Solution Overview

Problem

Existing in-vehicle systems inefficiently manage storage capacity by retaining software for disconnected hardware, leading to wasted storage space.

Innovation Solution

An in-vehicle unit with detection, communication, and control sections that install software for connected hardware and perform compression or deletion processing for disconnected hardware to optimize storage usage, allowing for efficient reuse of storage capacity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If software is retained for disconnected hardware, then hardware reconnection can be quickly supported, but storage capacity is wasted

Engineering Contradiction:

ImproveHardware reconnection supportVSAvoidStorage capacity utilization

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent applies dynamics by making the software storage state changeable based on hardware connection status. Software is dynamically retained when hardware is connected and dynamically deleted when hardware is disconnected, allowing the system to adapt its storage behavior to current operational needs rather than maintaining a static storage approach

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent implements feedback by monitoring the connection status of hardware and using this information to control software retention decisions. The detection section continuously provides feedback on hardware connection state to the control section, which then adjusts software storage accordingly, creating a closed-loop system that optimizes storage based on actual usage requirements

Inventive Principle:

Principle #23Feedback

2Quantity of substance

If compression processing is performed on software, then storage capacity is optimized, but processing time and computational resources are consumed

Engineering Contradiction:

ImproveStorage capacityVSAvoidCompression processing time

Core Design Contradiction:

Quantity of substanceVSLoss of time

Solution Approach 1:

The patent applies preliminary action by performing compression processing in advance when software is first installed or when hardware is disconnected, rather than waiting until storage capacity becomes critical. This proactive approach ensures storage optimization is achieved before storage constraints become problematic, reducing the need for urgent processing later

Inventive Principle:

Principle #10Preliminary action

AI summary

An in-vehicle system enables retrofitted hardware to be used in cases in which predetermined hardware has been connected to an in-vehicle unit by performing processing to obtain an application corresponding to the predetermined hardware from a server and install the application in the in-vehicle unit. In cases in which the retrofitted hardware has been disconnected from the in-vehicle unit, the in-vehicle system also performs at least one type of processing out of processing to compress or processing to delete the application corresponding to the retrofitted hardware that has been disconnected.
