Solution Overview

Problem

Construction robots on construction sites face inefficiencies due to high setup times and limited availability, necessitating an effective solution for their deployment and maintenance.

Innovation Solution

A mobile tool container designed for construction robots, featuring a charging side and a maintenance side with opening elements, allowing for efficient loading, unloading, maintenance, and charging of the robots, minimizing setup times.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the construction robot is housed in a mobile tool container for efficient deployment, then the availability and productivity of the robot is improved, but the setup time for loading and maintenance becomes a limiting factor

Engineering Contradiction:
Improveavailability of construction robotVSAvoidsetup time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The tool container is divided into distinct functional areas: a loading side for robot entry/exit and a maintenance side for service operations. Each side has its own opening elements, allowing simultaneous or separate access for different operations. This segmentation enables independent access to the robot for loading/unloading and maintenance tasks without requiring the other operation to wait, thereby reducing overall setup time while maintaining high productivity.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the tool container has a compact design to operate in narrow spaces, then the adaptability to construction sites is improved, but the accessibility for maintenance work becomes limited

Engineering Contradiction:
Improveoperation in narrow spacesVSAvoidaccessibility for maintenance
Core Design Contradiction:
Adaptability or versatilityVSEase of repair

Solution Approach 1:

The tool container utilizes the vertical dimension by incorporating a top-opening element that can be folded upwards. This vertical opening provides extensive access to the robot's upper areas, including robot arms and overhead components, without requiring the container to be wider. The vertical flap opening mechanism maintains a compact horizontal footprint while delivering full maintenance accessibility from multiple angles, resolving the conflict between compactness and serviceability.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of operation

If the opening element on the maintenance side extends over at least half of the maintenance side, then the ease of maintenance operation is improved, but the structural complexity of the container increases

Engineering Contradiction:
Improvemaintenance operationVSAvoidcontainer structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The maintenance side opening element is implemented as a segmented structure with multiple flaps or panels that can be opened independently or together. This segmentation allows the opening mechanism to cover at least half of the maintenance side area while using simpler, modular components rather than a single complex large-scale mechanism. Each segment can be independently supported and operated, reducing the overall structural complexity while maintaining ease of maintenance access.

Inventive Principle:
Principle #1Segmentation
