Solution Overview

Problem

Construction machines with multiple cameras require complex operations using both display change and camera change switches to display desired images on the display unit, making it cumbersome for operators.

Innovation Solution

A construction machine with a single camera switch that allows operators to easily switch between images from different cameras on the display unit, simplifying the process of selecting desired images.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple cameras are installed to capture images from different positions, then the operator can view images from multiple positions, but the operation complexity increases due to requiring both display change switch and camera change switch

Engineering Contradiction:
Improveimage viewing capabilityVSAvoidoperation complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent combines the display change function and camera change function into a single integrated switch system. The switch unit has multiple switch elements that can select both the display type and camera simultaneously through a unified operation interface, eliminating the need for separate display change switch and camera change switch operations.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The switch unit is designed to perform multiple functions: it can select between different display types (vehicle information display or camera image display) and simultaneously select between multiple cameras. This multi-functional switch reduces the number of separate controls needed and simplifies the overall operation.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If display change switch and camera change switch are provided separately, then display type and camera can be selected independently, but the number of switches and operational steps increases

Engineering Contradiction:
Improveselection flexibilityVSAvoidnumber of switches
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges multiple separate switches (display change switch and camera change switch) into a single integrated switch unit. This switch unit contains multiple switch elements that handle both display selection and camera selection through one unified component, reducing the total number of switches in the system.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The switch unit is designed as a universal control device that can perform multiple selection functions. It includes switch elements that can independently control display type selection and camera selection, providing the flexibility of separate controls while being implemented as a single integrated device.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

[Object] To provide a construction machine capable of displaying a desired image on a display unit with a simple operation. [Means for Solution] A construction machine that includes a lower-part traveling body that performs a traveling operation, an upper-part turning body turnably mounted on the lower-part traveling body, an operator's cab mounted on the upper-part turning body, multiple image capturing devices mounted on the upper-part turning body, and a display unit mounted in the operator's cab to simultaneously display operating information regarding an operating condition and an image including at least one of captured images captured with the image capturing devices, wherein the display unit is configured to change at least one of a display position of the operating information and the displayed captured image, in response to an operation of a single changeover switch.
