Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing electronic component connection systems make it difficult to visually confirm the connection status between terminals, especially in compact designs where size reduction is necessary for vehicle mountability.

Innovation Solution

An accommodation confirming structure that generates a sound upon successful insertion of an electronic component into an accommodation chamber, using a mechanism with a projection body and an inclinable body that engage to produce an audible signal when the component is fully accommodated, allowing for easy confirmation of terminal connections without increasing device size.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Difficulty of detecting and measuring

If a connection status confirmation mechanism is added to visually confirm terminal connections, then the confirmation capability is improved, but the device size increases

Engineering Contradiction:

Improveconfirmation capabilityVSAvoiddevice size

Core Design Contradiction:

Difficulty of detecting and measuringVSVolume of stationary object

Solution Approach 1:

The patent merges the confirmation mechanism with the existing accommodation chamber structure. The elastic member and pressing portion are integrated into the housing walls, combining the confirmation function with the structural components already present in the device, thereby avoiding additional space requirements.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The confirmation mechanism is nested within the accommodation chamber structure. The elastic member is disposed within the accommodation chamber wall, and the pressing portion is formed as part of the housing structure, allowing the confirmation function to be embedded within the existing device footprint without increasing overall size.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Volume of stationary object

If the accommodation chamber is made compact for vehicle mountability, then the mountability is improved, but the confirmation of connection status becomes more difficult

Engineering Contradiction:

Improveaccommodation chamber sizeVSAvoidconnection status confirmation

Core Design Contradiction:

Volume of stationary objectVSDifficulty of detecting and measuring

Solution Approach 1:

The patent introduces an intermediary confirmation mechanism that translates the internal connection status into an external audible signal. The elastic member and pressing portion act as intermediaries that convert the mechanical state of terminal connection into a sound output, allowing confirmation without visual inspection and independent of chamber size.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces visual confirmation (mechanical/optical system) with acoustic confirmation. Instead of requiring visual inspection of terminal connections, the system uses sound generation through the elastic member and pressing portion to indicate connection status, enabling confirmation in compact spaces where visual access is limited.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A structure includes an accommodation chamber, an accommodation confirming mechanism, and an operation space of the accommodation confirming mechanism. The accommodation confirming mechanism includes a first and second accommodation completion sound generating body. The first accommodation completion sound generating body is a projection body. The second accommodation completion sound generating body is an inclinable body configured to be inclined by being pressed by the inserted electronic component. The second accommodation completion sound generating body includes a receiving portion configured to receive a pressing force from a pressing portion of the electronic component and a leap portion configured to climb over the first accommodation completion sound generating body and generates the accommodation completion sound with the first accommodation completion sound generating body at a time when the electronic component is inserted to the accommodation completion position.
