Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cutting machines face issues with the accidental fall of cutting pieces from output shelves due to limited Bakelite shelf length, requiring manual intervention and posing safety risks, especially with large panels and trimming operations.
Innovation Solution
A cutting machine equipped with an optical detector, such as a camera or infrared sensor, to monitor shelf occupancy, a central control unit to manage panel movement and support, and a trimming shelf for flexible support and cutting adjustments, reducing manual intervention and preventing panel falls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the Bakelite shelf length is kept short to save space, then the available space in the outlet section is improved, but the ability to support large panels is worsened, causing panels to fall off
Solution Approach 1:
The patent implements a movable shelf system that can dynamically adjust its position and configuration based on panel size. The shelf is not fixed but can be repositioned along the outlet section to provide adequate support for different panel dimensions, resolving the contradiction between space utilization and support stability.
Solution Approach 2:
The outlet section is divided into multiple segments or adjustable sections that can be independently positioned. This segmentation allows the system to adapt to different panel sizes by configuring the shelf segments appropriately, maintaining both compact space usage and adequate support capability.
2Reliability
If manual intervention is required to remove cut pieces, then the panel support stability is improved, but the operator distraction risk increases, leading to safety issues
Solution Approach 1:
The system incorporates automatic detection and alert mechanisms that monitor shelf occupancy and panel position. When a panel is at risk of falling or the shelf needs attention, the system automatically generates alerts or notifications, eliminating the need for continuous manual monitoring and reducing operator distraction risks.
Solution Approach 2:
The patent implements a feedback system with sensors that continuously monitor the state of panels and shelves. This feedback loop provides real-time information to the control system, which can then take automatic actions or alert operators only when necessary, reducing the need for constant manual intervention while maintaining safety.
3Reliability
If the shelf is made longer to accommodate large panels, then the panel support capability is improved, but the outlet section space is worsened, reducing production efficiency
Solution Approach 1:
The shelf system is designed to be dynamic and reconfigurable rather than statically long. It can extend or reposition only when needed for large panels, maintaining compact dimensions during normal operation to maximize production efficiency while providing full support capability when required.
Solution Approach 2:
The patent utilizes vertical or lateral adjustment dimensions to provide extended support capability without increasing the horizontal footprint. By moving the support function to another dimension, the system accommodates large panels while maintaining compact outlet section space for high productivity.
4Object-affected harmful factors
If automatic detection systems are added to monitor shelf occupancy, then the safety is improved, but the device complexity is worsened
Solution Approach 1:
The patent replaces complex mechanical monitoring systems with simpler optical or electronic sensors. These sensors use light or electromagnetic fields to detect panel presence and shelf occupancy, providing automatic safety monitoring with minimal mechanical components and reduced overall system complexity.
Solution Approach 2:
The detection system is designed to serve multiple functions: monitoring shelf occupancy, detecting panel position, and triggering alerts. This multi-functionality reduces the need for separate dedicated sensors for each function, thereby adding safety capabilities without proportionally increasing system complexity.
