Solution Overview

Problem

Display walls with multiple electronic modules face challenges in reducing visible gaps between modules and managing stress when configured non-planarly, which can lead to increased mechanical stress and instability.

Innovation Solution

An interface system comprising a base structure and a holder structure with tiltable planar surfaces and curved support structures allows for adjustable positioning and orientation of display modules relative to a framework, enabling a curved display wall configuration with reduced stress through tilting and linear displacement mechanisms, and fixation systems to maintain stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If display modules are arranged in a non-planar configuration to create a curved display wall, then the immersive experience for the viewer is increased, but the amount of induced stress in the mechanical structure and display modules increases

Engineering Contradiction:

Improvecurved display wall configurationVSAvoidmechanical stress

Core Design Contradiction:

Adaptability or versatilityVSStress or pressure

Solution Approach 1:

The holder structure is designed with movable components that allow the display modules to dynamically adjust their positions and orientations. The base structure can tilt and rotate relative to the holder, enabling the system to adapt to curved configurations while distributing mechanical stress through controlled movement rather than rigid fixation.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system allows changes in geometric parameters such as tilt angles and rotational positions of display modules. By varying these parameters, the display wall can transition between planar and curved configurations, and the stress distribution can be optimized for each configuration state.

Inventive Principle:

Principle #35Parameter changes

2Manufacturing precision

If mechanical structures are used to adjust each module into a correct position to decrease visible gaps, then the gap visibility is reduced, but the device complexity increases

Engineering Contradiction:

Improvemodule positioning precisionVSAvoidmechanical adjustment structure

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

Multiple adjustment functions are merged into a single integrated holder structure. The holder simultaneously provides tilting, rotating, and positioning capabilities through combined mechanical elements, reducing the number of separate adjustment mechanisms needed while maintaining precise module positioning.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The holder structure is designed as a universal mounting system that can accommodate multiple display modules with different positioning requirements. The same holder design can tilt, rotate, and position modules in various orientations, providing multi-functional capability without requiring separate adjustment mechanisms for each module.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If display modules are arranged at angles to each other to create a curved display wall, then the immersive experience is enhanced, but the stability of the mechanical structure decreases

Engineering Contradiction:

Improveangled module arrangementVSAvoidmechanical structure stability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The mechanical structure incorporates dynamic adjustment capabilities that allow the system to achieve stable configurations in angled arrangements. The movable components enable precise positioning at various angles, and once positioned, the modules are secured to maintain stability in the curved configuration.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The holder structure acts as an intermediary between the fixed framework and the display modules. It absorbs and distributes the mechanical stresses generated by angled arrangements, providing a stable connection that accommodates both the angled configuration and the structural requirements for stability.

Inventive Principle:

Principle #24Intermediary (Mediator)
