Solution Overview

Problem

Electronic devices lack the ability to effectively detect and analyze collisions, which can lead to damage or unintended usage, as they cannot determine the type of object collided with or perform appropriate functions based on the impact patterns.

Innovation Solution

An electronic device equipped with sensors and a processor that collects and analyzes sensing data to determine falling and collision patterns, identifies the type of object collided with, and performs preset functions accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If sensors are used to detect collision, then collision detection capability is improved, but the ability to determine object type and perform appropriate functions remains insufficient

Engineering Contradiction:
Improvecollision detection capabilityVSAvoidobject type identification and functional response
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The collision analysis process is segmented into multiple independent analysis stages: initial collision detection, object type determination, and functional response selection. Each stage processes specific sensing data independently, allowing the system to handle complex collision scenarios by breaking down the overall problem into manageable segments that can be addressed sequentially.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system transitions from simple collision detection (binary yes/no) to multi-dimensional collision analysis by incorporating object type classification and functional response determination. This adds new dimensions to the collision detection capability, transforming it from a single-function sensor system to a comprehensive collision management system that considers multiple factors simultaneously.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Measurement precision

If multiple sensing data are collected to determine collision patterns, then collision analysis accuracy is improved, but data processing complexity increases

Engineering Contradiction:
Improvecollision analysis accuracyVSAvoiddata processing complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system performs preliminary actions by pre-defining multiple object types and their corresponding characteristics before actual collision occurs. During collision analysis, the processor compares sensed data against these pre-established patterns, significantly reducing real-time processing complexity. This preliminary classification framework allows accurate collision analysis without requiring complex real-time computation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system creates simplified representations (copies) of complex collision scenarios by storing typical collision patterns and object type profiles in advance. During actual collision events, the processor matches sensed data against these stored patterns rather than performing full complex analysis, reducing computational burden while maintaining accuracy.

Inventive Principle:
Principle #26Copying
