Elastic Pad Support Plate with Rigid Frame for Creep Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing intermediate soles for outdoor equipment, when installed on prefabricated anchor blocks with grooves, tend to creep downwards and are difficult to slip onto threaded rods due to their deformable nature.
Innovation Solution
A sole comprising elastic pads made of a flexible material and a rigid frame, where the frame prevents deformation and facilitates assembly by limiting creep, allowing for adjustment of the equipment's orientation through compression of the pads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a compressible midsole is used to adjust verticality, then ease of operation is improved, but the midsole creeps locally downwards towards grooves and becomes difficult to install
Solution Approach 1:
The sole combines elastic material (for compressibility and adjustment) with a rigid frame structure (for creep resistance). This composite construction allows the sole to maintain its shape and resist downward creep into grooves while still enabling verticality adjustment through controlled compression of the elastic portions.
Solution Approach 2:
The sole is divided into distinct functional zones: elastic compressible portions for adjustment and rigid frame elements for structural support. This segmentation allows each part to perform its specific function optimally - the elastic parts provide adjustment capability while the rigid frame prevents unwanted deformation and creep.
2Adaptability or versatility
If a deformable intermediate element is used, then adaptability is improved, but ease of operation deteriorates due to difficulty in slipping onto threaded rods
Solution Approach 1:
The sole is divided into distinct functional zones: elastic compressible portions for adjustment and rigid frame elements for structural support. This segmentation allows each part to perform its specific function optimally - the elastic parts provide adjustment capability while the rigid frame prevents unwanted deformation and creep.
Solution Approach 2:
The sole utilizes material with different mechanical parameters - elastic regions for deformation and rigid regions for stability. By changing the physical state and mechanical properties of different parts, the sole achieves both adaptability for orientation adjustment and ease of installation through the rigid portions.
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
The sole is easy to use, has a low risk of undesirable creep, and provides strong and durable support while allowing for adjustment of the equipment's orientation relative to the anchor block.
Implementation Method 1
each elastic pad being provided with a passage orifice which passes through the elastic pad from the upper support side to the lower support side... the frame being made of a second material distinct from the first material and having greater rigidity to that of the first material

AI summary
This base (1), designed to be interposed between a base of outdoor equipment and an anchoring mass of this base in the ground, comprises: - several elastic pads (23) made of a first material, the elastic pads each having an upper bearing side (27) and a lower bearing side (29) opposite the upper bearing side, each elastic pad being provided with a passage orifice (31) which passes through the elastic pad from the upper bearing side to the lower bearing side, and - a support frame (25) for the elastic pads, the frame being made of a second material distinct from the first material and having a rigidity greater than that of the first material.
