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

VSEngineering 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

Engineering Contradiction:
Improveweight adjustment flexibilityVSAvoidexercise interruption time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

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.

Inventive Principle:
Principle #1Segmentation

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

Engineering Contradiction:
Improvetraining intensity variationVSAvoidweight block coupling mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Weight of moving object

If multiple weight blocks are combined, then available weight range is increased, but the weight adjustment process becomes more complex

Engineering Contradiction:
Improvetotal weight rangeVSAvoidweight block coupling operation
Core Design Contradiction:
Weight of moving objectVSEase of operation

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.

Inventive Principle:
Principle #25Self-service

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).
