Handheld Clamping Force Device with Interchangeable Grips
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current portable handheld devices for measuring manual clamping force are not universally adaptable, leading to uncomfortable use and inaccurate measurements for different users, as they are not ergonomically suited to various hand sizes, necessitating the use of multiple devices and increasing costs.
Innovation Solution
A portable handheld device with a force measuring body and interchangeable grips that can be easily attached and detached, allowing for size adjustments in length, width, and thickness to fit different hand sizes, providing a more ergonomic and accurate measurement experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-size force measuring device is used, then the device structure is simple, but it cannot adapt to different hand sizes leading to uncomfortable use and inaccurate measurements
Solution Approach 1:
The device is divided into two separable components: a force measuring body and interchangeable grips. The grip can be detached and replaced to adapt to different hand sizes, while the body remains unchanged. This segmentation allows the device to maintain measurement functionality while gaining adaptability through component replacement.
Solution Approach 2:
The force measuring body is designed to work with multiple types of grips, creating a universal system where one body can serve multiple users with different hand sizes. The interchangeable grip design enables a single device to perform the same measurement function across different users, eliminating the need for multiple specialized devices.
2Ease of operation
If multiple devices are used for different users, then each user gets a customized fit, but the cost increases and measurements over time become inaccurate
Solution Approach 1:
The device system is designed so that one force measuring body can be paired with multiple grips to accommodate different users. This universal design allows a single base device to serve multiple users with different hand sizes, eliminating the need to purchase multiple separate devices while maintaining ergonomic fit for each user.
3Measurement precision
If the device size is not adapted to the hand size, then the device structure remains simple, but the clamping force measurements become inaccurate
Solution Approach 1:
By separating the grip from the force measuring body, the system allows selective replacement of the grip component to match different hand sizes. This segmentation enables precise measurements for each user without requiring complex reconfiguration of the entire device, as only the grip portion needs to be changed.
