Injection-Molded Foundation Device for Two Post Sizes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing concrete foundation blocks are limited to supporting only one size of post or beam, requiring multiple sizes to be stocked, which increases storage and capital requirements, and they occupy more space than desired.
Innovation Solution
A plastic injection-molded foundation device with a platform, base, inner and outer support walls, and a post recess, allowing support for two different sized posts and beams, featuring tapered channels and ribs for adjustable fit, and a hollow design for improved nestability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple sizes of foundation devices are produced to cater for different sized posts, then customer requirements are met, but storage and capital requirements increase
Solution Approach 1:
The foundation device is designed with adjustable features including expandable arms and reconfigurable support structures that allow a single device to support multiple post and beam sizes. The device can be adjusted to accommodate different dimensional requirements through movable components and adjustable positioning mechanisms, eliminating the need for multiple specialized devices.
Solution Approach 2:
The foundation device incorporates nested structural elements where smaller components can be stored within larger ones when not in use. The adjustable arms and support structures can be collapsed or retracted into the main body of the device, significantly reducing the storage space required compared to multiple separate devices.
2Strength
If concrete foundation blocks are used to provide support, then structural strength is achieved, but the height of the floor must be at least two standard size steps above the ground
Solution Approach 1:
The foundation device replaces static concrete blocks with dynamic, adjustable support structures. The device includes extendable arms and reconfigurable support elements that can be adjusted to provide the necessary structural strength while accommodating varying floor heights. This allows the structure to adapt to different height requirements without compromising load-bearing capacity.
3Length of stationary object
If a plastic injection moulded foundation device is used to support posts or beams, then the profile is lowered allowing decks to be built lower to the ground, but different sized foundation devices must be produced to cater for different sized posts
Solution Approach 1:
The foundation device incorporates dynamic adjustment mechanisms including movable arms and reconfigurable support structures that allow the same device to adapt to different post and beam sizes. The adjustable components enable the device to maintain its low profile while accommodating various dimensional requirements through mechanical adjustment rather than requiring multiple fixed-size devices.

AI summary
A foundation device able to support two different sized posts. The foundation device comprising a platform; a base located below the platform with the base being connected to the platform by an outer support wall; an inner support wall extending upwardly from the platform, the inner support wall being separated into four inner wall sections that define a first beam channel and a second beam channel; and a post recess centrally located within the platform, a floor of the post recess being located lower than that of the platform.
