Saddle Bag Mounting Bracket Latch for Secure Pin Retention

Solution Overview

Problem

Existing saddle bag mounting systems for wheeled transport devices lack a secure latching mechanism to ensure the saddle bag is positively retained on the mounting pins, leading to potential accidents during transport.

Innovation Solution

A saddle bag mounting bracket with a latch mechanism that includes a base plate, clamp lever, latch lever, pressure adjustment device, and pin clamps, allowing the clamp lever to be latched to the base plate, ensuring the saddle bag is securely attached to the mounting pins.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a latch mechanism is added to the saddle bag mounting bracket, then the reliability of saddle bag retention is improved, but the device complexity increases

Engineering Contradiction:

Improvesaddle bag retentionVSAvoidmounting bracket structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The latch lever is nested within the clamp lever structure, with the latch projection fitting into the latch opening. This integration allows the latching function to be incorporated into the existing clamp mechanism without requiring a completely separate latching system, thereby improving reliability while limiting the increase in overall device complexity

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The latch projection acts as an intermediary element between the clamp lever and the base plate. It provides a positive engagement feature that ensures reliable retention of the saddle bag, while the simple geometric shape of the projection and opening keeps the intermediary mechanism itself relatively simple

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If a latch mechanism is added to the saddle bag mounting bracket, then the security of saddle bag attachment is improved, but the ease of operation deteriorates

Engineering Contradiction:

Improvesaddle bag attachment securityVSAvoidlatching and unlatching process

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The latch lever is designed to be movable, allowing it to pivot between engaged and disengaged positions. This dynamic capability enables the user to easily switch between locked and unlocked states by simply moving the lever, maintaining ease of operation while providing secure attachment when engaged

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The latch projection is pre-positioned within the latch opening during the clamping operation. As the clamp lever closes, the latch projection automatically engages with the latch opening, providing preliminary securing action before the user needs to manually secure the bag, thereby simplifying the overall operation

Inventive Principle:

Principle #10Preliminary action

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution provides a secure attachment of the saddle bag to the wheeled transport device, preventing accidental detachment and reducing the risk of accidents by ensuring the bag remains firmly in place during use.

Implementation Method 1

An extension spring is retained in the spring cutout. One end of the extension spring is engaged with spring retention hole at the end of the spring cutout. The latch projection engages the latch tab.

AI summary

A saddle bag mounting bracket preferably includes a base plate, clamp lever, a latch lever, a pressure adjustment device, a first pin clamp and a second pin clamp. The clamp lever is slidably engaged with the base plate. The latch lever is pivotally retained on one end of the clamp lever and biased with an extension spring. The latch lever includes a finger release, such that clamp lever may be unlatched from a latch tab extending from the base plate. One end of the pressure adjustment device is adjustably connected to the second pin clamp and an opposing end is pivotally connected to the clamp lever. The first and second pin clamps lock the base plate into first and second pins extending from a motorcycle or the like, when the clamp lever is latched. A key lock is preferably used to prevent the clamp lever from being unlatched.
