Laminate Trimmer Component Layout for Compact Electronics Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laminate trimmers face challenges in accommodating additional electric components without compromising their compact design, as the space between the electric motor and housing is often underutilized.
Innovation Solution
The laminate trimmer incorporates a controller aligned with the electric motor in the axial direction, with other electric components positioned in a compartment between the controller and the motor, and a battery opposite the contact portion, allowing for a compact arrangement of components like a wireless communication adaptor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electric components are accommodated in the upper portion of the housing around the electric motor, then the housing space is utilized in a space-saving manner, but the compactness of the apparatus cannot be maintained when new electric components are added
Solution Approach 1:
The patent transitions from accommodating electric components only in the upper portion of the housing to utilizing the axial direction between the electric motor and the base. This dimensional change allows components to be arranged in a previously underutilized space, enabling addition of new components without increasing the overall housing volume.
Solution Approach 2:
The housing space is segmented into distinct regions: the upper portion around the motor and the axial space between the motor and base. This segmentation allows independent utilization of each region for different components, maximizing space efficiency and enabling flexible component arrangement.
2Device complexity
If the electric motor is positioned with its axis coaxial with the housing axis, then the structure is simplified and space-saving, but the arrangement of electric components becomes constrained
Solution Approach 1:
The patent utilizes the axial direction (another dimension) between the motor and base to arrange electric components. This complements the coaxial configuration by providing an additional spatial dimension for component placement, thereby increasing arrangement flexibility without compromising structural simplicity.
Solution Approach 2:
Electric components are nested within the axial space between the motor and base, effectively utilizing the available volume. This nesting approach allows multiple components to be accommodated in a compact manner while maintaining the simple coaxial motor configuration.

AI summary
A portable machining apparatus facilitates addition of new electric components with an intended arrangement of various electric components. The portable machining apparatus includes a housing, an electric motor installed in the housing and including a motor shaft extending in an axial direction, a tip tool partially or fully exposed outside the housing and rotatable by the electric motor, a controller installed in the housing and aligned with the electric motor in the axial direction to control an operation of the electric motor, and a first electric component and a second electric component installed in an electric component compartment between the controller and the electric motor. The first electric component and the second electric component are aligned in a same plane perpendicular to an axis of the motor shaft.
