Cabin-Mounted Laminated Lamp Support for Visible Work Vehicle Status
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing state indication devices for work vehicles, such as combine harvesters, lack a secure and easily visible arrangement, as they are not specifically described in terms of position or support structure, making them prone to falling or not being easily visible from outside the machine body.
Innovation Solution
A state indication device is provided on a work vehicle with a support part integrated into the cabin, allowing it to be centrally positioned on the machine body and having a changeable posture from a use state to a retracted state, connected to an antenna unit via a support member, ensuring firm support and visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the state indication device is provided upright on an upper part of a cabin covering a driving part, then the indication is visible from outside the machine body, but the device may not be firmly supported and could fall off during work
Solution Approach 1:
The patent combines the state indication device with the antenna unit into an integrated assembly, where both components share a common support structure on the cabin. This merging ensures that the indication device benefits from the stable support of the antenna mounting system while maintaining its visibility function.
Solution Approach 2:
The patent provides specific guidance on the support structure configuration before the device is installed, specifying that it should be firmly supported on the cabin. This preliminary design consideration ensures proper support stability is built into the installation from the outset, preventing falling during work.
2Reliability
If the state indication device is arranged in a fixed position on the cabin, then it is firmly supported, but it may obstruct transportation or storage when not in use
Solution Approach 1:
The patent makes the support structure dynamic by enabling the state indication device to change its posture between a use state (extended outward for visibility) and a retracted state (folded back for compact storage). This dynamic capability allows the device to adapt to different operational requirements without compromising support stability when in use.
3Illumination intensity
If the state indication device is positioned centrally on the machine body, then it is easily visible from all directions, but it requires a more complex support structure
Solution Approach 1:
The patent merges the state indication device with the antenna unit, allowing both to share a common support structure. This integration simplifies the overall support system while achieving central positioning for optimal visibility, as the combined unit can be mounted centrally without requiring separate complex support structures for each component.
