Height-Adjustable Conveyor Belt Without Stabilizing Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conveyor systems for discrete goods face limitations in providing all-round access to the conveyed goods due to stabilizing frames and stiffening elements, restricting flexibility and space usage.
Innovation Solution
The conveyor system employs height-adjustable belt bodies using lifting columns without stabilizing frames, allowing for variable height adjustment via spindles and spindle nuts, and eliminates longitudinal connectors to enhance accessibility, enabling more compact and space-saving designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If stabilizing frames and stiffening elements are used to support the belt bodies, then the structural stability is improved, but the accessibility to the conveyed goods is restricted
Solution Approach 1:
The patent removes the stabilizing frames and stiffening elements from the conveyor system, extracting the problematic structural components that blocked access to goods. The belt bodies are supported directly by the conveyor structure without intermediate frames, eliminating the accessibility barrier while maintaining stability through the lifting column mechanism.
Solution Approach 2:
The patent transitions from a two-dimensional frame-based support structure to a three-dimensional space-utilizing design where lifting columns provide vertical support. This dimensional change allows processing tools to access goods from multiple angles (front, back, sides) without being blocked by horizontal frame elements.
2Stability of the object's composition
If longitudinal connectors are used to support lifting columns, then the structural stability is improved, but the space for positioning processing tools is reduced
Solution Approach 1:
The patent removes longitudinal connectors from the system, extracting the structural elements that consumed valuable space. The lifting columns are supported directly by the base frame without intermediate longitudinal connectors, freeing up the space between columns for positioning processing tools and accessing goods.
Solution Approach 2:
The patent employs a minimalist structural approach where thin, flexible belt bodies replace rigid frame structures. The belt bodies can conform to the space available and are supported by vertically oriented lifting columns, maximizing the usable horizontal space for processing operations.
3Adaptability or versatility
If height-adjustable belt bodies are implemented, then the adaptability to different goods is improved, but the device complexity increases
Solution Approach 1:
The patent implements dynamic height adjustment of belt bodies through lifting columns that can be raised or lowered to accommodate goods of varying heights. This dynamic capability allows the same conveyor system to handle different product specifications without requiring manual reconfiguration or additional equipment.
Solution Approach 2:
The lifting column mechanism serves multiple functions: it supports the belt body, enables height adjustment for different goods, and provides a stable mounting point for processing tools. This multi-functionality reduces overall device complexity by consolidating several functions into a single structural element.

Implementation Method 1
each lifting column has a spindle 5 arranged on it, which can move a spindle nut 4 seated on the spindle up or down in the Z direction by rotating about its axis of rotation running in the Z direction
