Solution Overview

Problem

There is a need for a portable and secure solution to store multiple key fobs, which are often lost or misplaced due to their small size and lack of organized storage options.

Innovation Solution

A multiple key fob holder comprising a base, a cover, a master fastener, and a cord loop, where the base and cover form an enclosed containment structure that can be secured in a closed or open position, with elastic holsters and a coin purse for key fob and currency storage, and a cord loop that can be positioned internally or externally.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If key fobs are stored in a pocket or bag without dedicated storage, then portability is maintained, but key fobs are easily lost or misplaced due to lack of organized storage

Engineering Contradiction:
Improvekey fob retentionVSAvoidstorage structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The holder is divided into multiple functional segments: a base with elastic holsters for key fob storage, a coin purse for currency, and a cover with card pockets. This segmentation allows each component to serve a specific purpose, organizing multiple items separately to prevent loss while maintaining overall portability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The coin purse is nested within the base of the holder, and card pockets are integrated into the cover. This nesting approach maximizes space utilization within the compact structure, providing organized storage for multiple item types without significantly increasing the overall device size.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If a compact holder structure is used, then portability is improved, but access to stored items becomes less convenient

Engineering Contradiction:
Improveitem accessVSAvoidholder size
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The cover is designed to rotate relative to the base, transitioning between open and closed positions. This dynamic mechanism allows quick access to stored items by simply rotating the cover open, while maintaining a compact closed structure for portability. The elastic holsters also provide dynamic adjustment to accommodate different key fob sizes.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Different regions of the holder provide different access characteristics: the elastic holsters offer immediate access when the cover is opened, the coin purse provides controlled access through its opening, and the card pockets offer quick visual identification and retrieval. This local differentiation optimizes access efficiency for each item type within the compact structure.

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If multiple storage compartments are added, then organization capability is improved, but device complexity increases

Engineering Contradiction:
Improvestorage capacityVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The holder is designed as a multi-functional device that can store various item types: key fobs in elastic holsters, currency in the nested coin purse, and cards in cover pockets. This universal design allows a single device to replace multiple separate storage items, enhancing versatility while maintaining relatively simple construction through the use of basic components like elastic bands, fabric pockets, and rotational joints.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The multiple key fob holder is a case which stores a plurality of key fobs. The multiple key fob holder comprises a base, a cover, a master fastener, and a cord loop. The base and the cover form an enclosed containment structure within which the plurality of key fobs are contained. The base and the cover attach such that the cover rotates relative to the base. The master fastener attaches the base to the cover such that the containment structure can be secured in a closed position and unsecured to form an open position. The cord loop is a loop structure positioned at a location selected from the group consisting of: 1) the interior of the containment structure when the multiple key fob holder is in a closed position; and, 2) the exterior of the containment structure when the multiple key fob holder is in an open position.
