Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a buckle or bolt hole is used for fixation, then the pull device can be fixed to external objects, but it cannot be fixed to various gaps such as door jamb gaps
Solution Approach 1:
The clamping member is designed to be movable along the pull band, allowing dynamic adjustment of the clamping position and orientation. This enables the fixation structure to adapt to various gap configurations (door jamb gaps, window frame gaps, etc.) while maintaining a relatively simple overall structure. The movable clamping block can be positioned at different locations to match different gap widths and positions.
Solution Approach 2:
The clamping member's clamping force and position parameters can be adjusted to match different gap widths and positions. By changing the clamping member's position along the pull band and adjusting its clamping force, the same simple structure can effectively fix the pull device to various types of gaps without requiring multiple specialized fixation components.
2Reliability
If a fixed fixation point is used, then the structure is simple, but the fixing point moves during exercise affecting stability
Solution Approach 1:
The clamping member is designed to be movable along the pull band, allowing it to dynamically adjust its position in response to forces applied during exercise. This prevents the fixing point from moving or shifting during use, as the clamping member can reposition itself to maintain optimal clamping contact with the gap surfaces, thereby improving fixation stability without requiring a complex active control system.
Solution Approach 2:
The clamping member automatically adjusts its position and maintains clamping force in response to loads applied during exercise. The elastic element provides continuous pressure that allows the clamping member to self-adjust to positional changes or movement, ensuring stable fixation without requiring external control mechanisms or complex active systems.
3Adaptability or versatility
If multiple clamping blocks are provided to adapt to different gap widths, then the adaptability improves, but the device complexity increases
Solution Approach 1:
Instead of providing multiple separate clamping blocks for different gap widths, the invention uses a single movable clamping member that can be positioned at different locations along the pull band. This dynamic positioning capability allows the same clamping member to adapt to various gap widths by adjusting its position, thereby achieving gap width adaptability without increasing device complexity through multiple components.

AI summary
A pull device fixing apparatus and a pull device using same. The pull device fixing apparatus includes a pull band, where a fixed member is provided at an end of the pull band, and the fixed member enables the pull band to unidirectionally pass through a gap through which the fixed member is incapable of passing; a connecting member for connection to a pull device is provided at the other end of the pull band; a clamping member is provided on the pull band, and the thickness of the clamping member is adaptively adjustable depending on the width of the gap, so as to keep the fixed member fixed. The pull device fixing apparatus is suitable for stably fixing the pull device to various gaps, such as a door jamb gap, and is self-adapted to widths of various gaps through the clamping member, so that the fixed member is stably fixed at a point of the gap and refrains from a movement during exercise carried out by a user which affects the use of the pull device.
