Working Machine Communication Unit Layout for Unobstructed View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing working machines face challenges in providing a useful layout for the communication unit, which includes a communication device and an information processing device, that does not obstruct the user's views while being mounted on the machine body.
Innovation Solution
The communication unit is positioned rearward of the seat and lower than the upper end of the seat, overlapping it in a rear view, with a unit support and cover member configuration that includes a load receiver and elastic intervening member to manage the backrest's reclineable position, ensuring unobstructed views and secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the communication unit is mounted on the machine body, then data transmission function is provided, but the user's view may be obstructed
Solution Approach 1:
The communication unit is repositioned from a conventional location to a specific spatial coordinate system: rearward of the seat in the longitudinal direction and lower than the upper end of the seat in the vertical direction, overlapping the seat in rear view. This multi-dimensional positioning ensures the communication unit does not obstruct the user's front, rear, or side views while maintaining its data transmission function.
2Ease of operation
If the backrest portion is made reclineable, then user comfort is improved, but the communication unit may be deformed or damaged
Solution Approach 1:
A cover member is introduced as an intermediary protective structure between the reclineable backrest portion and the communication unit. The cover member includes a load receiver that contacts the backrest portion when reclined, preventing direct mechanical stress on the communication unit while allowing the backrest to remain reclineable for user comfort.
3Object-affected harmful factors
If the communication unit is positioned to not obstruct view, then user view is improved, but attachment security may be compromised
Solution Approach 1:
The attachment system is segmented into multiple functional components: a unit support for mounting the communication unit, a cover member with load receiver for protection, and an intervening member with elastic properties for cushioning. This segmentation allows the communication unit to be positioned optimally for viewing while maintaining secure attachment through distributed mechanical support.
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
This layout allows for an unobstructed user view and secure attachment of the communication unit, preventing deformation and ensuring effective data transmission without hindering the user's front, rear, or side views.
Implementation Method 1
an intervening member including an elastic member and provided between and in close contact with the cover member and the load receiver

AI summary
A working machine includes a machine body; a seat on the machine body; and a communication unit including an information processing device and a communication device to receive data from and transmit data to the information processing device, the communication device containing a communication antenna and configured to transmit data. The communication unit is located at a position rearward of the seat and lower than an upper end of the seat such that the communication unit overlaps the seat in rear view.
