Dual Weight-Block Training Mechanism for Seamless Load Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional weight training devices require manual adjustment of weight settings during high-intensity training, which is time-consuming and interrupts the exercise flow.
Innovation Solution
A training device with a first and second actuating element for lifting independent weight blocks, allowing the user to combine or decouple weight blocks during a workout, enabling flexible weight adjustments without interrupting the exercise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual weight adjustment is used on conventional training devices, then weight settings can be changed, but the exercise flow is interrupted and time is lost
Solution Approach 1:
The weight system is segmented into multiple independent weight blocks (first weight block, second weight block) that can be selectively coupled and decoupled. Each weight block can be independently adjusted and combined, allowing users to modify weight configuration without interrupting the exercise flow. The segmentation enables rapid weight changes by simply engaging or disengaging coupling mechanisms between blocks.
2Adaptability or versatility
If fixed weight settings are used on training devices, then device complexity is reduced, but adaptability for different training intensities is limited
Solution Approach 1:
The weight blocks are designed with nested coupling capabilities where the second weight block can be positioned and coupled relative to the first weight block. The coupling mechanisms (such as locking pins, clamps, or magnetic couplings) are integrated into the weight block structures themselves, allowing for compact nesting when coupled and independent separation when decoupled. This nesting approach minimizes spatial requirements while maintaining adaptability.
3Weight of moving object
If multiple weight blocks are combined, then available weight range is increased, but the weight adjustment process becomes more complex
Solution Approach 1:
The weight blocks incorporate self-aligning and self-locking coupling mechanisms that automatically guide the coupling process. Features such as guide rails, tapered interfaces, or magnetic attraction zones ensure that weight blocks naturally align during coupling, reducing the precision required by the user. The locking mechanisms may be spring-loaded or gravity-assisted, allowing automatic engagement once the blocks are positioned, thereby simplifying the operation.

AI summary
A training device (1) for muscle building comprises a first actuating element (5) for lifting a first weight block (7) and a second actuating element (8) for lifting a second weight block (9), wherein the second weight block (9) can be moved independently relative to the first weight block (7) between a lowered starting position and a raised position, wherein the first weight block (7) can be coupled to the second weight block (9) and the first actuating element (5) allows the first weight block (7) and the second weight block (9) to be moved together. This allows the weight load to be varied during training, whereby the first actuating element (5) can be used to lift either only the first weight block (7) or both the weight block (7) and the second weight block (9).
