Solution Overview

Problem

Existing work benches in machining centers are inflexible, leading to increased downtime due to the need for manual reconfiguration and limited ability to machine panels of different sizes and orientations, particularly when working on narrow faces parallel to the Y-direction.

Innovation Solution

The work bench features movable supporting and blocking members, motorized conveyor belts, and actuator systems that allow for dynamic reconfiguration and support of panels of varying dimensions, enabling machining of narrow faces in all positions without interrupting machining processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the work bench uses fixed support elements and conveyor belts, then the structure is simple and stable, but it cannot adapt to panels of different sizes and orientations, increasing downtime for reconfiguration

Engineering Contradiction:
Improveadaptability to different panel sizes and orientationsVSAvoidcomplexity of movable support elements and conveyor groups
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the support elements and conveyor groups movable rather than fixed. The support elements can move along the Y-axis to adjust their positions, and the conveyor groups can move along the X-axis and raise/lower to adapt to different panel configurations. This dynamic capability allows the work bench to accommodate panels of various sizes and orientations without manual reconfiguration, directly resolving the technical contradiction between adaptability and device complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements universality by designing a multi-functional work bench where the same movable support elements and conveyor groups can serve multiple functions: supporting panels during machining, transporting panels along the X-axis, and adjusting to different panel orientations. This eliminates the need for separate fixed structures for each function, achieving versatility while controlling complexity through integrated design.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Manufacturing precision

If the work bench is configured for specific panel dimensions, then machining precision is maintained, but downtime increases due to manual reconfiguration for different panel sizes

Engineering Contradiction:
Improvemachining precisionVSAvoiddowntime for reconfiguration
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-programming the positions and configurations of the movable support elements and conveyor groups for different panel types. Before machining begins, the system can automatically configure the work bench for the specific panel dimensions and orientation required, eliminating manual reconfiguration time. The control system stores preset configurations that can be quickly activated, maintaining machining precision while minimizing downtime.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The dynamic movement capabilities of the support elements and conveyor groups enable rapid reconfiguration between different panel configurations. The system can transition from one preset configuration to another during panel changeover, maintaining machining precision through controlled movement while significantly reducing the time required compared to manual reconfiguration of fixed structures.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If the panel is positioned at fixed locations on the work bench, then support and blocking are simplified, but the machining group cannot access narrow faces parallel to the Y-direction

Engineering Contradiction:
Improveease of panel support and blockingVSAvoidability to machine narrow faces in all positions
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent resolves this contradiction by making the support elements movable along the Y-axis rather than fixed at specific locations. This allows the support elements to dynamically adjust their positions to accommodate panels in various orientations, including those with narrow faces parallel to the Y-direction. The machining group can access narrow faces because the support elements can be repositioned out of the way or adjusted to provide clear access paths.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The work bench is segmented into multiple independently movable support elements rather than a single fixed support structure. This segmentation allows individual support elements to be positioned and adjusted independently to accommodate different panel configurations, providing both ease of operation through modular control and versatility in accessing narrow faces at various positions.

Inventive Principle:
Principle #1Segmentation

4Device complexity

If manual loading and unloading is used, then the work bench structure is simpler, but productivity decreases due to operator involvement and slower cycle times

Engineering Contradiction:
Improvesimplicity of work bench structureVSAvoidproductivity of machining center
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent applies self-service by equipping the work bench with automatic conveyor groups that can independently transport panels along the X-axis and position them for machining without operator intervention. The conveyor groups can automatically raise and lower, and the movable support elements can self-adjust to panel positions, enabling the work bench to service itself during panel loading, unloading, and repositioning operations, thereby increasing productivity while maintaining reasonable structural complexity.

Inventive Principle:
Principle #25Self-service
