Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If haptic effect data is stored in original form in memory or disk, then data accessibility and playback quality are maintained, but storage space occupancy increases significantly

Engineering Contradiction:
Improvestorage spaceVSAvoiddata accessibility
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The patent applies compression algorithms that transform haptic effect data from original high-resolution form to compressed low-resolution form, changing the data parameters (bit depth, sampling rate) to reduce storage space while maintaining acceptable playback quality through intelligent reconstruction techniques

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If haptic effect data is stored in accessible memory or disk space, then data can be easily retrieved and played back, but data security is compromised

Engineering Contradiction:
Improvedata retrievalVSAvoiddata security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent implements encryption algorithms that perform preliminary transformation of haptic effect data into encrypted form before storage, so that even if data is accessed unauthorized, it remains unintelligible without the decryption key, thus securing data while maintaining ease of retrieval for authorized users

Inventive Principle:
Principle #10Preliminary action

3Quantity of substance

If compression algorithms are applied to haptic effect data, then storage space is reduced, but data security requirements increase

Engineering Contradiction:
Improvestorage spaceVSAvoidencryption requirement
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent combines compression and encryption operations into an integrated processing pipeline, where compression is applied first to reduce data size, then encryption is applied to the compressed data, achieving both storage reduction and security enhancement without significantly increasing system complexity through modular design

Inventive Principle:
Principle #5Merging (Combining)
