Motor Unit Mounting Orientation for Multi-Tool Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor units are limited in the types of working units they can be attached to, as they are designed for specific orientations, restricting their applicability to various working units.
Innovation Solution
A motor unit system that includes a motor, an output member, and a fixing member, allowing it to be selectively fixed to different working units and oriented in various directions relative to a reference plane, enabling compatibility with a broader range of working units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the motor unit is designed for a specific orientation only, then the fixing and installation are simplified, but the types of working units to which it is applicable are limited
Solution Approach 1:
The motor unit is designed with a universal fixing member that can be attached to multiple types of working units in different orientations. The fixing member includes a mounting portion with multiple mounting holes arranged in different directions, allowing the motor unit to be fixed to various working units (grass trimmer, edger, cultivator, etc.) without requiring orientation-specific design variations.
Solution Approach 2:
The motor unit incorporates a movable connection mechanism between the motor housing and the output member, allowing the relative position and orientation to be adjusted. This dynamic adjustment capability enables the motor unit to adapt to different working unit configurations while maintaining a simplified fixed design for each individual attachment.
2Adaptability or versatility
If the motor unit is designed to accommodate multiple orientations, then the adaptability to working unit types increases, but the device complexity increases
Solution Approach 1:
The fixing member is designed as a universal component that integrates multiple mounting capabilities into a single structure. The mounting portion includes multiple mounting holes arranged in different directions, allowing one fixing member to serve multiple attachment purposes without requiring separate fixing members for each orientation or working unit type.
Solution Approach 2:
The motor unit combines the motor housing, output member, and fixing member into an integrated assembly. The fixing member is directly formed as part of the motor housing structure, merging multiple functions (motor mounting, output transmission, and working unit attachment) into a single unified component, thereby reducing overall system complexity.

AI summary
A system may include: a motor unit comprising an output member and a fixing member; a first working unit configured to be selectively fixed to the fixing member; and a second working unit configured to be selectively fixed to the fixing member. In a case where the fixing member is fixed to the first working unit, the fixing member of the motor unit may be oriented in a first direction relative to a reference plane when the first working unit and the motor unit are in a first working posture relative to the reference plane. In a case where the fixing member is fixed to the second working unit, the fixing member of the motor unit may be oriented in a second direction relative to the reference plane when the second working unit and the motor unit are in a second working posture relative to the reference plane.
