Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional U-shaped lock with a fixed rod structure is used, then the structure is simple and easy to manufacture, but the lock cannot deform and has poor adaptability to different object sizes
Solution Approach 1:
The patent applies the dynamics principle by replacing the fixed rigid rod structure with a flexible cord that can deform and adapt to different object sizes. The cord can be bent and shaped around various objects, providing adaptability while maintaining structural simplicity. The interference members provide controlled restrictions on the cord's movement, enabling the system to maintain both flexibility and functional control.
2Ease of operation
If a joint bar hoop with fixed folding direction is used, then the structure is simple, but the folding direction is fixed and use convenience is reduced
Solution Approach 1:
The patent implements dynamics by allowing the cord to move freely in multiple directions within the body without fixed folding constraints. The interference members selectively restrict the cord's movement based on operational needs, enabling convenient adjustment and positioning while maintaining overall structural simplicity.
Solution Approach 2:
The patent divides the locking mechanism into separate functional components: the cord for flexible positioning, the interference members for directional restriction, and the locking module for securing. This segmentation allows each component to perform its specific function independently, improving ease of operation while keeping the overall structure manageable.
3Adaptability or versatility
If the cord is allowed to move freely in the through portion, then adjustability is improved, but the risk of accidental detachment increases
Solution Approach 1:
The interference members act as intermediaries between the cord and the body, providing selective restriction on the cord's movement. They allow the cord to move freely for positioning purposes while simultaneously preventing accidental detachment by blocking the cord when it reaches certain positions. This intermediary mechanism resolves the contradiction between adjustability and reliability.
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
Enables flexible adjustment to fit various sizes and reduces the risk of damage by allowing controlled detachment and retraction of the cord, enhancing user convenience and durability.
Implementation Method 1
a first elastic member that provides elastic force to the first interference member, so that the first interference member rotates, until one end extends into the through portion to be clamped to the cord located in the through portion
Implementation Method 2
a second elastic member that provides elastic force to the second interference member, so that the second interference member can move to an opening of the groove body

AI summary
The present utility model provides a fixing device, including a body, a cord, a drive device, and a locking module. The body includes a connection portion, a through portion, and a locating portion. The cord includes a connection end and a locating end, the connection end is fixed to the connection portion, and the locating end can pass through the through portion and is detachably connected to the locating portion. The drive device is disposed in the body, is partially exposed from the body, and movably releases a restriction on a movement direction of the cord and a restriction on the locating end detaching from the locating portion. The locking module is disposed in the body and is partially exposed from the body to restrict movement of the drive device.
