Telescoping Clamp Jaws for Variable Power Line Blanket Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Linemen face challenges in efficiently clamping electrically insulating blankets on power lines due to the need for multiple clamp sizes to accommodate varying line sizes and blanket thicknesses, which limits space in their bucket tools.
Innovation Solution
An adjustable clamp design featuring pivotally joined handles with jaws that can move between retracted and extended positions, allowing for adjustment to fit different power line sizes and blanket thicknesses, and incorporating a spring for clamping force and a detent mechanism for locking positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple clamp sizes are carried to accommodate different power line sizes and blanket thicknesses, then adaptability is improved, but device complexity and space requirements increase
Solution Approach 1:
The clamp incorporates movable jaws with telescoping inner and outer portions that can extend and retract to adjust the jaw length. This dynamic structure allows a single clamp to adapt to different power line sizes and blanket thicknesses by changing the jaw length configuration, eliminating the need to carry multiple fixed-size clamps.
Solution Approach 2:
The adjustable clamp is designed to perform multiple functions by accommodating various power line diameters and blanket thicknesses through its adjustable jaw mechanism. A single universal clamp design replaces the need for multiple specialized clamps, reducing the number of tools linemen must carry while maintaining versatility across different application scenarios.
2Adaptability or versatility
If multiple clamp sizes are carried to accommodate different power line sizes and blanket thicknesses, then adaptability is improved, but space requirements increase
Solution Approach 1:
The movable jaw mechanism allows the clamp to change its effective size dynamically. The inner jaw portion can telescope within the outer jaw portion, enabling the same physical clamp to present different jaw lengths as needed. This reduces the volume of tools required in the bucket while maintaining adaptability to different line sizes.
Solution Approach 2:
The inner jaw portion is housed within the outer jaw portion in a telescoping arrangement, similar to nested dolls. This nesting configuration allows the clamp to compact its overall size when not in use while still providing extended jaw length when needed, significantly reducing the space required in the lineman's bucket.
3Device complexity
If jaw length is fixed, then device complexity is reduced, but adaptability worsens
Solution Approach 1:
Rather than using multiple fixed-size clamps, the invention employs a single clamp with dynamically adjustable jaw length. The telescoping mechanism allows the jaw to extend or retract based on the specific application requirements, providing adaptability without requiring a collection of different fixed-size clamps.
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 adjustable clamp reduces the number of clamps needed by accommodating various sizes and thicknesses, thereby optimizing space in bucket tools and enhancing operational efficiency for linemen.
Implementation Method 1
a spring associated with the first and second handles that exerts a biasing force to move the first and second handles in a direction away from each other and cause the first and second nose tips to apply a clamping force
Implementation Method 2
Each jaw includes a lock comprising a detent mechanism that selectively locks the jaw in the extended and retracted positions

AI summary
An adjustable clamp has first and second handles that are pivotally joined together and first and second jaws that extend respectively from the first and second handles and end in first and second nose tips. Each of the first and second jaws has an inner portion that is housed within an outer portion in a manner to allow relative movement between the inner portion and the outer portion to move the first and second jaws between a retracted position and an extended position to decrease and increase a longitudinal length of the first and second jaws. A spring is associated with the first and second handles and exerts a biasing force to move the first and second handles away from each other and cause the first and second nose tips to apply a clamping force.
