Connector Receiving Portion for Electric Power Tool
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric power tools, such as binding machines, face challenges in assemblability and maintainability due to connectors being simply pushed into empty spaces within the body portion, leading to poor integration and increased risk of damage from vibrations.
Innovation Solution
The implementation of a receiving portion within the body portion to securely hold and fix connectors, utilizing a collective connector design that can connect multiple wirings at once, and providing a structured arrangement of chambers and wiring protection portions to enhance the integration and protection of electrical components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If connectors are simply pushed into empty spaces inside the body portion due to routing of wirings, then wiring routing is simplified, but assemblability and maintainability of connectors deteriorate
Solution Approach 1:
The invention divides the body portion into functional zones: a connector receiving portion with dedicated mounting structures and a wiring routing portion. This segmentation allows connectors to be systematically mounted in designated areas with proper fixation, while wirings are routed through separate pathways, simplifying both connector assembly and wiring installation without interfering with each other.
Solution Approach 2:
The invention introduces an intermediary connector receiving portion that acts as a mediator between the connectors and the body portion. This receiving portion provides standardized mounting interfaces and fixation mechanisms, making connector installation easier and more maintainable, while also serving as an organized hub for wiring connections.
2Ease of operation
If connectors are simply pushed into empty spaces inside the body portion, then installation process is simplified, but reliability of connectors against vibration damage deteriorates
Solution Approach 1:
The connector receiving portion is pre-designed with mounting structures and fixation mechanisms built into the body portion structure. Connectors are installed into these pre-prepared receptacles with proper securing features, ensuring they are firmly fixed before the tool begins operation. This preliminary proper installation prevents vibration-induced loosening or damage during use.
3Ease of manufacture
If connectors are received in a structured receiving portion fixed to the body portion, then assemblability and maintainability of connectors are enhanced, but device complexity increases
Solution Approach 1:
The connector receiving portion is integrated into the body portion structure, merging the connector mounting function with the existing housing. This integration eliminates the need for separate connector mounts or additional fastening components, achieving improved connector assemblability while avoiding excessive increase in overall device complexity.
