Universal Weight Fork with Interchangeable Adapters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handling tools for button-shaped test weights require multiple sizes and are cumbersome to use, especially for weights above 500 grams, posing challenges in precision and ease of handling due to the need for different tools and increased risk of damage or contamination.
Innovation Solution
A versatile handling tool with two fork ends of different nominal widths and interchangeable adapters, allowing for the secure handling of four different test weights without the need for multiple tools, featuring cup-shaped indentations for a form-fit grip and a metal core encased in plastic for protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate weight forks are used for different test weights, then each test weight can be handled with a precisely matched tool, but the device complexity increases and the ease of operation decreases due to needing to manage multiple tools
Solution Approach 1:
The weight fork is designed with a universal structure that can handle multiple test weights through interchangeable adapters. The main fork body remains constant while adapters with different nominal widths are attached to accommodate various button diameters, allowing one tool to perform multiple functions that previously required separate tools for each weight size.
Solution Approach 2:
The handling tool is segmented into a main fork body and separate adapter components. Each adapter is designed for a specific button diameter range and can be independently attached or removed from the fork ends. This segmentation allows the system to adapt to different test weights without requiring completely different tools for each weight size.
2Manufacturing precision
If multiple separate weight forks are used for different test weights, then each test weight can be handled precisely, but the ease of operation worsens due to increased user experience demands and tool management
Solution Approach 1:
The handling tool incorporates dynamic adaptability through interchangeable adapters that can be quickly attached and removed from the fork ends. This allows the tool to dynamically adjust its nominal width to match the specific test weight being handled, maintaining precision while simplifying operation since the user works with a single fork body and only needs to swap adapters when changing weight sizes.
3Manufacturing precision
If multiple separate weight forks are used, then each tool can be optimized for its specific weight, but the loss of time increases due to needing to switch between different tools
Solution Approach 1:
The system prepares multiple adapters in advance, each optimized for specific button diameter ranges. These adapters are kept ready for quick attachment to the fork ends, eliminating the need to switch between entirely different tools. The preliminary preparation of specialized adapters maintains precision handling while significantly reducing the time loss associated with tool switching.
4Device complexity
If a single handling tool is used for multiple test weights, then the device complexity decreases, but the manufacturing precision may worsen due to the need to accommodate different sizes
Solution Approach 1:
The adapters serve as intermediary components between the standardized fork body and the various test weight buttons. Each adapter is precisely manufactured to match specific button diameter ranges, while the fork body provides a universal mounting structure. This intermediary approach allows a single fork design to maintain high precision across multiple weight sizes without requiring custom-fitted tools for each weight.

AI summary
A weight box (10) having a plurality of test weights (12 to 18) comprises a weight fork (28), the opposite fork ends (32, 34) of which are associated with different test weights. The nominal widths of the fork ends can be reduced using individual adapters.
