Wire Harness Device Integrating On-Site Molding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wire harness manufacturing devices require large storage spaces and labor for managing extensive stocks of external parts, as they need to maintain a wide working area and store many external components due to the inability to manufacture wire harnesses without sufficient external parts.
Innovation Solution
A manufacturing device that integrates a molding machine to form external parts and a wiring board with a binding device to wire electric wires into prescribed forms, allowing for the on-site production of only the necessary external parts, thereby reducing the need for extensive storage and management of external parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If parts boxes storing extensive stocks of external parts are installed in the vicinity of the wire harness manufacturing device, then the manufacturing operation can be prevented from stopping due to shortage of external parts, but the installed area of the manufacturing device is increased and a wide working space is required in the factory
Solution Approach 1:
The patent extracts the external parts storage function from the manufacturing device vicinity and relocates it to a centralized storehouse. The parts boxes are removed from near the manufacturing device and stored in a dedicated storage area, eliminating the need for wide working space while maintaining continuous operation capability through centralized stock management.
Solution Approach 2:
The patent creates a universal storage system where a single centralized storehouse serves all manufacturing needs. Instead of having multiple distributed parts boxes throughout the factory, one centralized location with sufficient capacity serves the entire wire harness manufacturing operation, reducing total space requirements.
2Reliability
If parts boxes storing extensive stocks of external parts are installed in the vicinity of the wire harness manufacturing device, then the manufacturing operation can be prevented from stopping due to shortage of external parts, but a management of the stocks is necessary which requires labor and time
Solution Approach 1:
The patent extracts the stock management responsibility from the manufacturing process and consolidates it in a centralized location. By removing parts boxes from the manufacturing vicinity and storing them centrally, the system reduces the frequency and complexity of stock management operations required during manufacturing.
Solution Approach 2:
The patent prepares external parts in advance by storing them in sufficient quantities in a centralized storehouse before manufacturing begins. This preliminary stock preparation ensures that parts are readily available when needed, eliminating the need for frequent management interventions during the manufacturing process.
3Ease of operation
If a wide working space is ensured in the factory to accommodate the installed area of the wire harness manufacturing device, then the manufacturing device can operate without space constraints, but the factory requires a larger overall area
Solution Approach 1:
The patent extracts the storage function from the working space and relocates it to a dedicated storehouse. This separation allows the manufacturing device to operate in a compact area without needing wide working space for part storage, while the factory overall area is optimized by having a separate, efficiently utilized storage location.
