Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pneumatic crimping tools lack a straightforward method for adjusting the crimping depth, making it difficult to achieve precise and consistent crimping.
Innovation Solution
A pneumatic crimping tool with an adjustable crimping depth facilitated by a rotating adjusting wheel that surrounds the crimping axis, featuring an external thread for precise positioning and a stop to limit the radial path of punches, along with a concentric design for ease of use and visual appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If pneumatic crimping tools are designed without complex adjustment mechanisms, then device complexity is reduced, but crimping depth adjustment becomes difficult or impossible
Solution Approach 1:
The adjusting wheel is nested concentrically around the crimping axis, with the stop mechanism integrated into the wheel structure. This nesting allows the adjustment function to be incorporated into the existing cylindrical housing without adding external complexity, while still providing precise crimping depth control through the rotating wheel and stop mechanism.
Solution Approach 2:
The adjusting wheel provides dynamic adjustment capability by allowing the operator to rotate the wheel to different positions, each corresponding to a specific crimping depth. The stop mechanism dynamically limits the radial path of punches based on the wheel's rotational position, enabling flexible and precise control without complex mechanical systems.
2Ease of manufacture
If a concentric adjusting wheel design is used, then visual appeal and simplicity are improved, but the mechanism for limiting punch radial path must be precisely integrated
Solution Approach 1:
The stop is integrated as part of the adjusting wheel structure itself, nested within the concentric design. This integration ensures that the visual simplicity of the concentric arrangement is maintained while the stop mechanism precisely limits the punch radial path through its geometric relationship with the crimping cone and punches.
Solution Approach 2:
The stop mechanism on the adjusting wheel automatically limits the punch radial path based on the wheel's rotational position without requiring additional control systems. The geometric configuration of the stop, crimping cone, and punches creates a self-regulating system where the adjusting wheel's position directly determines the crimping depth.
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 and precise adjustment of crimping depth, improving the consistency and quality of crimping operations, while maintaining a device-technically simple and visually appealing design.
Implementation Method 1
The adjusting wheel is positionable along the crimping axis via an external thread and has a stop for limiting the crimping depth, which indirectly limits the radial path of the punches. The external thread engages in an internal thread of the at least sectionally cylindrical housing or of an outer ring fixed to the housing.
Implementation Method 2
A pneumatic crimping tool refers to a semi-automatic crimping device whose energy supply for forming the socket-like portion of the contact is provided solely via at least one terminal for a pressurized fluid, usually inexpensive compressed air.

AI summary
A pneumatic crimping tool has a crimping axis, along which a contact and a cable end can be introduced into a crimping opening, wherein a plurality of punches can be introduced into the crimping opening radially to the crimping axis. An adjusting wheel is provided, which surrounds the crimping axis, the radial crimping depth being adjustable by rotating the adjusting wheel.
