Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pole assemblies inserted into the ground often become skewed due to instability, making it difficult to achieve a vertical orientation.
Innovation Solution
A pole assembly system featuring a hub with enclosed channels and arm assemblies that can rotate, supported by a pin with a scalloped bottom surface, and a finial with a built-in spirit level for alignment, allowing for easy vertical insertion and supporting various accessories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pole is inserted directly into the ground, then the installation process is simple, but the pole becomes skewed and unstable
Solution Approach 1:
The pole assembly is divided into multiple sections that can be connected together, with each section having specific functional features. The base section includes insertion features while upper sections provide stability, allowing the pole to be both easy to install and stable when erected.
Solution Approach 2:
The pole sections are pre-configured with alignment features, connection mechanisms, and stability elements before installation. The base section includes pre-formed insertion features and the upper sections have pre-attached stability components, so that when assembled, the pole automatically achieves vertical stability without requiring complex installation procedures.
2Stability of the object's composition
If the pole is braced or inserted in concrete to ensure stability, then the pole can withstand transverse forces, but the installation becomes difficult and time-consuming
Solution Approach 1:
The pole is segmented into a base section and upper sections, with the base section containing integrated stability features such as bracing elements or expansion mechanisms that deploy after insertion. This eliminates the need for concrete pouring while maintaining stability and allowing quick installation.
Solution Approach 2:
The pole assembly includes dynamic stability mechanisms that activate after insertion, such as expandable base sections or deployable bracing elements. These features allow the pole to adapt to the ground conditions and achieve stability without requiring time-consuming concrete work, thereby maintaining high installation productivity.
3Ease of manufacture
If the pole is made as a single unitary structure, then the manufacturing process is simple, but the pole cannot be easily adjusted or configured with accessories
Solution Approach 1:
The pole is divided into multiple standardized sections with uniform connection interfaces. Each section can be manufactured independently using simple processes, then assembled in various configurations.Accessory mounting points are included on each section, allowing flexible accessory placement without complex manufacturing.
Solution Approach 2:
The pole sections are designed with universal connection features and standardized accessory mounting points that can accommodate different types of accessories. The same basic section design serves multiple functions - structural support, accessory mounting, and potential reconfiguration - thereby maintaining manufacturing simplicity while maximizing versatility.
4Strength
If the pole sections are connected with mechanical fasteners, then the connection strength is high, but the assembly process becomes more complex
Solution Approach 1:
The connection mechanism merges multiple functions into a single operation - alignment, locking, and strengthening are achieved through one integrated connection action. The base section and upper sections have complementary features that automatically align and lock together, providing strong mechanical connection without requiring separate fastening steps or complex assembly procedures.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures the pole is inserted vertically and securely, with the ability to rotate if necessary, and supports multiple accessories like bird feeders and trays, enhancing stability and usability.
Implementation Method 1
the finial having a level incorporated therein
Implementation Method 2
The hub can rotate if a sufficient force is applied thereto. This may be accomplished by means of a scalloped bottom surface upon which the pin will rest.
