Solution Overview

Problem

Existing overhead conveyor pocket systems require fixed-location unloading stations for opening, limiting flexibility in unloading locations.

Innovation Solution

The system incorporates a remotely controllable actuating mechanism with a position-determining unit and control unit that allows the pocket to be opened and closed at any position along the conveyor system, using radio signals to activate actuators like solenoids for flexible unloading.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If fixed-location unloading stations are used to open pockets, then the opening mechanism is simple and reliable, but the flexibility in unloading locations is limited

Engineering Contradiction:
Improveflexibility in unloading locationsVSAvoidcomplexity of actuating mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the pocket opening mechanism controllable at any position along the conveyor line rather than at fixed locations. The actuating means can be triggered at variable positions based on delivery requirements, transforming a static fixed-location opening system into a dynamic flexible-opening system. This resolves the contradiction by enabling adaptability in unloading locations while managing device complexity through controlled actuation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent replaces the traditional mechanical fixed-location opening mechanism with an electronically controlled actuating system. Instead of relying on fixed mechanical triggers at specific conveyor stations, the system uses actuators (such as solenoids or motors) that can be remotely controlled to open pockets at any desired position. This substitution enables flexible unloading locations while the electronic control system manages the complexity of the actuating mechanism.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If remote control capability is added to open pockets at any position, then flexibility in unloading locations is improved, but the device complexity increases

Engineering Contradiction:
Improveflexibility in unloading locationsVSAvoidcomplexity of control system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the universality principle by designing the actuating means to perform multiple functions: it can open pockets at any position along the conveyor line, accommodate different control methods (manual or automated), and work with various pocket types. This multi-functional design enables flexible unloading locations while consolidating control capabilities into a universal system that manages complexity through versatility rather than multiple specialized systems.

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

Solution Approach 2:

The patent introduces a control unit as an intermediary between the remote control signal and the actuator. This intermediary processes control signals, determines the appropriate opening position, and activates the actuator accordingly. The control unit acts as a mediator that manages the complexity of the remote control system by centralizing the decision-making logic and separating the control signal reception from the physical actuation, thereby enabling flexibility while organizing system complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If the pocket can be opened during travel at any position, then unloading flexibility is improved, but the reliability of the opening mechanism may deteriorate

Engineering Contradiction:
Improveflexibility in unloading locationsVSAvoidreliability of opening mechanism
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies the preliminary action principle by preparing the pocket opening mechanism in advance during the loading phase. The actuating means is pre-configured and tested before the pocket enters service, ensuring that when opening is required at any position during travel, the mechanism is already ready to execute reliably. This preliminary preparation maintains reliability while enabling flexible unloading locations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements the self-service principle by designing the actuating means to automatically execute the opening action once triggered, without requiring manual intervention during the opening process. The control unit receives the opening signal and automatically activates the actuator to open the pocket at the desired position. This automated self-service mechanism maintains reliability by eliminating human error during operation while enabling flexible unloading at any position along the conveyor line.

Inventive Principle:
Principle #25Self-service
