Solution Overview

Problem

Existing weightlifting brackets and hooks, such as J-cups, face issues with safety and strength, particularly under high usage and varying user sizes, leading to potential failure and premature deformation.

Innovation Solution

A bracket assembly with a back plate, clasp member, and pin configuration that includes an enlarged pin head welded to the back plate, providing enhanced mechanical strength and adjustable positioning for secure beam engagement, along with a cover to protect users from sharp edges.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional J-cup brackets are used with pin insertion through apertures, then assembly is simple, but strength and reliability are insufficient under high usage loads

Engineering Contradiction:

Improvebracket strengthVSAvoidbracket structure

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The bracket is divided into multiple components: a back plate for mounting, a clasp member for beam engagement, and a pin for securing. This segmentation allows each component to be optimized for its specific function while maintaining overall structural strength and reliability under high usage loads.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The clasp member combines multiple functions: it provides the channel for beam reception, the engagement surfaces for securing the beam, and integration points for the pin. This merging of functions into a single component enhances strength while reducing the number of separate parts needed.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If brackets are designed for adjustable positioning to accommodate different user sizes and exercises, then versatility improves, but structural integrity may be compromised

Engineering Contradiction:

Improveadjustable positioningVSAvoidbracket reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The bracket incorporates adjustable positioning capabilities through the pin system that can be positioned at multiple locations along the back plate, allowing adaptation to different user sizes and exercises. The dynamic adjustability is achieved without compromising reliability through the robust welded construction and engineered engagement surfaces.

Inventive Principle:

Principle #15Dynamics

3Productivity

If repeated usage and high repetition rates are applied to brackets, then productivity increases, but brackets deform and require premature replacement

Engineering Contradiction:

Improverepetition rateVSAvoidbracket lifespan

Core Design Contradiction:

ProductivityVSDuration of action of stationary object

Solution Approach 1:

The bracket design incorporates engineered features such as the clasp member geometry and pin engagement system that anticipate and distribute repeated loading forces. This beforehand cushioning through proper structural design prevents deformation under high repetition rates and extends bracket lifespan while maintaining productivity.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

4Force

If bracket components have sharp edges for secure engagement, then holding capability improves, but user safety is compromised

Engineering Contradiction:

Improveholding capabilityVSAvoidsharp edges

Core Design Contradiction:

ForceVSObject-affected harmful factors

Solution Approach 1:

The bracket design applies different surface qualities to different locations: engagement surfaces have precise geometric features for secure holding capability, while user-accessible surfaces are finished to eliminate sharp edges. This local differentiation maintains forceful engagement while ensuring user safety.

Inventive Principle:

Principle #3Local quality

AI summary

A bracket assembly includes a back plate with outer and inner sides and a pin opening extending therethrough. A clasp member has an extending portion and an encasing portion extending from the extending portion. The extending and encasing portions and the inner side of the body define a channel configured to receive a rack beam. A pin seated in the pin opening has a shank, and a head at the outer side of the back plate. The shank extends through the opening into the channel. The shank is configured to engage the rack beam within the channel. The head is welded to the outer side of the back plate. An extension member defines a support surface and includes pair of substantially J-shaped plates and a cover nested with the plates such that it forms the entire support surface and is substantially flush with sides of the substantially J-shaped plates.
