Solution Overview

Problem

Existing golf car sand bottle mounting arrangements lack secure retention and feedback, making it difficult to determine if the sand bottle is properly secured, as they rely on gravity and lack a locking mechanism.

Innovation Solution

A sand bottle assembly with a mounting bracket that features an extension portion with a raised sidewall and an annular protrusion, providing an interference fit and positive feedback upon secure installation, ensuring the bottle is locked in place.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the mounting bracket surrounds the bottle entirely in an installed position, then the bottle is securely retained, but it becomes difficult to access how much sand is available in the bottle

Engineering Contradiction:
Improvesecure retentionVSAvoidaccess to sand quantity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The mounting bracket is segmented into two functional zones: an engaging portion that secures the bottle and a platform portion that leaves the bottle partially accessible. This segmentation allows the bracket to provide secure retention while still permitting users to observe sand quantity through the partially exposed bottle body.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the sand bottle is placed into the installed position by dropping it vertically onto a horizontal platform, then installation is simple, but there is no gripping or locking action and no feedback to the user that the bottle is securely retained

Engineering Contradiction:
Improveinstallation simplicityVSAvoidsecure retention with feedback
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The engaging portion of the mounting bracket is designed to provide tactile feedback to the user during installation. As the bottle is dropped vertically onto the platform, the engaging portion grips the bottle body and provides a noticeable locking action that signals to the user that the bottle is securely retained in the installed position.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The mounting bracket's engaging portion automatically grips and locks the bottle during the dropping installation process without requiring additional user actions. The structural design of the engaging portion causes it to naturally engage with the bottle body and provide securing force as the bottle settles onto the platform.

Inventive Principle:
Principle #25Self-service

AI summary

A sand bottle assembly on a golf car includes a bottle and a mounting bracket. The bottle is defined by a longitudinal hollow body having a bottom portion and a top portion. The hollow body defines a vertical axis. A spout is formed at the top portion and is adapted to dispense sand contained in the hollow body. An extension portion is disposed along a sidewall of the hollow body. The extension portion includes a raised sidewall portion. The mounting bracket is adapted to be connected to the golf car and matingly receive the extension portion of the bottle in an installed position. The mounting bracket defines an engaging portion adapted to engage and retain the raised sidewall of the extension portion in a secure position along the vertical axis in the installed position.
