Rotating Jaw Attachment for Earth Moving Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional earth moving machine attachments, such as mechanical and hydraulic jaws, require complete dismantling for different operations, leading to time loss, increased labor, and accident risks due to the lack of an adjustment mechanism, which existing solutions have not adequately addressed.
Innovation Solution
A jaw attachment with a rotating and moving lower body that can perform both jaw and ripper functions without detachment from the fixed upper body, utilizing a 180-degree rotation mechanism and connection members like DIN912 bolts to switch between functions efficiently, allowing for the replacement of only the lower body when worn.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional mechanical or hydraulic jaws are used for excavation operations, then grabbing and displacement of materials can be performed, but the attachments cannot perform other work types and require complete dismantling for different operations
Solution Approach 1:
The jaw attachment is designed with a rotatable lower body that can be positioned in multiple orientations to perform different functions. The lower body can rotate to enable both jaw function (for grabbing materials) and ripper function (for excavating materials), allowing a single attachment to perform multiple work types without complete dismantling.
Solution Approach 2:
The attachment is divided into separable components: a fixed upper body and a moving lower body connected by connection members. This segmentation allows the lower body to be independently rotated and repositioned to change functions, or replaced separately if worn, without removing the entire attachment from the machine.
2Ease of operation
If traditional attachments without adjustment mechanisms are used, then结构简单 (structure is simple), but complete dismantling is required for each operation change causing labor and time loss
Solution Approach 1:
The lower body is designed as a dynamic component that can rotate and be repositioned relative to the fixed upper body. Connection members allow the lower body to be easily detached and reattached in different positions, enabling quick function switching without complex adjustment mechanisms or complete dismantling.
3Ease of repair
If complete detachment of jaw attachments is performed for replacement, then worn parts can be replaced, but labor and time loss occur and accident risk increases
Solution Approach 1:
The attachment is segmented into a fixed upper body and a moving lower body that can be independently handled. When the lower body becomes worn, only that component needs to be replaced by disconnecting connection members, rather than removing the entire attachment from the machine, reducing both time and accident risk.
4Ease of manufacture
If traditional single-function attachments are used, then manufacturing is simpler, but separate attachments are needed for different operations increasing overall complexity
Solution Approach 1:
The attachment integrates multiple functions into a single device. The lower body can be positioned in different orientations to provide both jaw function and ripper function, eliminating the need for multiple separate attachments while maintaining manufacturing simplicity through modular design with standardized connection members.
