Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual process of setting and retracting parking stands for loader assemblies is tedious, time-consuming, and hazardous, requiring precise alignment for reattachment, which poses challenges in efficiency and safety.
Innovation Solution
A loader parking stand assembly with a latch and lock mechanism that automatically secures and supports the boom and bucket, featuring pivotally attached struts and a locking plate with divots for unidirectional locking, allowing for easy transition between stowed and parking positions, and includes a ratchet-type mechanism for locking the support leg in an extended position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation of parking stands is used, then the operator can control the positioning, but the process is tedious, time-consuming, and hazardous
Solution Approach 1:
The parking stand system performs self-positioning and self-locking through automatic sensing and actuation. The system detects boom position, automatically extends the parking stand to the correct angle, and engages the locking mechanism without operator intervention, making the system serve itself rather than requiring manual operation
Solution Approach 2:
The patent replaces manual mechanical operation with an automated control system that uses sensors to detect boom position and electronically controls hydraulic actuators to position and lock the parking stand, substituting the manual mechanical system with an electro-hydraulic automated system
2Manufacturing precision
If precise alignment is required for reattachment, then the connectors will align properly, but the manual positioning process becomes more complex and time-consuming
Solution Approach 1:
The system uses sensors to detect the actual position of the boom and provides feedback to the control system, which then adjusts the parking stand angle accordingly to ensure precise alignment of connectors for reattachment, achieving accurate positioning through closed-loop control rather than complex mechanical positioning mechanisms
Solution Approach 2:
The parking stand serves multiple functions: it provides structural support for the boom, enables precise alignment of connectors for reattachment, and incorporates an automatic locking mechanism. This multi-functionality reduces the need for separate alignment devices and simplifies the overall system
3Ease of operation
If the parking stand is manually extended and retracted, then the operator can control the positioning, but the operator is exposed to hazards from heavy equipment
Solution Approach 1:
The parking stand system performs self-extension and self-retraction through automated hydraulic actuators controlled by the system's control unit, eliminating the need for operator proximity to heavy moving parts and thereby removing the safety hazards associated with manual operation
Solution Approach 2:
The patent introduces an intermediary automated control system that mediates between the operator's intent and the heavy mechanical components. The control system acts as an intermediary layer that translates operator commands into automated actuator movements, keeping the operator at a safe distance from hazardous equipment
