Solution Overview

Problem

Existing robots struggle to accurately grip objects without precise recognition of distance and shape, requiring complex and costly sensors, and often necessitate trial and error for successful gripping.

Innovation Solution

An electronic apparatus using a gripper controlled by a neural network model that processes images from a camera to provide movement and rotation information, allowing the gripper to position itself adjacent to the object without precise distance or shape recognition, utilizing a simple camera and eliminating the need for expensive sensors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If accurate recognition of distance and shape is used for gripping, then gripping precision is improved, but device complexity and cost increase due to requiring complex sensors

Engineering Contradiction:
Improvegripping precisionVSAvoidsensor complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical sensing systems (depth sensors, stereo cameras, LiDAR) with a simple 2D camera combined with neural network-based image processing. The neural network analyzes 2D images to infer 3D spatial relationships and gripper positioning, substituting physical sensing complexity with computational intelligence.

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

Solution Approach 2:

The patent introduces an intermediary neural network processing system between the simple camera and the gripping control. This intermediary layer processes 2D images to generate movement and rotation information, acting as a mediator that bridges the gap between simple sensing and complex gripping tasks without requiring complex sensors.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If complex sensors are used for accurate object recognition, then gripping accuracy is improved, but cost increases

Engineering Contradiction:
Improveobject recognition accuracyVSAvoidsensor cost
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent employs a inexpensive 2D camera instead of expensive specialized sensors (depth sensors, stereo cameras, LiDAR). While the camera itself is simple and low-cost, the neural network processing provides the necessary intelligence to achieve accurate gripping, effectively replacing expensive sensing hardware with affordable imaging hardware plus software intelligence.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent substitutes expensive mechanical/optical sensing systems with a computationally-based solution using a simple camera and neural network. This replacement achieves similar or better performance while dramatically reducing hardware cost.

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

3Adaptability or versatility

If trial and error method is used for gripping, then adaptability is improved, but time consumption increases

Engineering Contradiction:
Improvegripping adaptabilityVSAvoidgripping time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent performs preliminary action by pre-training the neural network on diverse object images and gripper positions. During actual operation, the already-trained neural network directly processes images to generate accurate movement and rotation commands, eliminating the need for real-time trial and error attempts.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback by continuously capturing images with the camera, processing them through the neural network to generate movement/rotation information, executing the commands, and repeating the cycle. This closed-loop feedback system enables accurate and adaptive gripping without trial-and-error waste.

Inventive Principle:
Principle #23Feedback
