Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carabiners used in outdoor sports lack the ability to consistently maintain the required length of a harness, leading to instability and increased risk of accidents in activities like rock climbing and skiing.
Innovation Solution
A carabiner with a pulling rope adjustment mechanism that includes a clockwork spring, fixed gear, and locking mechanism, allowing users to manually adjust the length of the harness body and ensure it remains securely locked.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a movable harness body is used to increase application flexibility, then the adaptability is improved, but the stability deteriorates
Solution Approach 1:
The harness body is designed to be dynamically adjustable in length through the pulling rope adjustment mechanism. Users can change the harness length from fixed to adjustable states, allowing adaptation to different application scenarios while maintaining stability when locked at desired lengths.
Solution Approach 2:
The length parameter of the harness body can be changed by users through the adjustment mechanism. The harness can be extended or retracted to different lengths and locked in position, enabling parameter adjustment to meet different application needs while ensuring stability during use.
2Stability of the object's composition
If a locking mechanism is added to fix harness length, then the stability is improved, but the device complexity increases
Solution Approach 1:
The locking function is merged with the adjustment mechanism itself. The pulling rope adjustment mechanism integrates both length adjustment and locking functions in one system, avoiding the need for separate locking devices and reducing overall structural complexity.
Solution Approach 2:
The adjustment mechanism is designed to be self-locking through the meshing of fixed gear and moving gear. When the moving gear engages with the fixed gear, it automatically locks the harness at the adjusted length without requiring additional locking operations or complex locking mechanisms.
3Ease of operation
If a manual adjustment mechanism is implemented, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The complex mechanical adjustment system is replaced with a simplified gear-based mechanism. The fixed gear and moving gear provide intuitive manual adjustment through simple rotational motion, replacing what would otherwise require complex cable systems or multiple linkage components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The carabiner enables quick and easy adjustment of the harness length, reducing operational complexity and enhancing safety by preventing accidental loosening during high-risk activities.
Implementation Method 1
A pulling rope adjustment mechanism is fixedly arranged at an outer end of the main body. The pulling rope adjustment mechanism includes an upper cover, a lower cover, a clockwork spring
Implementation Method 2
A fixed gear is arranged at an inner end of the pulling rope adjustment mechanism. A moving gear is arranged at an outer end of the clamping pillar in a sleeving manner. The moving gear meshes with the fixed gear
Implementation Method 3
A locking mechanism is arranged in the threaded hole through threads

AI summary
The present disclosure relates to field of outdoor sports, and discloses a carabiner capable of adjusting a length of a harness, including a main body. A limit pillar is fixedly arranged at one side of the main body. In the present disclosure, to mount the carabiner capable of adjusting the length of the harness, a clockwork spring is first placed in a groove of the main body, and a hole of a fixed gear is aligned with the limit pillar; then, a moving gear is placed in a clamping pillar of an upper cover; and finally, a lower cover is aligned with the clamping pillar to complete mounting. Through the meshing between the fixed gear and the moving gear, the harness body can be fixed at a specific length, thereby ensuring the safety in high-risk activities such as rock climbing and hiking.
