Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional dock construction methods face limitations such as lengthy erection times, difficulties with varying seabed conditions, and imprecise pile lane positioning due to limited reach of foundation equipment designed for solid ground, leading to inefficient and non-optimal deck structures.
Innovation Solution
A dock building apparatus featuring a cantilever arm with a lifting device and foundation building tool, allowing for precise X-Y positioning of piles and deck installation, enabling the construction of docks from the shore with improved reach and efficiency, potentially eliminating the need for marine works.

Engineering Contradiction Analysis
1Length of moving object
If traditional foundation building apparatus is used, then equipment can be installed on solid ground, but reach is limited and cannot access construction area effectively
Solution Approach 1:
The apparatus transitions from ground-based operation to water-based operation by positioning the cantilever arm over the construction area. The support structure extends into the water, allowing the foundation building tool to reach and install piles directly in the construction area, effectively adding a spatial dimension to the equipment's reach capability.
Solution Approach 2:
The water is used as an intermediary medium to support the cantilever arm structure. By positioning the support structure in the water rather than on land, the apparatus can bridge the gap between the shore and the construction area, enabling foundation building operations in areas that were previously inaccessible.
2Productivity
If traditional methods are used, then construction can proceed, but erection time is lengthy and efficiency is low
Solution Approach 1:
The apparatus is pre-positioned on the shore with the cantilever arm extended over the construction area before pile installation begins. This preliminary positioning eliminates the need for time-consuming on-site assembly and allows immediate commencement of foundation building operations, significantly reducing erection time.
Solution Approach 2:
The apparatus enables continuous operation by allowing the foundation building tool to work continuously from the shore-based position over the construction area. There are no interruptions for repositioning equipment or setting up temporary structures, maintaining continuous productive action throughout the construction process.
3Manufacturing precision
If foundation equipment is designed for solid ground, then operation is simplified, but positioning precision is insufficient for optimal deck structure
Solution Approach 1:
The apparatus incorporates positioning systems that provide feedback on the location of the foundation building tool relative to the construction area. This feedback mechanism enables precise positioning of piles by adjusting the tool's position along the cantilever arm, ensuring accurate placement for optimal deck structure while managing system complexity through controlled feedback loops.

AI summary
A dock building apparatus comprises a cantilever arm (11) having a first portion configured to be supported on a ground area and a second portion for overhanging a construction area. The cantilever arm (11) is displaceable perpendicularly to the length of the cantilever arm. The apparatus further includes a lifting device (19) movable along the cantilever arm for bringing construction materials including foundation members from the ground area to the second portion of the cantilever arm, and a foundation building tool (15) movable along the cantilever arm for installing the foundation members in the construction area.
