Modular Stand for Rod-Shaped Objects with Interchangeable Positioning Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stands for vertical positioning of rod-shaped objects are limited in their ability to be positioned on various surfaces and can only accommodate specific rod-shaped objects due to fixed ground spikes and receiving sleeves, making them unsuitable for hard surfaces and restricting versatility.
Innovation Solution
A stand with a ring-shaped or disc-shaped base plate featuring a central passage and circumferential passages, allowing for interchangeable positioning elements such as ground spikes and feet, and a detachable receiving sleeve that can be adjusted for different applications, enabling use on various surfaces and accommodating different rod-shaped objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ground spikes are welded to the stand, then the stand can be fixed in soft soil, but the stand cannot be positioned on hard surfaces and cannot be easily exchanged
Solution Approach 1:
The stand is divided into separate functional components: a base plate with mounting holes, detachable positioning elements (ground spikes or feet), and a receiving sleeve. This segmentation allows the positioning elements to be exchanged based on surface conditions, resolving the contradiction between fixed grounding capability and surface adaptability.
Solution Approach 2:
The base plate serves multiple functions: it provides the mounting structure for positioning elements, serves as the foundation for the receiving sleeve, and can accommodate different types of positioning elements (ground spikes for soft soil, feet for hard surfaces). This multi-functionality enables the stand to adapt to various surfaces while maintaining reliable fixing.
2Reliability
If ground spikes are welded to the stand, then the stand can be secured in soft soil, but the stand cannot be easily stored when not in use
Solution Approach 1:
The positioning elements (ground spikes or feet) are detachable from the base plate, allowing them to be removed and stored separately. This segmentation enables compact storage when the stand is not in use, as only the base plate and receiving sleeve need to be stored, significantly reducing the storage volume required.
Solution Approach 2:
The positioning elements are extracted from the permanent structure and made as separate, detachable components. This extraction allows the main body of the stand (base plate with receiving sleeve) to be stored in a compact form, while the positioning elements can be stored separately or attached only when needed for use.
3Reliability
If a fixed receiving sleeve is used, then the stand can secure specific rod-shaped objects, but the selection of rod-shaped objects is limited
Solution Approach 1:
The receiving sleeve is designed as a separate, detachable component from the base plate. This segmentation allows the receiving sleeve to be exchanged for different sizes and types to accommodate various rod-shaped objects, while maintaining reliable securing capability through the standardized interface with the base plate.
Solution Approach 2:
The base plate provides a universal mounting interface that can accommodate different types and sizes of receiving sleeves. This universality enables the stand to secure a wide variety of rod-shaped objects by simply changing the receiving sleeve, while maintaining reliable fixing through the consistent base plate connection.
4Ease of manufacture
If the stand is designed with fixed components, then the manufacturing process is simple, but the stand cannot be adapted for different applications
Solution Approach 1:
The stand is manufactured as segmented components (base plate, positioning elements, receiving sleeve) that can be produced independently using simple processes, then assembled when needed. This segmentation maintains manufacturing simplicity while enabling application flexibility, as components can be produced in standard sizes and configured for different uses.
Solution Approach 2:
The base plate is designed as a universal component with standardized mounting holes and interfaces that can accommodate various positioning elements and receiving sleeves. This universality is achieved through simple standardized manufacturing processes, allowing the same base plate to support multiple applications without complicating the manufacturing of individual components.

AI summary
The invention relates to a stand (1) for vertically positioning a rod-shaped object, comprising: - a ring- or disc-shaped base plate (2), wherein a central passage (8) is formed in the base plate (2) and at least three further passages (3, 3', 3", 3‴), preferably equidistant from each other, are formed along the circumference, preferably near the edge; - a receiving sleeve (4) detachably arranged in or on the central passage (8) of the base plate (2) for inserting and fixing the rod-shaped object, wherein a principal extension direction of the receiving sleeve (4) is orthogonal to a principal extension plane of the base plate (2); - at least three positioning elements, wherein the positioning elements are detachably connected to the base plate (2) in or on the further circumferential passages (3, 3', 3", 3‴), wherein the positioning elements, in the assembled state, face away from a side of the base plate opposite the receiving sleeve (4).
