Solution Overview
Problem
Existing single-axle implement carriers, such as sickle bar mowers, require manual operation and struggle with stability on steep slopes and uneven terrain, necessitating constant human intervention.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the single-axle implement carrier uses a fixed center of gravity position, then the structure is simple, but it cannot maintain stability on steep slopes and uneven terrain
Solution Approach 1:
The patent applies the dynamics principle by making the center of gravity position adjustable rather than fixed. The drive axle is made movable relative to the chassis, allowing the center of gravity to be dynamically repositioned forward or backward depending on terrain conditions. This enables the implement carrier to maintain stability on steep slopes while avoiding excessive structural complexity through a relatively simple movable axle mechanism.
2Ease of operation
If the single-axle implement carrier requires manual operation, then the control is straightforward, but the manual labor is strenuous and constant human intervention is needed
Solution Approach 1:
The patent applies the self-service principle through autonomous control systems that enable the implement carrier to operate without constant human intervention. Sensors detect terrain conditions and obstacles, and the control system automatically adjusts the drive axle position and operates the implement, allowing the machine to serve itself in navigating terrain and performing tasks.
Solution Approach 2:
The patent replaces manual mechanical control with automated control systems. Instead of requiring an operator to manually steer and control the implement carrier, electronic sensors and control algorithms substitute for human operation, automatically managing the vehicle's movement and implement operation based on detected conditions.
3Force
If the drive axle position is fixed relative to the chassis, then the manufacturing is simple, but the support force of the attachment cannot be regulated
Solution Approach 1:
The patent makes the drive axle movable relative to the chassis, allowing dynamic adjustment of the center of gravity position. This enables regulation of the attachment's support force by repositioning the axle forward or backward, while maintaining manufacturing simplicity through a relatively straightforward movable connection mechanism rather than complex adjustable systems.

AI summary
The invention relates to a single-axle implement carrier, to which one or more implements, such as a cutter bar (4), can be attached. The single-axle implement carrier has a chassis (1), an electric drive (11), and a drive axle (10). The drive axle (10) can be driven by the electric drive (11) in order to move the single-axle implement carrier over a working area (AF). The position of the centre of gravity (SP) of the single-axle implement carrier relative to the drive axle (10) can be changed in order to regulate the contact force of the implement on the working area (AF). The invention additionally relates to a single-axle implement unit comprising a single-axle implement carrier of this kind and to a working machine system having a plurality of single-axle implement carriers of this kind.
