Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional clamp or parallelogram-type attachment devices are used, then the motor can be attached to the craft, but the installation process is time-consuming and requires operators to bend over while supporting the motor weight, risking back injuries
Solution Approach 1:
The attachment device is divided into separate modular components: a support element fixed to the craft, a connection interface with pivot and rotational connections, and an arm coupled to the motor. This segmentation allows each component to be independently positioned and connected, enabling rapid assembly without requiring the operator to manually handle the entire motor assembly.
Solution Approach 2:
The connection interface acts as an intermediary mechanism between the support element and the arm. It incorporates pivot connections for vertical movement and rotational connections for horizontal movement, automatically positioning the motor without requiring manual support or bending by the operator during installation.
2Adaptability or versatility
If the connection interface allows movement of the arm between pivot positions for raising and lowering the motor, then adaptation to water depth is enabled, but the structural complexity increases
Solution Approach 1:
The connection interface incorporates a pivot connection that allows the arm to move dynamically between pivot positions, enabling the motor to be raised or lowered according to water depth. This dynamic adjustment capability provides adaptability while maintaining a relatively simple structural implementation through standard pivot joint mechanics.
3Adaptability or versatility
If the axis of rotation and pivot axis are positioned orthogonally, then the motor can rotate in the moving state for steering and pivot for positioning, but the manufacturing precision requirements increase
Solution Approach 1:
The connection interface employs asymmetric arrangement of the pivot axis and rotational axis at orthogonal orientations. This asymmetric configuration enables independent movement in vertical and horizontal planes, providing both positioning and steering capabilities. The orthogonal arrangement is achieved through standard manufacturing practices for pivot and rotational joints, avoiding excessive precision requirements.

AI summary
The invention relates to an attachment device (1) for attaching an outboard motor (22) to a craft. The attachment device (1) comprises an arm (2) which can be coupled to the motor (22), a support (3) which can be coupled to the craft, and a connecting interface (4) which can be inserted between the arm (2) and the support (3). The connection interface (4) can be pivotably coupled to the arm (2) by means of a so-called pivot connection (5) comprising at least one pivot axis (XX1) for a movement of the arm (2) between two end pivot positions. The connection interface (4) can be rotatably coupled to the support (3) by a so-called rotational connection (7) comprising at least one axis of rotation (YY1) to allow, in the coupled state of the connection interface (4) to the arm (2) and to the support (3), a movement of the arm (2) and of the connection interface (4) about the axis of rotation (YY1) over an angular range at least equal to 160°, preferably at least equal to 180°, and the axis of rotation (YY1) and the pivot axis (XX1) are orthogonal to each other.
