Work Machine Rope Holder Layout for Secure Trailer Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work machines face difficulties in being securely fixed to carrier boxes or trailers due to the lack of defined attachment points, leading to instability during transportation.
Innovation Solution
The work machine is designed with forward and backward holders configured to hold or pass ropes, specifically at the front-wheel unit and bumper areas, allowing for stable fixation by distributing the load and preventing displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ropes are wound around arbitrary portions of the work machine (such as the front-wheel unit or step forward), then the work machine can be transported on a carrier box, but it is difficult to determine appropriate portions to wind ropes around, leading to unreliable fixation
Solution Approach 1:
The body is divided into functional sections with dedicated attachment points (first holder at front portion, second holder at back portion). Each holder is a distinct structural element designed specifically for rope attachment, separating the fixation function from other body components.
Solution Approach 2:
Holders serve as intermediary components between the rope and the work machine body. The first holder (at the front portion) and second holder (at the back portion) act as dedicated interface elements that facilitate reliable rope attachment without requiring direct attachment to arbitrary body parts.
2Reliability
If no dedicated holders are provided on the work machine, then the structure remains simple, but the work machine cannot be securely fixed to a carrier box
Solution Approach 1:
The fixation system is segmented into separate holder components rather than integrating attachment features into the main body structure. The first holder and second holder are distinct elements that can be independently positioned and designed for their specific attachment functions.
Solution Approach 2:
Holders serve as intermediary components that provide dedicated rope attachment points without requiring complex integration into the main body. These holders act as simple interface elements that bridge the rope and body, maintaining structural simplicity while enabling secure fixation.
3Ease of operation
If multiple holders are disposed at wide spacing to prevent obstruction of driver's view, then the driver's view is clear, but the load on front wheels increases when ropes are fastened
Solution Approach 1:
The attachment system utilizes the lateral dimension by positioning holders at opposite lateral sides of the driver's seat. This lateral distribution allows ropes to be attached at wide spacing for clear driver view while the symmetric positioning balances the load distribution to prevent excessive force on front wheels.
Solution Approach 2:
The holders are positioned asymmetrically relative to the front wheels but symmetrically relative to the driver's seat, creating a balanced load distribution that accommodates both driver view requirements and wheel load constraints.

AI summary
A work machine includes: a body including: a body frame; a driver's seat at a central portion of the body; a power source at a back portion of the body; and a front-wheel unit disposed at a front portion of the body and extending in a left-right direction of the body, wherein the body has a forward portion provided with at least one first holder configured to hold a rope and/or allowing the rope to pass therethrough. The forward portion is provided with two or more first holders which are each usable as an independent holder or which are usable in conjunction with each other to allow a rope to pass through both holders.
