Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional weight training devices with stacked counterweight elements tend to become loose during use, making them inconvenient and unsafe.
Innovation Solution
A weight training device design featuring a holding element, counterweight elements, and fastening elements with locking members and position limiting slots, where the fastening elements are positioned elastically to prevent relative rotation and ensure stable connections between elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If counterweight elements are stacked in series by locking, then the device can be customized for different weights and saved purchase cost, but the locking structure becomes loose during use
Solution Approach 1:
The fastening element is inserted through the locking member and into the position limiting slot, creating a nested structure where the fastening element is contained within the locking mechanism. This nested configuration ensures the fastening element remains securely positioned while allowing weight customization by adding or removing counterweight elements.
Solution Approach 2:
The fastening element acts as an intermediary component between the locking member and the position limiting slot. It mediates the connection by physically bridging these two structures, preventing the locking member from becoming loose while maintaining the ability to assemble and disassemble counterweight elements for customization.
2Ease of operation
If a simple locking structure is used, then the device is easy to assemble and disassemble, but the connection becomes loose during use
Solution Approach 1:
The connection system is segmented into distinct functional components: the locking member for initial engagement, the fastening element for securing, and the position limiting slot for final positioning. This segmentation allows each component to perform its specific function effectively, maintaining both ease of assembly and connection stability.
Solution Approach 2:
The locking member performs a preliminary locking action first, followed by the fastening element being inserted to secure the connection. This preliminary action sequence ensures that the basic locking is established before the additional securing measure is applied, maintaining both ease of operation and stability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

AI summary
A weight training device, comprising a holding element, a first counterweight element, and a first fastening element. The holding element has a locking member on one end, and one side of the holding element is provided with at least one first upper positioning member. The first counterweight element has a first locking member and a first position limiting slot on one end, wherein the first locking member is for locking the locking member of the holding element. One end of the first fastening element is position limited in the first position limiting slot in an elastic manner, and another end of the first fastening element has a first stopper for fixing the first upper positioning member to prevent a relative rotation between the holding element and the first counterweight element, so that a stable connection can be formed between the holding element and the first counterweight element for easy use, and the safety use can be ensured.
