Clamping Base with Prestressed Protective Cap for Tool Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging containers with clamping bases require significant force to insert objects, risking hand injuries and lack the ability to increase clamping force once the object is held, limiting their functionality.
Innovation Solution
A packaging container with a clamping base featuring elastic clamping jaws that are prestressed by a protective cap, allowing for easy object insertion and high holding force when the cap is attached, utilizing edge and wall areas of the cap to deform the jaws radially inwardly, reducing the clamping reception diameter and enhancing clamping force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the clamping reception is formed by flexible ribs that are fixed at the base, then the clamping force is sufficient to hold the object, but the insertion force required is too high causing hand injuries
Solution Approach 1:
The clamping jaw is made dynamically adjustable through the attachment of the protective cap. When the cap is attached, it prestresses the clamping jaw to increase clamping force. When removed, the clamping force decreases to allow easy insertion. This dynamic adjustment resolves the contradiction between high clamping force and easy insertion.
Solution Approach 2:
The clamping force parameter is changed by attaching or removing the protective cap. The cap modifies the physical state of the clamping jaw through prestressing, allowing the system to switch between high clamping force mode (cap attached) and low insertion force mode (cap removed).
2Reliability
If the clamping force is increased to hold heavy tools securely, then the holding capability improves, but the insertion becomes difficult and dangerous
Solution Approach 1:
The protective cap is attached beforehand to prestress the clamping jaw, preparing the system for secure holding. This preliminary action ensures that when the tool is inserted, the clamping jaw is already in the optimal state for both easy insertion (due to prestressing) and secure holding (due to increased clamping force).
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
Enables easy insertion of objects with reduced manual force, preventing hand injuries and providing a high clamping force sufficient to secure heavy tools and instruments, ensuring protection against damage even if the packaging falls.
Implementation Method 1
The attachment of the cap to the clamping base prestresses the clamping jaw in a direction of the clamping reception... the necessary and desired high clamping force is achieved... particular edges or areas of the wall of the cap abut against the outside circumference of the clamping jaws in order to move said clamping jaws radially inwardly in direction of the clamping reception

AI summary
A packaging container with a clamping base and an attachable protective cap serves for a unilateral, clamping or holding of a tool, an instrument, or another longitudinal object, where the clamping base comprises a clamping holder with a plurality of springy clamping jaws fastened on one side which define a nearly centric, central clamping reception, in which clamping reception the tool is inserted and held clampingly.In order to achieve that the insertion force to be applied is low when the packaging container is equipped, however, a high clamping force is given with the protective cap attached. The protective cap abuts against the outside circumference of the clamping jaws when it is attached to the clamping base and prestresses said clamping jaws in direction of the clamping reception.
