Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle cabins for agricultural machines lack effective solutions for enhancing safety and ergonomics, particularly in terms of visualization and information access for operators.
Innovation Solution
A vehicle cabin design for agricultural work machines featuring a visualization device with front and rear visualization units mounted on the A-pillar and B-pillar, respectively, allowing for easy and ergonomic access to information without obstructing the operator's essential visual field.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If visualization units are arranged randomly within the vehicle cabin, then information can be displayed to the operator, but the essential field of vision is obstructed and ergonomics deteriorate
Solution Approach 1:
The patent applies dimensionality change by mounting visualization units on vertical surfaces (A-pillars and B-pillars) rather than horizontal surfaces (dashboard, windshield). This vertical arrangement utilizes the unused vertical space in the cabin, allowing information display without obstructing the operator's horizontal field of vision. The visualization units are positioned at different heights and locations on the pillars, creating a three-dimensional information display architecture that separates information access from the primary viewing plane.
Solution Approach 2:
The patent segments the visualization system into multiple distributed units rather than a single centralized display. By placing visualization units on both A-pillars and B-pillars, the system divides information presentation across multiple locations, allowing the operator to access different types of information at different positions without requiring all information to be visible from a single viewpoint, thus maintaining ergonomics while improving information accessibility.
2Loss of information
If monitors are placed within the cabin to display information, then the operator can access data, but safety is compromised due to obstructed peripheral vision
Solution Approach 1:
The patent relocates visualization units from the horizontal dashboard plane to the vertical pillar surfaces, utilizing the z-dimension (vertical height) that does not interfere with the operator's horizontal peripheral vision. This spatial reconfiguration allows information to be displayed in a dimension that is peripheral to the main viewing area, thus maintaining safety while improving information accessibility.
Solution Approach 2:
The A-pillars and B-pillars serve as intermediary structures that carry the visualization units. These pillars act as mediators between the information display requirement and the safety requirement, providing mounting surfaces that are outside the critical viewing zone but still within the operator's peripheral awareness, thus resolving the conflict between information display and safety.
3Measurement precision
If visualization devices are positioned for direct viewing, then information is clearly visible, but the operator's peripheral field of vision is blocked
Solution Approach 1:
The patent transitions the visualization system from a two-dimensional dashboard surface to a three-dimensional arrangement on vertical pillars. This allows information to be displayed at multiple heights and angles, making it visible through peripheral vision without requiring the operator to shift attention from the road. The vertical placement on pillars creates viewing opportunities that do not compete with the central forward view.
