Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single clasp mechanism is used to secure weight plates, then disassembly speed is improved, but stability deteriorates due to easy detachment during intense exercise
Solution Approach 1:
The single clasp mechanism is segmented into a dual-locking system with a first clasp and a second clasp. Each clasp independently secures the weight plate, distributing the load and preventing detachment. The first clasp engages with a first slot while the second clasp engages with a second slot, creating redundant security without compromising quick-release functionality.
Solution Approach 2:
The design incorporates preventive measures by positioning the clasps at different locations and orientations on the handle. This spatial distribution ensures that if one clasp experiences stress or potential failure, the other clasp provides backup security, cushioning against the harmful effect of complete detachment before it can occur.
2Reliability
If rotational locking mechanisms with separate safety components are added, then stability is improved, but device complexity increases and maintenance costs rise
Solution Approach 1:
The first clasp and second clasp are integrated into a unified handle structure, sharing common mounting points and structural support. This merging approach provides dual-locking security while avoiding the complexity of completely separate safety mechanisms, reducing the overall number of discrete components and simplifying maintenance.
3Strength
If threaded tightening or pin locking methods are used, then connection strength is improved, but adjustment efficiency deteriorates
Solution Approach 1:
The clasp mechanisms are designed to be self-securing through spring-loaded engagement. When the weight plate is inserted, the springs automatically drive the clasps into the slots, creating a secure connection without requiring manual threading or pin insertion. This self-service mechanism maintains strong connections while enabling rapid weight adjustments.

AI summary
This invention relates to a vertical plug-in weight plate device, which aims to address the issues of inconvenient weight adjustment and low flexibility in the use of existing weight plate devices. The weight plate device includes a handle, a weight plate, and a knob with a limiting rod. Fixed plates are located at both ends of the handle, and these fixed plates and the handle form a longitudinal plug-in channel through a through-hole structure. The center of the weight plate features a through-hole and an installation slot. The limiting rod fits into the through-hole to achieve longitudinal positioning. Meanwhile, the limiting surface of the knob aligns with the installation slot width to complete the lateral locking. The knob contains an elastic snap-fit structure, and a button drives the positioning protrusion to form a secondary lock with the positioning hole of the weight plate, ensuring stability during use. This solution enables tool-free quick disassembly of the weight plate and offers multi-gradient weight adjustment. Additionally, the use of longitudinal plug-in and dual-locking mechanisms significantly improves safety and operational efficiency. It is particularly suitable for high-intensity training scenarios.
