Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machining devices for wood components require complex and maintenance-intensive storage systems with multiple belt conveyors, leading to increased costs and inefficiencies in workpiece loading and removal.
Innovation Solution
A processing device with a converter unit that can move both vertically and horizontally, eliminating the need for complex belt conveyors by using a belt conveyor unit or linear conveyor to efficiently load and remove workpieces between a workpiece storage device and the processing device, allowing for simpler and cost-effective operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If complex storage systems with multiple belt conveyors are used, then workpiece storage and transfer capability is improved, but device complexity and maintenance requirements increase
Solution Approach 1:
The patent combines the storage device and transfer unit into an integrated system where the transfer unit serves dual purposes: transferring workpieces to the machining device and returning processed workpieces to storage. This merging eliminates the need for separate conveyor systems for each direction, reducing overall device complexity while maintaining full transfer capability.
Solution Approach 2:
The transfer unit is designed as a multi-functional component that performs multiple operations: horizontal transport of workpieces, vertical positioning at different storage levels, and bidirectional transfer (to and from machining device). This universal design replaces multiple specialized conveyor systems with a single versatile unit.
2Productivity
If multiple storage systems are arranged on the machine, then workpiece throughput is improved, but maintenance intensity and costs increase
Solution Approach 1:
Multiple storage levels are integrated into a single unified storage system with a shared transfer unit, rather than using separate independent storage systems. This consolidation maintains the ability to store and process multiple workpieces simultaneously while reducing the total number of conveyor mechanisms that require maintenance.
Solution Approach 2:
The transfer unit is designed with movable and adjustable components that can dynamically position workpieces at different vertical levels and horizontal positions. This dynamic capability allows a single transfer unit to serve multiple storage levels, replacing what would otherwise require multiple fixed conveyor systems.
3Manufacturing precision
If complex belt conveyors are used for workpiece transfer, then transfer precision is improved, but cost and maintenance requirements increase
Solution Approach 1:
The transfer unit acts as an intermediary mechanism between the storage device and machining device, providing controlled and precise workpiece transfer. By using a dedicated transfer unit with controlled movement capabilities rather than complex conveyor systems, the patent achieves precise positioning while simplifying the overall device architecture.
