Solution Overview

Problem

Existing elevated building surface systems, such as decks and walkways, face challenges in accommodating varying surface contours and supporting heavy or large tiles, as they often require multiple pedestals and lack efficient height adjustment mechanisms, which can lead to instability and uneven surfaces.

Innovation Solution

A support pedestal system with an adjustable apparatus comprising interconnected connectors and a shaft, allowing for vertical adjustment and tilting to level building surface components, featuring a base and support plate configuration with threaded engagement for precise height control and stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If multiple pedestals are used to support heavy or large tiles, then the load-bearing capacity is improved, but the device complexity and installation difficulty increase

Engineering Contradiction:
Improveload-bearing capacityVSAvoiddevice complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The pedestal is divided into multiple independent components: a base member with base plate, a support member with support plate, an adjustment apparatus with connectors and shaft, and optional extender members. This segmentation allows each component to be optimized for its specific function while enabling easy assembly and disassembly, reducing installation complexity despite using multiple pedestals for heavy tiles

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The pedestal incorporates an adjustable height mechanism through the adjustment apparatus that allows the support member to be positioned at different heights relative to the base member. This dynamic adjustment capability enables the pedestal to adapt to uneven surfaces and accommodate varying tile sizes and weights, maintaining stability without requiring additional pedestals

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If adjustable height pedestals are used to accommodate surface contour variations, then the adaptability is improved, but the device complexity increases

Engineering Contradiction:
ImproveadaptabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adjustment apparatus enables dynamic height adjustment by allowing rotational movement of the support member relative to the base member through threaded engagement of connectors with the shaft. This mechanical dynamic system provides continuous height variation capability to accommodate any surface contour while maintaining a relatively simple two-member structure

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The pedestal changes its key parameter (height) through the adjustment apparatus that modifies the vertical distance between the base plate and support plate. By varying this dimensional parameter through mechanical adjustment, the pedestal adapts to different surface elevations without requiring complex electronic sensors or actuators

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If extender members are added to increase pedestal height, then the adaptability is improved, but the device complexity and number of components increase

Engineering Contradiction:
Improveheight rangeVSAvoidnumber of components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The extender member is designed to be nested within or attached to the existing adjustment apparatus structure. The extender can be positioned inside the adjustment apparatus housing or attached to the shaft, utilizing the existing mechanical interface to extend the height range without requiring a completely separate adjustment mechanism, thus minimizing additional complexity

Inventive Principle:
Principle #7Nested doll (Nesting)
