Solution Overview

Problem

Inward-opening storage devices, such as console boxes for vehicles, face challenges in preventing small articles like coins and tickets from being inserted between the lid and cover members, as existing designs fail to effectively prevent insertion and retrieval due to gaps between these components.

Innovation Solution

A storage device with a comb-teeth-like fin member pivotally supported on the lid member, which meshes with recessed groove portions on the cover member, and an urging member to ensure sliding contact and prevent small articles from being inserted between the lid and cover members by creating a zigzag gap that inhibits insertion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a gap is formed between the cover member and the sweeping member, then the structure allows movement and assembly, but small articles can be inserted into the gap and cannot be retrieved

Engineering Contradiction:
Improveassembly easeVSAvoidsmall article insertion
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The fin member acts as an intermediary component between the lid member and cover member. It fills the gap that would otherwise allow small articles to be inserted, while still permitting the necessary movement and assembly operations. The fin member's tooth portions engage with recessed groove portions to prevent article insertion while maintaining functional movement.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If the fin member tooth portions are in sliding contact with the cover member groove portions, then small article insertion is prevented, but the device complexity increases

Engineering Contradiction:
Improvesmall article insertion preventionVSAvoidstructure complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The fin member is segmented into multiple tooth portions, and the cover member has corresponding recessed groove portions. This segmentation creates a comb-like structure that effectively prevents small articles from being inserted while maintaining relatively simple individual component designs. The segmented structure achieves complex functionality through simple repeated elements.

Inventive Principle:
Principle #1Segmentation

3Reliability

If an urging member is added to urge the fin member, then sliding contact is ensured, but the device complexity and manufacturing cost increase

Engineering Contradiction:
Improvesliding contact reliabilityVSAvoidcomponent quantity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The urging member is designed to utilize the existing movement of the lid member to automatically urge the fin member against the cover member. As the lid member moves between opened and closed positions, the urging member passively maintains contact through the mechanical interaction already present in the system, rather than requiring an active urging mechanism.

Inventive Principle:
Principle #25Self-service

AI summary

A storage device 1 includes: a case member 2; a lid member 3 configured to change between a closed position, an opened position, and a half-opened position; a fin member 4 configured to be pivotally supported on the second end portion 32 of the lid member 3; a cover member 5 configured to be positioned so as to be fixed relative to the case member 2, and to be disposed backward of the lid member 3 on the back side; and an urging member 80. When the lid member 3 changes between the half-opened position and the opened position, the projecting tooth portions 46 of the fin member 4 are in sliding contact with the recessed groove portions 55 of the cover member 5 by urging force of the urging member 80.
