Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gripping devices face challenges in assembling a magnetic field generator inside the device housing in a way that is easy, safe, and minimizes installation space and weight, while allowing for stroke-dependent triggering of a switching signal using an external magnetic field sensor.
Innovation Solution
Incorporating a measuring device groove in the guide body to support a magnetic field sensor and a support element on the carriage that holds a magnetic field generator, allowing for internal measurement of carriage movement using an external magnetic field sensor, with minimal impact from gear train play or flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a magnetic field generator is mounted inside the device housing, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The magnetic field generator is integrated into the gripping device housing, combining the measurement function with the existing structural components. This merging approach improves measurement precision by placing the sensor internally while avoiding the need for separate external mounting systems that would increase device complexity.
Solution Approach 2:
The magnetic field generator serves multiple functions: it acts as both a positional reference for the magnetic field sensor and an integral part of the gripping device structure. This multi-functionality allows precise measurement without adding dedicated separate components, thereby reducing overall device complexity.
2Volume of moving object
If a magnetic field generator is mounted inside the device housing, then the installation space is reduced, but the ease of manufacture decreases
Solution Approach 1:
The magnetic field generator is designed as a separate, modular component that can be independently manufactured and then integrated into the housing. This segmentation allows for simplified manufacturing of individual parts while achieving compact internal mounting, reducing installation space without significantly complicating the overall manufacturing process.
Solution Approach 2:
A mounting structure or intermediary component is used to facilitate the integration of the magnetic field generator into the housing. This intermediary element simplifies the assembly process by providing a standardized interface, making the internal mounting easier to manufacture despite the reduced installation space requirements.
3Weight of stationary object
If a magnetic field generator is mounted inside the device housing, then the weight is reduced, but the reliability decreases
Solution Approach 1:
The magnetic field generator is nested within the existing housing structure, utilizing available internal space rather than adding external components. This nesting approach reduces overall weight while maintaining reliability by protecting the magnetic field generator within the established housing environment, which provides mechanical protection and stable mounting conditions.
Solution Approach 2:
The housing structure is designed to provide protective cushioning for the magnetic field generator before any potential damage can occur. This beforehand protection ensures that the internally mounted generator maintains high reliability despite the weight reduction achieved through internal placement, as the housing serves as a pre-established protective barrier.

AI summary
The invention relates to a gripping device with at least two gripping elements (1, 2) arranged to move towards or away from each other, which are mounted on slides (31, 32) in the housing (10) of the gripping device or are articulated by slides via a gear mechanism. A support device (17) is arranged on the housing of the gripping device, in or on which a magnetic field sensor (165) is held fixedly or adjustably. A support element is arranged on at least one slide (31, 32) within the housing, which supports a magnetic field generator (161). The present invention develops a gripping device in which a support device for an arrangement of a magnetic field generator – for the stroke-dependent triggering of a switching signal in a commercially available magnetic field sensor mounted externally on the housing – is designed and mounted inside the device housing in such a way that it can be easily and securely mounted with minimal installation space and low weight.
