Solution Overview

Problem

Conventional tray loading systems require manual reconfiguration to change between loading regimes, leading to potential errors where good components are mistakenly loaded into bad trays, compromising the integrity of the loading process and potentially resulting in costly retesting or assembly of faulty components.

Innovation Solution

A tray loading system with a configurable bin and an electrically actuatable bin key that automatically switches between operating modes based on the presence of trays, ensuring that only appropriate trays are loaded, preventing good components from being mistakenly loaded into bad trays.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual reconfiguration is used to change between loading regimes, then the system can be reconfigured, but errors occur where good components are mistakenly loaded into bad trays

Engineering Contradiction:
Improveability to change between loading regimesVSAvoidintegrity of loading process
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The bin key assembly automatically switches between first and second configurations based on the presence or absence of trays in the tray loading bin, eliminating manual reconfiguration. The system self-adjusts by detecting tray presence and autonomously changing the bin key position to prevent loading errors

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system uses feedback from tray presence detection to automatically control bin key positioning. When trays are present, the bin key is positioned to allow loading; when trays are absent, the bin key switches to prevent loading, ensuring the system adapts based on real-time conditions

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If manual reconfiguration is required, then system flexibility is maintained, but costly retesting and assembly of faulty components may result

Engineering Contradiction:
Improveloading regime flexibilityVSAvoidretesting and assembly time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The bin key assembly proactively switches to the appropriate configuration before loading errors can occur. By automatically positioning the bin key based on tray presence, the system prevents faulty component assembly and eliminates the need for costly retesting

Inventive Principle:
Principle #10Preliminary action

3Productivity

If the bin key is always accessible, then loading operations are efficient, but good components may be mistakenly loaded into bad trays

Engineering Contradiction:
Improveloading operation efficiencyVSAvoidcomponent segregation integrity
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The bin key assembly dynamically changes its accessibility based on operating conditions. It automatically transitions between accessible and inaccessible states in response to tray presence, allowing the system to optimize between productivity and reliability depending on the current loading regime

Inventive Principle:
Principle #15Dynamics
