Quick Release Weight Retaining Device Ejector Mechanism

Solution Overview

Problem

Existing weight releaser devices are large, bulky, and heavy, making them difficult to set up and reset alone, and often cause jerking of the weight bar due to angled designs, limiting user flexibility during exercises.

Innovation Solution

A quick release weight retaining device with a grapple and retainer system that allows for secure engagement and rapid release, featuring a seat and ejector mechanism that disengages when the weight is relieved, preventing bar jerking and enabling a greater range of motion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If current weight releaser devices use a bulky structure with an angled surface for release, then the device can securely hold weights, but the device becomes large and heavy making it difficult to set up and reset alone

Engineering Contradiction:

Improveweight securing capabilityVSAvoidsetup and reset difficulty

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The device is divided into separate functional components: a grapple for securing the bar, a retainer for holding the weight, and a floor-contacting member for release. This segmentation allows each component to be optimized independently and reduces the overall size while maintaining functionality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of using a large angled surface that contacts the floor for release, the invention uses a small ejector surface on the floor-contacting member that pushes against the bar to release it. This inverted approach eliminates the need for large angled surfaces and reduces device size.

Inventive Principle:

Principle #13The other way round (Inversion)

2Reliability

If current weight releaser devices use a bulky structure with an angled surface for release, then the device can securely hold weights, but the device becomes heavy adding to the weight the user must lift

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSWeight of moving object

Solution Approach 1:

The device is divided into separate functional components: a grapple for securing the bar, a retainer for holding the weight, and a floor-contacting member for release. This segmentation allows each component to be optimized independently and reduces the overall size while maintaining functionality.

Inventive Principle:

Solution Approach 2:

Instead of using a large angled surface that contacts the floor for release, the invention uses a small ejector surface on the floor-contacting member that pushes against the bar to release it. This inverted approach eliminates the need for large angled surfaces and reduces device weight.

Inventive Principle:

Principle #13The other way round (Inversion)

3Ease of operation

If current weight releaser devices use an angled portion for release, then the device can release weights, but the angled portion causes the bar to jerk when not rapidly lowered

Engineering Contradiction:

Improveweight release capabilityVSAvoidbar jerking

Core Design Contradiction:

Ease of operationVSObject-generated harmful factors

Solution Approach 1:

Instead of using a large angled surface that contacts the floor for release, the invention uses a small ejector surface on the floor-contacting member that pushes against the bar to release it. This inverted approach eliminates the need for large angled surfaces and reduces device size.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The harmful angled portion is completely removed from the design. The release function is achieved through a different mechanism involving the ejector surface pushing against the bar, eliminating the source of bar jerking while maintaining release capability.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A quick release weight retaining device may include a grapple which may be removably engaged to a retainer. The grapple may include a seat and an ejector, and the retainer may include an arm. The grapple may be coupled to objects, such as a lifting bar, preferably via a securement fastener. The retainer may be coupled to objects, such as weight plates and the like, via a retainer body and a weight saddle. The arm may rest in the seat and be maintained therein by a desired weight, such as the weight of the weight saddle. When the weight is relieved from the retainer, such as by the weight saddle resting on a ground surface, the ejector may force the arm out of the seat thereby disengaging the grapple and retainer.
