Agricultural Spreader Guard Visual Locking via Resilient Buffers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing container for agricultural distribution machines lacks a clear visual indication of whether the protective device is correctly locked, making it difficult for operators to verify the locking status from a distance.
Innovation Solution
Incorporating resilient intermediate elements, such as rubber buffers or spring elements, between the protective device and the container parts to maintain the protective device in a visibly distinct position when not correctly locked, allowing it to be pressed at least 10° from the closed locking position and beyond the locking area, providing a clear visual cue for the operator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the protective device is locked by pressing it under the locking element, then the protective device is securely locked, but it becomes difficult to see from a distance whether the safety guard is actually locked
Solution Approach 1:
The patent applies a visual indication mechanism where the protective device itself serves as the indicator. When locked, the protective device is pressed under the locking element and assumes a closed position that is visually distinct from the unlocked position. This allows operators to immediately see the locking status without additional sensors or electronics, resolving the contradiction between reliable locking and visual detectability
Solution Approach 2:
The protective device performs dual functions: it provides physical protection when locked and simultaneously serves as a visual indicator of its own locking status. The device self-indicates its state through its position relative to the locking element, eliminating the need for separate monitoring systems and maintaining both reliability and detectability
2Difficulty of detecting and measuring
If resilient intermediate elements are added to provide visual indication, then the locking status becomes clearly visible, but the device complexity increases
Solution Approach 1:
The patent introduces resilient intermediate elements as a mechanical mediator between the protective device and the container. These elements automatically translate the locking action into a visible positional change of the protective device. The intermediary components are simple in nature (rubber buffers or spring elements) and integrate seamlessly into the existing structure, providing clear visual indication without significantly increasing overall device complexity
Solution Approach 2:
The resilient intermediate elements change the positional parameter of the protective device based on the locking state. When the locking element engages, it compresses the resilient elements, causing the protective device to move to a specific position that is easily visible from a distance. This parameter change provides clear visual feedback while using simple, low-complexity components

Function Achieved in This Case
This solution creates a robust and reliable visual display of the locking status without additional sensors or electronics, ensuring operators can easily identify and correct the locking position, enhancing operational safety.
Implementation Method 1
resilient intermediate elements that move the protective device in the opening direction are arranged between the protective device and the container parts
Implementation Method 2
A simple configuration of the resilient intermediate elements can be achieved in that the intermediate elements are designed as rubber buffers or spring elements

AI summary
The container has a protective device (3) i.e. wire element, for protection of access to moving parts within the container. A locking element (7) is attached to the protection device to lock the protection device in a protective position. The protective device is swingably secured on a side (8) by joints (4) at the parts and rests against the parts on another side at a distance to the joints by a support unit (6). Intermediate elements moving the protective device in an opening direction are arranged between the protective device and the parts on the former side of the protective device. The intermediate elements are designed as rubber buffers and spring elements. The container parts are provided as a reservoir (2) and a container wall (5).
