Support Arm Connection With Axial Stop And Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support arm systems in industrial environments, such as production machines and control desks, are complex, space-intensive, and offer limited freedom of movement.
Innovation Solution
A support arm connection featuring a housing ring and a support arm ring, with a radially inwardly projecting shoulder forming an axial stop, allowing for a compact, flexible, and high-pivoting design using few components, and enabling easy definition of pivoting range with an axially projecting lug and locking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex support arm systems are used to achieve stability and positioning, then positioning reliability is improved, but device complexity increases
Solution Approach 1:
The support arm system is divided into distinct functional segments: a support arm with integrated locking mechanism, a support arm receptacle with shoulder stop, and optional locking means. This segmentation allows each component to perform its specific function independently while maintaining overall system reliability without excessive complexity.
Solution Approach 2:
The support arm incorporates a self-contained locking mechanism that automatically engages with the receptacle shoulder, allowing the arm to secure itself without requiring additional complex external locking systems. The worm screws enable the arm to lock and unlock its own position independently.
2Strength
If traditional support arm systems are used to ensure structural strength, then strength is improved, but the space required increases
Solution Approach 1:
The support arm ring is received within the support arm receptacle, with the receptacle shoulder providing internal support. This nested arrangement allows the structural support functions to be contained within a compact volume, eliminating the need for external bracing structures that would increase space requirements.
Solution Approach 2:
The receptacle shoulder provides structural support in the radial direction, while the support arm extends in the axial direction. This dimensional arrangement allows the structural strength to be achieved through spatial optimization rather than increasing component size in a single direction.
3Stability of the object's composition
If conventional mounting systems are used to provide stability, then stability is improved, but freedom of movement is limited
Solution Approach 1:
The support arm system transitions from a fixed mounting to a dynamic system where the arm can pivot and rotate within the receptacle. The locking mechanism provides stability only when needed, allowing free movement during adjustment, thus combining stability with adaptability.
Solution Approach 2:
The system allows changing of operational parameters by enabling the support arm to assume multiple angular positions and orientations. The receptacle shoulder provides a reference position, while the locking means allows the arm to be positioned at various angles to accommodate different working requirements.
4Reliability
If multiple components are used to achieve secure positioning, then positioning reliability is improved, but the number of components increases
Solution Approach 1:
The locking mechanism is merged into the support arm itself rather than being a separate external component. The arm incorporates the locking interface that engages with the receptacle shoulder, and the worm screws are integrated into the arm structure, reducing the total component count while maintaining secure positioning.
Solution Approach 2:
The receptacle shoulder serves multiple functions: it provides a physical stop defining the retraction position, provides a surface for the locking mechanism to engage, and defines the pivot axis for the support arm. This multi-functionality eliminates the need for separate components for each function.

AI summary
Support arm connection for a component includes a support arm holder disposed on the component and a support arm having an end and being insertable into the support arm holder. A housing ring is disposed on the support arm. A support arm ring is disposed on the support arm. The housing ring is axially located further away from the end of the support arm than the support arm ring. A radially inwardly protruding shoulder of the support arm holder includes a stop surface. When the support arm is inserted into and mounted to the support arm holder, the stop surface limits axial movement of the support arm ring, the housing ring is fixedly secured to the support arm holder and the support arm ring is fixedly secured to the support arm.
