Wiring Member with Orientation Recognition Mark for Robotic Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual assembly of wire harnesses and connector fitting operations in vehicle manufacturing are inefficient due to high degree of freedom in wire harness movement and lack of fixed connector positions, making automation challenging, especially when wire harnesses branch halfway.
Innovation Solution
A wiring member comprising a wire-like transmission member held two-dimensionally by a sheet-like holding member with a connector attached, featuring an orientation recognition mark for robotic assembly, allowing precise positioning and orientation recognition of connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional wire harness structure is used, then the wire harness has high degree of freedom of movement, but the connectors cannot be correctly recognized and held by robot
Solution Approach 1:
A positioning member is introduced as an intermediary between the wire harness and the robot. This positioning member has a positioning hole that receives the connector, fixing its position and orientation in space. The robot then grasps the positioning member instead of the connector directly, enabling precise robotic assembly while maintaining the flexibility of the wire harness structure.
2Device complexity
If connectors are not held in guide case or connector holders, then the wire harness structure is simpler, but automation of connector fitting operation becomes difficult
Solution Approach 1:
The positioning member serves as a mediator that enables automation without requiring complex guide cases or connector holders. By providing a simple positioning hole that receives the connector, it allows the robot to grasp and manipulate the connector accurately, thus achieving automation with minimal additional structure.
Solution Approach 2:
The system is segmented into distinct functional elements: the wire harness, the connector, the positioning member, and the robot. The positioning member is a separate, simple component that bridges the gap between the flexible wire harness and the precise robotic manipulation, allowing each element to maintain its inherent characteristics while working together.
3Adaptability or versatility
If wire harness branches halfway, then the wiring member can accommodate complex routing, but conventional technologies cannot handle such configurations
Solution Approach 1:
The positioning member acts as a universal intermediary that works regardless of the wire harness configuration. Whether the wire harness is straight or branches halfway, the positioning member provides a standardized interface for the robot to grasp the connector, making automated assembly feasible for complex routing configurations.
