Solution Overview

Problem

The manual removal of hard drives from static-shielding bags is labor-intensive and time-consuming due to the tightly wrapped nature of the bags, which hinders efficient handling and installation processes.

Innovation Solution

An automated de-bagging system comprising a robotic arm, a cutting nest assembly, and sensors that pick up, cut open, and remove the static-shielding bags from hard drives, utilizing a compartment with movable side-walls and a bottom to facilitate the process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual removal of hard drives from static-shielding bags is performed, then labor flexibility is maintained, but productivity is reduced and time consumption increases

Engineering Contradiction:
Improvede-bagging throughputVSAvoidautomation system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system segments the de-bagging process into distinct functional modules: a robotic arm for item handling, a cutting nest assembly with compartment for bag opening, and a bag gripper for bag manipulation. Each module performs a specific task, allowing the system to achieve high productivity through coordinated automation while keeping individual components relatively simple and maintainable.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The robotic arm serves multiple functions by sequentially performing item pickup, depositing into the compartment, and later pickup of unbagged items. The cutting assembly and bag gripper work together as a universal bag-opening mechanism that can handle different bagged items, reducing the need for specialized equipment for each step.

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

2Reliability

If static-shielding bags are tightly wrapped for protection, then protection effectiveness is improved, but ease of removal deteriorates

Engineering Contradiction:
Improveprotection effectivenessVSAvoidbag removal ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system performs preliminary action by positioning the bagged item in a dedicated compartment and using a bag gripper to pre-grab and hold the bag in place before cutting. This preliminary positioning and gripping ensures the tightly wrapped bag remains stable during the cutting operation, maintaining protection integrity while facilitating subsequent easy removal after cutting.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The cutting assembly extracts the bag opening function by precisely cutting the bag material at predetermined locations. This extraction of the opening function from manual manipulation allows the tightly wrapped protective bag to be cleanly opened without compromising its protective qualities during handling, while making removal straightforward after cutting.

Inventive Principle:
Principle #2Taking out (Extraction)

3Speed

If automated cutting and gripping mechanisms are introduced, then de-bagging speed increases, but device complexity increases

Engineering Contradiction:
Improvede-bagging speedVSAvoidmechanism complexity
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The system merges the cutting function and gripping function into a coordinated automated sequence within the cutting nest assembly. The bag gripper and cutting assembly work together as an integrated unit, with the gripper holding the bag while the cutting blade opens it, and the robotic arm coordinating both operations. This merging of functions into a single automated station achieves high de-bagging speed while consolidating complexity into one manageable module rather than分散 across multiple independent systems.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A de-bagging system includes a robot system with a robotic arm, a cutting nest assembly having a compartment including a first side-wall, and a second side-wall, and configured to receive a bagged item, a bag gripper movable relative to the first side-wall and the second side-wall, and a cutting assembly having a cutting blade. The cutting blade is slidably mounted in vicinity of the compartment. The robot system is configured to pick up a bagged item, to deposit the bagged item into the compartment, and to pick up an unbagged item from the compartment.
