Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spindles used in devices with spindle nuts face issues with operational stability due to the lack of sufficient bending resistance and protection of weld seams from deformation and contamination, which affects the service life and reliability of the spindle.
Innovation Solution
The introduction of a clamped ring element between the support plate and the spindle body provides mechanical reinforcement, increasing bending resistance and protecting the weld seam from deformation and contamination, allowing for the use of cost-effective materials and preventing contamination of the spindle body thread during laser welding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a thin support plate is used to maintain precision geometry and reduce weight, then manufacturing precision and weight are improved, but bending resistance and structural strength deteriorate
Solution Approach 1:
The patent applies a composite structure by combining the thin support plate with a clamped ring element. The ring element acts as a reinforcing component that provides additional bending resistance and structural strength without compromising the precision geometry of the thin support plate. This composite approach allows the system to achieve both precision and strength simultaneously.
Solution Approach 2:
The clamped ring element adds a dimensional reinforcement by extending radially outward from the spindle body, creating a three-dimensional reinforcement structure. This radial extension provides leverage against bending forces without requiring increased thickness in the support plate, thus maintaining precision while improving strength.
2Ease of manufacture
If conventional welding is used to attach the support plate to the spindle body, then ease of manufacture is improved, but weld seam deformation and contamination of the spindle thread deteriorate
Solution Approach 1:
The clamped ring element serves as an intermediary component between the support plate and spindle body. It acts as a physical barrier that prevents welding beads and contaminants from reaching the spindle thread during the welding process, while still allowing the support plate to be securely attached to the spindle body.
Solution Approach 2:
The clamped ring element is positioned on the spindle body before the welding process begins. This preliminary placement ensures that the spindle thread is protected from contamination before any welding occurs, preventing the need for post-welding cleaning operations.
3Strength
If high-strength materials are used to increase bending resistance, then strength is improved, but manufacturing cost and material weight increase
Solution Approach 1:
Instead of using high-strength materials throughout the entire spindle assembly, the patent applies a composite approach by adding a separate clamped ring element made of high-strength material only where needed for bending resistance. This localized reinforcement maintains overall weight efficiency while providing the necessary strength enhancement.
Solution Approach 2:
The clamped ring element provides localized reinforcement at the critical area where bending forces are applied to the support plate. This local quality enhancement allows the use of standard materials for the main spindle components while providing extra strength only where required, avoiding unnecessary weight increase.

AI summary
A supported spindle for a device equipped with a spindle nut. The supported spindle includes a spindle body extending along its center longitudinal axis, a support plate, which is welded onto the spindle body in such a way that a weld seam formed between the spindle body and the support plate extends around the center longitudinal axis of the spindle body, and a ring element framing a section of the center longitudinal axis of the spindle body, which contacts the support plate on at least one first contact surface of the ring element and contacts the spindle body on at least one second contact surface of the ring element in such a way that the ring element is clamped between the support plate and the spindle body.
