Solution Overview

Problem

Current electronic devices, such as robots, lack the ability to accurately analyze and predict movements of objects in their environment due to the failure to consider relationships between multiple objects, leading to potential collisions and inaccurate situation analysis.

Innovation Solution

An electronic apparatus equipped with a camera, memory, and processor that identifies attribute information and environment information to determine the relationship between objects, controlling its traveling state based on context, danger levels, and predicted movements, and operates in various modes such as protection, low-noise, monitoring, and private modes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the electronic apparatus considers relationships between multiple objects and their attributes, then the accuracy of situation analysis and prediction is improved, but the computational complexity and processing time increase

Engineering Contradiction:
Improveaccuracy of situation analysisVSAvoidcomputational complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system segments the environment into multiple objects with distinct attribute profiles (static/dynamic, movable/non-movable). By dividing the complex scene into discrete object entities with specific attributes, the system can analyze relationships between objects without overwhelming computational burden, resolving the contradiction between analysis accuracy and computational complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary classification of objects by their attributes (static/dynamic, movable/non-movable) before conducting relationship analysis. This pre-processing step organizes data structures in advance, enabling efficient prediction of object interactions without requiring complex real-time computations, thus improving accuracy while managing computational load

Inventive Principle:
Principle #10Preliminary action

2Reliability

If the electronic apparatus predicts future movements of objects based on relationships, then collision avoidance capability is improved, but the response time and processing delay increase

Engineering Contradiction:
Improvecollision avoidance capabilityVSAvoidprocessing delay
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system predicts future positions of dynamic objects by extrapolating their current movement trends and relationships with static objects. By performing prediction based on pre-established attribute relationships rather than real-time complex simulations, the system achieves reliable collision avoidance while minimizing processing delay

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses simplified prediction models that skip detailed physical simulations and directly calculate likely future positions based on object attributes and current states. This approach rushes through the prediction process efficiently, providing timely collision avoidance decisions without excessive processing delays

Inventive Principle:
Principle #21Skipping (Rushing through)

3Adaptability or versatility

If the electronic apparatus identifies and responds to multiple context types, then the adaptability to different situations is improved, but the system complexity and control difficulty increase

Engineering Contradiction:
Improveadaptability to different situationsVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system employs a universal context identification framework that handles multiple situation types (collision risk, private space, dangerous objects, protected objects) through a single integrated process. This multi-functional approach improves adaptability to different situations while avoiding the complexity of separate specialized systems for each context type

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

Solution Approach 2:

The system dynamically adjusts its response based on identified context types, transitioning between different operational modes (avoidance, monitoring, protection). This dynamic adaptation allows the system to handle diverse situations efficiently without requiring complex static control structures for each possible scenario

Inventive Principle:
Principle #15Dynamics
