Solution Overview

Problem

Users of infrequently used vehicle interface devices, such as power outlets, face difficulties in accessing guidance on their usage methods due to digitized manuals that require downloading and navigating through lengthy documents.

Innovation Solution

A two-dimensional code is printed on a member near each interface device, encoding digital data that directs users to the electronic manual, allowing them to access guidance via a portable terminal, which can acquire or output the manual as needed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If digital data is encoded in a two-dimensional code printed on a member near the interface device, then users can promptly access relevant information in the electronic manual, but the device complexity increases due to the addition of coding and printing components

Engineering Contradiction:
Improvetime to access manualVSAvoidsystem complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The patent creates a simplified copy of the manual access function by encoding essential information (URL, manual ID, or page numbers) into a two-dimensional code that can be optically read. This copy contains only the necessary data to retrieve the full manual, eliminating the need for users to navigate through the entire document while adding minimal system complexity through standard coding and printing capabilities.

Inventive Principle:
Principle #26Copying

2Reliability

If the electronic manual is stored locally in the portable terminal, then users can access guidance without internet connection, but the initial download time and data usage increase

Engineering Contradiction:
Improveaccess reliabilityVSAvoiddownload time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary action by pre-storing the two-dimensional code with encoded access information in the portable terminal. This allows the terminal to quickly retrieve and display manual information without requiring full downloads each time, while still maintaining the option to store complete manuals locally for offline access when needed.

Inventive Principle:
Principle #10Preliminary action

3Loss of time

If the two-dimensional code contains complete manual information, then no internet connection is needed, but the code size and printing area increase significantly

Engineering Contradiction:
Improveinternet dependencyVSAvoidprinting area
Core Design Contradiction:
Loss of timeVSArea of stationary object

Solution Approach 1:

The patent extracts only the essential information needed to access the manual (URL, manual ID, or specific page numbers) and encodes it into the two-dimensional code. This extraction approach eliminates unnecessary data from the code itself, keeping the printing area small while still enabling complete manual access through internet connection or local storage retrieval.

Inventive Principle:
Principle #2Taking out (Extraction)

4Loss of information

If users must navigate through lengthy documents to find interface device instructions, then comprehensive manual coverage is maintained, but the ease of operation deteriorates

Engineering Contradiction:
Improvemanual completenessVSAvoidmanual navigation ease
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent adds a new dimension to manual access by incorporating direct navigation data (specific page numbers or section identifiers) into the two-dimensional code. This allows users to jump directly to the relevant interface device instructions rather than searching through the entire manual, maintaining comprehensive coverage while dramatically improving ease of operation through targeted access.

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