Solution Overview

Problem

Existing LED screens face difficulties in quickly and accurately aligning and securing LED modules due to the need for screw-based fastening mechanisms, which can lead to deformation and increased risk of malfunction during replacement, especially when installed in hard-to-reach locations.

Innovation Solution

The implementation of a retention system using a male-female part configuration with a resilient retention spring that allows for tool-free attachment and detachment of LED modules, providing a consistent and secure pressing force without the risk of over-tightening, thus ensuring accurate alignment and stability without the use of screws.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If screw-based fastening mechanisms are used to secure LED modules, then the LED modules can be firmly attached to the mounting frame, but the risk of deformation increases and the replacement process becomes time-consuming and dangerous

Engineering Contradiction:
Improveattachment strengthVSAvoidmodule replacement ease
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The patent replaces the traditional screw-based mechanical fastening system with a spring-based retention mechanism. The spring retainers engage with the mounting frame to secure LED modules, eliminating the need for screws and screwdrivers. This substitution maintains secure attachment while enabling tool-free installation and replacement, directly resolving the contradiction between attachment strength and ease of operation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the fastening mechanism from a rigid screw system to a resilient spring system. The spring retainers provide continuous contact pressure through elastic deformation, maintaining secure attachment without the risk of over-tightening that can cause deformation. This parameter change from rigid to resilient fastening resolves both the attachment strength requirement and the ease of operation need.

Inventive Principle:
Principle #35Parameter changes

2Strength

If screws are used to fasten LED modules, then the modules can be securely mounted, but the risk of over-tightening and deformation increases

Engineering Contradiction:
Improvemounting securityVSAvoidmodule alignment precision
Core Design Contradiction:
StrengthVSManufacturing precision

Solution Approach 1:

The patent transitions from a rigid screw fastening system to a resilient spring-based system. The spring retainers automatically adjust to the correct mounting pressure through their elastic properties, eliminating the risk of over-tightening that can cause deformation or misalignment. This ensures consistent, precise module alignment while maintaining secure mounting, resolving the contradiction between mounting security and alignment precision.

Inventive Principle:
Principle #35Parameter changes

3Ease of manufacture

If LED modules are mounted high above ground during light shows, then the installation is complete, but the risk of dropping modules and screws during replacement increases

Engineering Contradiction:
Improveinstallation completenessVSAvoidreplacement safety
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent replaces the screw-based fastening system with a spring retainer system that enables tool-free operation. During replacement at height, technicians can securely attach and detach modules using only hands, eliminating the risk of dropping screws and the need for tools that could be lost or cause injury. This maintains installation completeness while dramatically improving replacement safety at height.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Strength

If screw-based fastening is used, then LED modules can be attached, but the process becomes time-consuming and complex

Engineering Contradiction:
Improveattachment capabilityVSAvoidmodule replacement speed
Core Design Contradiction:
StrengthVSProductivity

Solution Approach 1:

The patent substitutes the multi-step screw fastening process with a single-action spring retainer mechanism. Modules can be quickly attached by engaging the spring retainers and secured with a simple pressing motion, eliminating the need for multiple screw operations. This maintains secure attachment capability while dramatically increasing replacement speed and productivity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
