Clamp Sensor Sliding Mechanism for Wire Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional clamp sensors require complex operations to clamp wires, as the sensor structures must move relative to the wire, making them difficult to use effectively.
Innovation Solution
A clamp sensor design featuring a main body with fixed and rotatable clamp units, an opening/closing mechanism with a biasing member and sliding portion, allowing for the clamp units to close without moving relative to the main body, ensuring reliable detection and improved operability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sensor structures move relative to the wire during closing operation, then the wire may be clamped effectively, but the receiver becomes difficult to operate and requires complex sliding operations
Solution Approach 1:
Instead of moving the sensor structures relative to the wire during closing, the invention inverts the approach by keeping the sensor structures stationary relative to the main body and allowing the wire to be inserted when the front ends are open. The closing operation then simply brings the front ends together without any relative movement between the sensor structures and the main body, eliminating the complex sliding operation requirement.
2Reliability
If the front ends of sensor structures are closed by sliding operation, then the wire can be clamped, but the entire receiver must be moved during operation making it difficult to use
Solution Approach 1:
The invention segments the closing function into two independent parts: the sensor structures remain fixed to the main body, while only the front ends are made movable relative to each other. This segmentation allows the front ends to close together without requiring the entire receiver to be moved, simplifying the operation to a simple pressing action rather than complex sliding operations.
3Device complexity
If the sensor structures are fixed to the main body, then the structure is simplified, but the front ends cannot open and close to clamp the wire
Solution Approach 1:
The invention applies local quality by making only the front ends of the sensor structures movable while keeping the main bodies fixed. This localized mobility allows the front ends to open and close for clamping wires, while the rest of the structure remains simple and fixed, achieving both structural simplicity and functional adaptability.
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
Enhances operability by allowing the clamp units to close without adjusting the sensor's position relative to the wire, preventing incomplete closure and improving detection accuracy.
Implementation Method 1
when a wire on which a current is flowing has been clamped by the clamp sensor (i.e., the sensor structures), it is possible, using the clamp sensor, to detect a magnetic field produced by the wire due to the current flowing through the wire

AI summary
A clamp sensor detects a detected value for a clamped object and includes: a main body with two main surfaces and two side surfaces; first and second clamp units whose front ends can open and close and form a ring-shaped body surrounding the clamped object; and an opening/closing mechanism for the clamp units. The first clamp unit is fixed to the main body at one side surface. The second clamp unit has a base end rotatably supported by a support shaft disposed toward the other side surface. The opening/closing mechanism includes: a biasing member biasing the second clamp unit to open the clamp units; and a sliding portion disposed on the other side surface and capable of sliding along the length of the main body. When slid toward the clamp units, the sliding portion presses the second clamp unit to close the front ends.
