Nested Reversible Interlocking Assemblies for Adjustable Span Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamping devices are limited by their maximum usable length, which is often less than their overall length, and typically allow only a single clamping configuration, leading to inefficiencies in storage, maneuverability, and capital costs due to the need for multiple clamps of varying sizes.
Innovation Solution
A clamping device with nested reversible interlocking assemblies, comprising an inner and outer bar assembly, a locking mechanism, and a movable jaw, allowing for adjustable span and multiple configurations, enabling the device to exceed its minimum overall length and accommodate various workpiece sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single clamping configuration with directly opposing jaws is used, then the device structure is simple, but the adaptability to different workpiece sizes and orientations is limited
Solution Approach 1:
The clamp is divided into two independent assemblies (first assembly with inner bar and fixed jaw, second assembly with outer bar and movable jaw) that can be configured in multiple orientations. This segmentation allows the same basic structure to serve multiple clamping configurations without increasing overall device complexity.
Solution Approach 2:
The clamp design enables a single device to perform multiple clamping functions by allowing the assemblies to be oriented in different configurations (parallel jaws, opposing jaws, angled clamps), making one device replace multiple specialized clamps.
2Length of moving object
If the overall length of the clamp is increased to accommodate larger workpieces, then the maximum usable length increases, but the storage space requirement and maneuverability deteriorate
Solution Approach 1:
The first assembly with the inner bar is nested within the second assembly with the outer bar, allowing the clamp to be compacted to a small storage size while maintaining the capability to extend to a large span between jaws when needed. The nested configuration reduces storage volume without sacrificing maximum usable length.
3Adaptability or versatility
If multiple clamps of assorted sizes are purchased to handle various workpiece sizes, then the adaptability improves, but the capital costs and storage space requirements increase
Solution Approach 1:
A single clamp device is designed to replace multiple specialized clamps by enabling various clamping configurations and span lengths through the nested reversible assembly design, thereby reducing the total number of clamps needed in the workshop.
Solution Approach 2:
The functionality of multiple clamps with different jaw configurations and lengths is merged into one device through the reversible nested assembly mechanism, allowing one clamp to perform the work of several.
4Speed
If the clamp length is reduced for better maneuverability, then the maximum usable length decreases, but the ability to handle larger workpieces is lost
Solution Approach 1:
The nested assembly allows the clamp to be stored and transported in a compact form for improved maneuverability, while the same nested structure enables the bars to be extended to their full length when clamping larger workpieces, maintaining both maneuverability and maximum usable length.

AI summary
The present invention relates to a work holding and clamping device, which increases the usable span to almost twice its stored length. This clamping device has an inner and outer assembly which are nested, and each assembly is made of a rectangular tube with a jaw affixed to one end. The inner assembly contains a locking mechanism to allow for length adjustment. When arranged so that the jaws are on the same side of the respective assemblies, the clamp is capable of a span that is almost equal to the length of the inner assembly. When arranged so that the jaws are on opposite sides of the respective assemblies, the clamp is capable of a span that is almost equal to the sum of the length of the inner assembly and outer assembly.
