Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional U-shaped lock is used, then the structure is simple, but the lock cannot adjust size according to the object and has fixed folding direction
Solution Approach 1:
The lock body is divided into multiple segments including a first body segment and a second body segment that can relatively move against each other. The cord is segmented into a first cord segment and a second cord segment that can be independently positioned. This segmentation enables the lock to adjust its effective length and folding direction by controlling the relative positions of these segments, thereby achieving size adaptability while maintaining a relatively simple overall structure.
Solution Approach 2:
The lock incorporates movable components including a movable end of the first body segment, a movable end of the second body segment, and a movable end of the cord. These dynamic elements allow the lock to change its configuration by moving the segments relative to each other, enabling adjustment of the locking size and folding direction without requiring a completely different lock structure for each application.
2Ease of operation
If the joint bar hoop is made foldable, then the use flexibility is improved, but the size adjustment according to object size is still limited
Solution Approach 1:
The lock body is divided into multiple segments including a first body segment and a second body segment that can relatively move against each other. The cord is segmented into a first cord segment and a second cord segment that can be independently positioned. This segmentation enables the lock to adjust its effective length and folding direction by controlling the relative positions of these segments, thereby achieving size adaptability while maintaining a relatively simple overall structure.
Solution Approach 2:
The lock mechanism operates in multiple dimensions by allowing the first body segment and second body segment to move relative to each other in different directions. The cord segments can be positioned at different locations and orientations. This multi-dimensional movement capability enables the lock to adapt to various object sizes and shapes by changing the spatial arrangement of its components, greatly expanding the size adjustment range while maintaining ease of operation.
3Reliability
If interference members are added to restrict cord movement, then the locking reliability is improved, but the device complexity increases
Solution Approach 1:
The first interference member and second interference member are integrated into the existing lock body structure rather than being separate add-on components. The first interference member is positioned within the first body segment and the second interference member within the second body segment, merging the restriction function with the structural components. This integration approach improves locking reliability by providing multiple restriction points while minimizing the increase in overall device complexity.
Solution Approach 2:
The interference members act as intermediary elements between the cord segments and the lock body. These intermediaries provide the restriction function by physically blocking the cord from moving in unwanted directions, thereby improving locking reliability. The interference members serve as mediators that translate the structural configuration into functional restriction without requiring complex control mechanisms, thus improving reliability with minimal complexity increase.
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 size adjustment and secure locking of objects, reducing the risk of damage to the device during use.
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.
