Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing actuating devices with a handle secured to a shaft have limited flexibility in attachment positions, restricting precise adaptation to spatial conditions due to a small number of fastening points on the peripheral surface of the attachment element.

Innovation Solution

The handle element is fastened to the front side of the attachment element, which is oriented perpendicularly to the shaft's main axial direction, providing a larger number of adjustable positions and enhancing flexibility by using multiple fastening connections such as threaded holes and screws.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the handle element is fastened on the peripheral surface of the attachment element, then the structure is simple, but the number of fastening points is limited

Engineering Contradiction:

Improvenumber of fastening pointsVSAvoidattachment structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent transitions from fastening on the one-dimensional peripheral surface to fastening on the two-dimensional front side of the attachment element. This dimensional change provides significantly more available area for positioning fastening points, thereby increasing adaptability without substantially increasing structural complexity.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The front side of the attachment element is equipped with multiple threaded holes distributed at different positions, segmenting the fastening options into discrete selectable points. This allows the handle element to be precisely positioned at various locations while maintaining a relatively simple overall attachment structure.

Inventive Principle:

Principle #1Segmentation

2Area of stationary object

If the attachment element has a small diameter, then the device is compact, but the peripheral surface area for fastening is reduced

Engineering Contradiction:

Improvefastening surface areaVSAvoidattachment element size

Core Design Contradiction:

Area of stationary objectVSVolume of moving object

Solution Approach 1:

By moving the fastening surface from the curved peripheral surface to the flat front side of the attachment element, the patent effectively increases the available fastening surface area without increasing the diameter of the attachment element. This maintains device compactness while providing sufficient area for multiple fastening points.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

An actuating device has an actuating element connected in a rotationally-fixed manner to a shaft. The shaft is mounted so that it is rotatable in the housing. The actuating element is pivotable using a hand lever connected to the shaft. The hand lever is formed from an attachment element connected to the shaft and an elongated handle element fastened on the attachment element. The handle element is fastenable at different positions on a front side of the attachment element. The front side of the attachment element is oriented perpendicularly to a main axial direction of the shaft.
