Adjustable Weightlifting Equipment with Safety Lock Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing weightlifting equipment is inconvenient and poses safety hazards due to the need to manually remove and adjust heavy weight stacks, which can lead to accidents during replacement and adjustment.
Innovation Solution
The multifunctional adjustable weightlifting equipment features a safety lock assembly between the grip and weight mounting assembly, allowing for safe and convenient grip replacement, and a weight mounting assembly with cam mechanisms for easy weight adjustment without handling the weight stack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If weight stacks are directly mounted on two sides of the grip, then the structure is simple, but it is inconvenient to replace weight stacks and prone to injury during replacement
Solution Approach 1:
The weight mounting assembly is divided into separate components: the grip, the safety lock assembly, and the weight stack. The safety lock assembly acts as an intermediate segment that connects the grip to the weight stack, allowing the weight stack to be mounted and adjusted without direct handling, thus improving replacement convenience while maintaining structural organization.
Solution Approach 2:
The safety lock assembly serves as an intermediary component between the grip and the weight stack. It provides a secure connection point that allows weight stacks to be mounted and adjusted without requiring direct manual handling of the heavy weight stacks, thereby improving operational safety and convenience.
2Weight of moving object
If weight stacks are heavy, then the weightlifting function is effective, but there is a certain potential safety hazard in the adjusting process due to the heavy weight stack
Solution Approach 1:
The safety lock assembly acts as an intermediary that secures the weight stack to the grip. It includes locking mechanisms (lockpins, hooks, and locking grooves) that ensure the heavy weight stack remains firmly attached during exercise while allowing safe adjustment when needed, thus maintaining both effectiveness and safety.
Solution Approach 2:
The safety lock assembly is pre-configured with locking mechanisms that automatically secure the weight stack before exercise begins. The cam mechanisms are positioned to engage with the weight stack, ensuring that the heavy weight is securely held in place before any lifting action occurs, preventing safety hazards during adjustment and use.
3Adaptability or versatility
If grips are replaced frequently, then exercise variety is improved, but the replacement process is inconvenient and time-consuming
Solution Approach 1:
The grip system is segmented into detachable components that can be quickly exchanged. The safety lock assembly provides a standardized interface that allows different grip types to be rapidly swapped without complex disassembly, improving exercise variety while minimizing time loss during replacement.
Solution Approach 2:
The safety lock assembly serves multiple functions: it secures the weight stack, enables grip replacement, and provides a standardized mounting interface. This multi-functionality allows various grip types to be accommodated through the same mounting mechanism, improving versatility while streamlining the replacement process.
4Reliability
If the safety lock assembly is added, then grip replacement safety is improved, but the device complexity increases
Solution Approach 1:
The safety lock assembly is designed as a separate, modular component that attaches to the grip. This segmentation allows the safety features to be added without redesigning the entire weightlifting equipment, maintaining structural organization while improving replacement safety.
Solution Approach 2:
The safety lock assembly introduces intermediary locking mechanisms (lockpins, hooks, and locking grooves) that provide secure attachment points. These additional components enhance safety during grip replacement and weight adjustment, ensuring that the heavy weight stacks remain securely mounted while allowing controlled access for adjustments.
