Cable Fastener Rotational Engagement for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable fasteners require a large force to attach and have high rigidity, which complicates workability and makes them difficult to store due to their height, especially when trying to increase the holding force against a plate-like support portion.
Innovation Solution
The cable fastener design includes a base portion with flexible and hard plate-like cable holding portions and engaging portions, allowing for easy attachment with reduced force requirements by sandwiching the edge of the attachment hole between the fixing and base portions, and featuring a compact, flat shape for efficient storage and manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the cable fastener uses high rigidity to increase holding force against the plate-like support portion, then the holding force is improved, but the attachment force required increases and workability deteriorates
Solution Approach 1:
The cable fastener applies local quality by creating a localized high-stress concentration point at the reference point on the base portion. This allows the fastener to achieve high holding force through rotational engagement at a specific location while maintaining overall flexibility and ease of attachment. The stress concentration point enables effective engagement with the plate-like support portion without requiring high attachment force across the entire structure.
2Strength
If the cable fastener increases height to improve holding force, then the holding force is improved, but the storage space required increases
Solution Approach 1:
The cable fastener transitions from a height-based holding mechanism to a rotational engagement mechanism. By introducing a reference point for rotation on the base portion, the fastener achieves high holding force through angular engagement rather than vertical height. This dimensional shift allows the fastener to maintain compact size for storage while providing sufficient holding force through the rotational engagement with the plate-like support portion.
3Ease of manufacture
If the cable fastener uses elastic deformation of the base portion for attachment, then the attachment process is simplified, but the attachment force required increases
Solution Approach 1:
The cable fastener modifies the engagement parameter by introducing a reference point that enables rotational movement. Instead of relying solely on elastic deformation requiring high force, the fastener uses controlled rotation around the reference point to achieve engagement. This parameter change allows the base portion to deform elastically in a controlled manner during rotation, simplifying the attachment process while reducing the peak attachment force required compared to pure elastic deformation methods.
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
This design reduces the load needed for attachment, maintains a high holding force, and allows for a shorter, more compact form that can be easily stored, improving workability and space efficiency.
Implementation Method 1
the two cable holding portions are configured to be bendingly deformed toward the first surface of the base portion
Implementation Method 2
the base portion or the fixing portion is elastically deformed, and the fixing portion fixes the base portion to the plate-like support portion in a state where an edge portion of the attachment hole of the plate-like support portion is sandwiched between the fixing portion and the base portion

AI summary
In a cable fastener (1), a fixing portion (10) is a projection projecting from a second surface of a base portion (11) that is opposite to a first surface for supporting a cable (8), and when the fixing portion (10) is inserted into a hole of a plate-like support portion (800) and then the base portion (11) is rotated, fixes the base portion (11) to the plate-like support portion (800). Two cable holding portions (12) extend from the base portion (11) toward opposite sides of the base portion (11), and are configured to be bendingly deformed toward the first surface of the base portion (11). Two engaging portions (13) are configured to be engaged with each other such that the base portion (11) and the two cable holding portions (12) are kept to be in an annular state.
