Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If adjustable gripping devices are designed to be versatile and adaptable, then the device complexity and manufacturing cost increase
Solution Approach 1:
The device is divided into modular components: a telescoping body with segmented sections that can extend and retract, a separate trigger mechanism, and interchangeable gripping elements. This segmentation allows the device to maintain adjustability while reducing overall complexity through standardized connection points and modular assembly.
Solution Approach 2:
The gripping device incorporates multiple gripping elements that can be interchanged to handle different object types and sizes. The telescoping body and trigger mechanism serve universal functions across various gripping scenarios, allowing one device to perform multiple gripping tasks without requiring separate specialized tools for each function.
2Adaptability or versatility
If adjustable gripping devices are designed to be versatile and adaptable, then the manufacturing cost increases
Solution Approach 1:
By segmenting the device into modular components with standardized interfaces, manufacturing becomes more efficient through specialized production of individual modules that can be mass-produced and then assembled. This reduces tooling costs and allows for more economical manufacturing processes compared to producing complex adjustable devices as monolithic units.
Solution Approach 2:
The gripping elements are designed as replaceable, relatively simple components that can be manufactured at low cost. When worn or damaged, these elements can be replaced rather than replacing the entire device, reducing the overall cost burden on the user and allowing the manufacturer to use more economical materials and production methods for these consumable parts.
3Ease of manufacture
If gripping devices are made non-adjustable, then the manufacturing cost decreases and simplicity increases, but the ability to grasp objects in various positions is limited
Solution Approach 1:
The device incorporates a telescoping body that can dynamically change its length to reach objects at different distances, and a trigger mechanism that dynamically adjusts the gripping force and element positioning. This dynamic capability allows a single device structure to adapt to various grasping situations without requiring multiple fixed-length devices, maintaining manufacturing simplicity while enhancing versatility.

AI summary
A gripping assembly having a first or holding end with a pair of rotatable operating elements held therein and connected to a wind assembly having a flexible, non-resilient link held by one end therein for operating a pair of gripping elements. The gripping assembly is movably mounted on a distal end of an adjustable, two part hollow body. The wind assembly is captured between a pair of lever housings and includes a constant force spring to allow the flexible, non-resilient link to be wound onto or from the wind assembly.
