Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of air cleaners and pipes in construction machines is inefficient due to interference with multiple obstacles in a limited space, leading to potential damage and reduced space utilization.
Innovation Solution
A construction machine design where the air cleaner and pipe are mounted on a seat plate, allowing for displacement between two positions to avoid interference with obstacles like radiators and oil filling portions, while maintaining compactness and efficient assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the air cleaner and pipe are installed in a limited space between obstacles, then the space utilization is improved, but the installation efficiency deteriorates due to interference with obstacles
Solution Approach 1:
The air cleaner is designed with a movable structure that allows it to shift position dynamically. The air cleaner can be displaced between a first position (when the obstacle is in a first state) and a second position (when the obstacle is in a second state), enabling the system to adapt to different spatial configurations and avoid installation interference
Solution Approach 2:
The mounting structure is divided into separate components including a first mounting structure, a second mounting structure, and a movable structure. This segmentation allows independent adjustment of each component to achieve optimal positioning and avoid obstacles during installation
2Adaptability or versatility
If the air cleaner is made movable to avoid obstacles, then the installation flexibility is improved, but the device complexity increases
Solution Approach 1:
The movable structure integrates the air cleaner with its mounting mechanisms into a unified assembly. The first mounting structure, second mounting structure, and movable structure work together as a coordinated system, reducing the need for separate complex control mechanisms while maintaining installation flexibility

AI summary
Provided is a construction machine including an air cleaner and allowing the air cleaner to be easily installed with no enlargement of an installed space while surely avoiding the interference with other structure. The construction machine includes: an air cleaner (22); a pipe (32) connected to an exhaust port of the air cleaner (22); a seat plate (34) on which the air cleaner (22) and the pipe (32) are mounted to form a subassembly (A1); and a device (19) including an upper surface on which the subassembly (A1) is mounted to form a device-assembly. The subassembly (A1) is allowed to be displaced between a first position apart from a first structure (14) and a second position close to the first structure (14) and apart from a second structure (19a) and to be fixed at each of the positions.
