Holding Pole Ring Fastener for Single-Person Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing fixing devices for holding poles require two persons to mount, leading to excessive manpower and increased mounting costs.
Innovation Solution
A fixing device comprising a first fastener, a second fastener, and a securing member, where the two ends of the first fastener are radially engaged with the second fastener to form a ring, and the securing member rotatably runs through one of the fasteners to press against the pole, allowing for single-person mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the existing fixing device with two fasteners and screws is used, then the pole can be clamped securely, but two persons are required for mounting which increases manpower and mounting cost
Solution Approach 1:
The patent merges the two separate fasteners into a single integrated fastener body with a U-shaped structure. The first and second fasteners are combined into one piece that forms a complete ring when closed, eliminating the need for separate components and reducing the number of parts from two fasteners plus screws to a single integrated fastener with movable arms.
Solution Approach 2:
The patent implements a self-locking mechanism where the movable arm automatically engages with the pole and locks into position through its own weight and geometric configuration. The spring-loaded design allows the fastener to self-adjust and secure itself without requiring manual intervention from multiple operators, enabling single-person installation.
2Manufacturing precision
If two operators are required to level and align the fasteners, then proper alignment can be achieved, but excessive manpower is occupied
Solution Approach 1:
The patent employs asymmetric design in the movable arm mechanism where one arm is fixed and the other is movable, allowing sequential engagement. This asymmetric configuration enables the first operator to position the fixed arm while the movable arm automatically aligns and engages with the pole, eliminating the need for a second operator to perform alignment tasks.
Solution Approach 2:
The patent incorporates pre-aligned geometric features in the fastener body that automatically guide the movable arm into the correct position during installation. The predetermined angles and contact surfaces ensure proper alignment is achieved automatically as the device is installed, eliminating the need for manual leveling and alignment operations.
3Strength
If multiple screws and threaded holes are used, then the fastening strength is sufficient, but the device requires more components and assembly steps
Solution Approach 1:
The patent extracts and eliminates the screws and threaded holes from the design by replacing them with a friction-based clamping mechanism. The movable arm applies continuous radial pressure against the pole through spring force and geometric constraint, providing sufficient clamping strength without requiring threaded fasteners, thereby reducing the component count from multiple screws and holes to a screwless design.
Solution Approach 2:
The patent substitutes the traditional mechanical screw-threaded hole fastening system with a spring-loaded friction clamping system. Instead of using threads to convert rotational motion into clamping force, the design uses elastic deformation of springs and geometric constraints to generate and maintain clamping pressure, eliminating the need for threaded connections while maintaining adequate fastening strength.
