather than being placed parallel to it. This vertical arrangement allows the circuit board to be disposed within the width of the conductor, utilizing the third dimension to reduce the device's footprint area while maintaining full functionality

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Area of stationary object

If the circuit board is disposed within the width of the conductor, then the mount area is reduced, but the electronic components may be exposed to heat from the conductor

Engineering Contradiction:

Improvemount areaVSAvoidheat influence on components

Core Design Contradiction:

Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The circuit board is designed with non-uniform component distribution where heat-sensitive electronic components are positioned in regions farther from the conductor, while less heat-sensitive components can be positioned closer. This local differentiation of component placement allows the circuit board to be disposed within the conductor's width, reducing mount area, while protecting sensitive components from thermal exposure through strategic positioning

Inventive Principle:

Principle #3Local quality
