Solution Overview

Problem

Conventional holders with suckers are limited to flat and smooth surfaces, failing to securely attach to curved or patterned surfaces, leading to instability during vibrations, posing safety risks, especially in vehicles.

Innovation Solution

A holder with a deformable body and adhesive layer, combined with a locking module and rod, allows for secure attachment to non-flat surfaces by forming a low-pressure space, using a deformable pad filled with fluid or particles to conform to surface contours and an adjustable locking mechanism for enhanced stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional sucker with a planar rim is used, then the holder can be mounted on flat and smooth surfaces, but it cannot be mounted on curved or patterned surfaces

Engineering Contradiction:

Improvesurface compatibilityVSAvoidsucker structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies a flexible deformable body (such as a rubber or silicone pad) as the contact surface of the sucker, replacing the conventional rigid planar rim. This flexible material can elastically deform to conform to curved or patterned surfaces, enabling the holder to be mounted on diverse surface geometries while maintaining the simplicity of the overall sucker structure

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The patent changes the physical parameters of the sucker's contact surface by using a deformable material with specific elastic properties. The deformable body can change its shape and pressure distribution according to the surface it contacts, allowing adaptation to different surface types without complicating the device structure

Inventive Principle:

Principle #35Parameter changes

2Reliability

If a holder is mounted on a non-planar surface with a conventional sucker, then the low-pressure space cannot be formed, but adding a deformable body increases the complexity of the sucker structure

Engineering Contradiction:

Improvemounting stabilityVSAvoidsucker structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The deformable body acts as a flexible interface that can conform to non-planar surfaces, enabling the formation of a sealed low-pressure space between the sucker and the object surface. This flexible adaptation ensures reliable mounting on curved or patterned surfaces while keeping the structural addition minimal and functional

Inventive Principle:

Principle #30Flexible shells and thin films

3Stability of the object's composition

If a conventional sucker is used on a patterned surface, then the holder can be mounted, but it cannot maintain the low-pressure space under vibration, leading to separation

Engineering Contradiction:

Improveattachment stabilityVSAvoidsucker structure

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The deformable body provides continuous elastic contact with patterned surfaces, maintaining the seal of the low-pressure space even under vibrational conditions. The flexibility allows the sucker to adapt to surface irregularities and maintain stable attachment without requiring additional complex stabilization mechanisms

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The deformable body introduces dynamic adaptability to the sucker structure, allowing it to continuously adjust its shape and pressure distribution in response to vibrations and surface variations. This dynamic response maintains the integrity of the low-pressure space and prevents separation during operation

Inventive Principle:

Principle #15Dynamics

AI summary

A holder and a sucker thereof for mounting onto the surface of an object are provided. The sucker has an adhesive layer and a deformable body which is disposed on the edge of the adhesive layer. The holder further includes a rod and a locking module. An end of the rod is connected to the sucker. The locking module is disposed on the sucker and is adapted to lift the rod to form a low pressure space. Thus, the holder and the sucker can be positioned onto the surface of the object.
