Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the damping element is assembled between the fastening band and the sliding arm to form a pivot structure, then the pivot structure is initially stable, but after multiple pivot operations the damping element deforms and is exposed outside due to friction, affecting appearance and function
Solution Approach 1:
The patent applies beforehand cushioning by designing a buffering space between the damping element and the bottom wall of the accommodating groove. This space prevents the damping element from directly contacting the bottom wall during rotation, reducing friction and wear before damage occurs. The inclined surfaces also provide gradual transition and reduced impact forces on the damping element during pivot operations.
Solution Approach 2:
The patent uses an intermediary approach by introducing the buffering space as a mediator between the damping element and the accommodating groove bottom wall. This space acts as a cushion that absorbs friction forces and prevents direct contact, thereby protecting the damping element from deformation and exposure during repeated use.
2Force
If the damping element is constrained tightly in the pivot structure, then initial friction resistance is reduced, but the damping element deforms under repeated stress and exposure occurs
Solution Approach 1:
The buffering space provides beforehand cushioning by preventing direct contact between the damping element and the groove bottom wall. This cushioning effect reduces the friction resistance and stress concentration on the damping element, maintaining its structural integrity during repeated pivot operations without causing deformation or exposure.
3Ease of operation
If the pivot structure allows free rotation, then operational flexibility is improved, but the damping element experiences increased friction and deformation over time
Solution Approach 1:
The buffering space and inclined surfaces work together to provide beforehand cushioning during rotation operations. This design allows free rotation and operational flexibility while simultaneously reducing friction and stress on the damping element, preventing deformation and maintaining reliability over extended use.
Solution Approach 2:
The patent applies dimensionality change by creating a buffering space in the vertical dimension (depth of the groove) to protect the damping element during horizontal rotation operations. This additional dimensional consideration allows free rotation while protecting against friction-induced deformation.
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 design ensures a stable pivot structure and normal appearance over long-term use by minimizing deformation and resistance, allowing for flexible and continuous rotation without compromising functionality.
Implementation Method 1
a periphery of a bottom surface of the damping element is inclined outward from bottom to top to form a second inclined surface corresponding to and matched with the first inclined surface. The first inclined surface contacts with the second inclined surface. The second inclined surface abuts against the first inclined surface.
Implementation Method 2
The middle of the bottom surface of the damping element is spaced from a top surface of the bottom wall of the accommodating groove to form a buffering space between the middle of the bottom surface of the damping element and the top surface of the bottom wall of the accommodating groove. When the fastening band is rotated with respect to the sliding arm, the buffering space makes the middle of the bottom surface of the damping element be without contacting the top surface of the bottom wall of the accommodating groove to reduce a resistance force among the damping element, the sliding arm and the fastening band.

AI summary
A hand fixation band includes a fastening band, a sliding arm and a damping element. The fastening band has a main portion, and a connecting portion protruded outward from one end of the main portion. A bottom surface of the connecting portion is defined as a contact surface. The sliding arm is connected with the fastening band. One end of the sliding arm disposed under the connecting portion is recessed downward to form an accommodating groove. A top of a peripheral wall of the accommodating groove is inclined outward from bottom to top to form a first inclined surface. The damping element is disposed in the accommodating groove and contacts with the contact surface. A periphery of a bottom surface of the damping element is inclined outward from bottom to top to form a second inclined surface. The first inclined surface contacts with the second inclined surface.
