Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mast connection systems to ground-based mast bases complicate maintenance work, requiring expensive safety measures at heights or complex crane operations, and often disrupt traffic routes due to limited accessibility.
Innovation Solution
A device allowing the mast to be connected to a mast base with a pivotable tilting plate and base plate, enabling controlled tilting and rotation of the mast relative to the base, facilitating maintenance without the need for crane access and minimizing traffic disruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the mast is kept erected for maintenance work, then operational continuity is maintained, but safety risks and cost increase due to strict safety requirements at heights
Solution Approach 1:
The connection between mast and mast base is made dynamically adjustable through a tilting plate that can pivot between a parallel position (mast erected) and a tilted position (mast lowered). The first fastening device allows switching between fixed and movable states, enabling maintenance at ground level while preserving operational continuity when erected.
2Reliability
If the mast is lowered with a crane for maintenance, then safety risks are reduced, but device complexity and accessibility requirements increase
Solution Approach 1:
The tilting plate mechanism enables the mast to be lowered and raised using its own structure and the pivotable connection, without requiring external crane assistance. The rotational guide and fastening devices allow the mast to be positioned and secured independently, simplifying maintenance operations.
3Reliability
If the mast is lowered for maintenance, then safety improves, but traffic route disruptions increase due to crane access requirements
Solution Approach 1:
The self-contained tilting mechanism eliminates the need for crane access, allowing maintenance to be performed without closing traffic routes or securing large areas. The mast can be tilted independently at its base location without external equipment intervention.
4Stability of the object's composition
If a fixed connection is used between mast and base, then structural stability is maintained, but maintenance accessibility deteriorates
Solution Approach 1:
The connection system transitions from a purely fixed state to a dynamic system where the tilting plate can pivot to change the mast's position. The first fastening device provides fixed connection during normal operation and enables controlled tilting during maintenance, combining stability with accessibility.
5Ease of operation
If rotation about longitudinal axis is allowed during maintenance, then accessibility to all mast sides improves, but control and positioning complexity increases
Solution Approach 1:
The rotational guide acts as an intermediary mechanism between the mast and tilting plate, providing controlled rotation about the longitudinal axis. This intermediary component enables smooth rotational movement while maintaining positional control, facilitating access to all mast sides without excessive complexity.
