Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural loading wagons require laborious and time-consuming manual adjustments of the loading flap to accommodate different crop types, posing safety risks and inefficiencies in operation.
Innovation Solution
A manual adjustment mechanism for the loading flap, accessible from the ground, using a transmission gear and a manual adjusting lever to easily set various operating positions without tools, combined with a holding device and sensor system for automatic scraper floor activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the loading flap is made height-adjustable to accommodate different crop types and loading requirements, then the adaptability is improved, but the device complexity increases due to the adjustment mechanism
Solution Approach 1:
The loading flap is designed with a height-adjustable mechanism that allows it to change position dynamically. The adjustment mechanism includes a manual adjusting lever connected via transmission gear to the loading flap, enabling it to be moved between different height positions to accommodate various crop types and loading requirements.
Solution Approach 2:
The loading flap's height parameter can be changed to suit different operational conditions. By adjusting the height of the loading flap, the system adapts to different crop types (e.g., hay versus grass) and loading space utilization requirements, transforming a fixed-parameter component into a variable-parameter one.
2Ease of operation
If the adjustment mechanism is made accessible from ground level, then the ease of operation is improved, but the transmission gear complexity increases
Solution Approach 1:
A transmission gear acts as an intermediary mechanism between the manual adjusting lever at ground level and the loading flap positioned higher up. This transmission gear transmits the adjusting movement from the ground-level lever to the loading flap, enabling easy operation from ground level while maintaining mechanical connection.
Solution Approach 2:
The manual adjusting lever with transmission gear replaces the need for operators to physically access and manually adjust the loading flap at height. The mechanical system substitutes human physical intervention at dangerous heights with a ground-level control mechanism.
3Object-affected harmful factors
If a manual adjusting lever is provided on the outer side at ground level, then the safety is improved by eliminating the need to climb, but the device complexity increases
Solution Approach 1:
The adjustment control function is extracted from the loading flap itself and placed at ground level via the manual adjusting lever. This extraction allows the operator to control the loading flap height from a safe position on the ground, removing the need to climb onto the loading space wall or into the loading area.
Solution Approach 2:
The transmission gear serves as a mechanical intermediary that connects the ground-level adjusting lever to the elevated loading flap. This intermediary mechanism transmits the adjustment force and movement from the safe ground level to the loading flap, eliminating direct human exposure to hazardous positions.
4Adaptability or versatility
If the loading flap is made pivotally mounted to allow various operating positions, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The loading flap is pivotally mounted on the upper front wall section, allowing it to rotate and assume various operating positions dynamically. This pivotal mounting enables the loading flap to be adjusted to different angles and heights depending on the crop type and loading requirements, transforming a static component into a dynamic one.
