Door Display Retaining Clip Assembly for Secure Exterior Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for mounting displays on doors are insecure, as they can be easily removed by anyone with access to the exterior, and fail to adequately secure the display against door motion or disturbances.
Innovation Solution
A device with a display retaining assembly and attachment clips that apply a load to securely engage the display against the door, using a combination of side walls, end walls, and arm structures, and optionally a spring or frame assembly to ensure stability, making it difficult for external manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If simple fasteners or taping methods are used to attach the display to the exterior of the door, then the device is easy to install and remove, but the display can be easily removed by anyone with access to the exterior of the door
Solution Approach 1:
The mounting device is divided into multiple components: attachment clips with side walls and end walls, a display retaining assembly, and optional spring elements. These segmented parts work together to create a secure mounting system that distributes forces across multiple engagement points, making the display difficult to remove while maintaining ease of installation through modular assembly.
Solution Approach 2:
The attachment clips are designed with nested structural elements where side walls and end walls form interlocking configurations. The display retaining assembly fits within the framework created by the clips, creating a nested structure that secures the display firmly to the door while allowing straightforward installation and removal by authorized personnel.
2Device complexity
If simple fasteners are used to secure the display, then the device complexity is low, but the display is not adequately secured against door motion or disturbance
Solution Approach 1:
The mounting device incorporates local quality enhancements through the use of rigid side walls and end walls in the attachment clips, strategically positioned to engage with the door structure at critical points. The display retaining assembly provides localized reinforcement where the display contacts the door, ensuring stability against motion without requiring complex structural elements throughout the entire device.
Solution Approach 2:
The attachment clips feature curved or angled surfaces on the side walls and end walls that conform to the door geometry, creating optimal contact points. This curvature allows the clips to engage securely with the door surface while distributing mechanical stresses, enhancing stability against door motion without adding significant structural complexity.
3Reliability
If a secure mounting device with multiple clips and retaining assemblies is used, then the display is securely mounted against the door, but the device complexity increases
Solution Approach 1:
The attachment clips and display retaining assembly are designed to work as an integrated system rather than separate components. The clips incorporate both side wall and end wall structures in single units, and the retaining assembly merges multiple retention functions into one cohesive structure. This merging reduces the effective number of discrete parts while maintaining high security of mounting.
Solution Approach 2:
The attachment clips serve multiple functions simultaneously: they provide structural support, create engagement points with the door, and form part of the display retention mechanism. The side walls and end walls each contribute to different aspects of security, allowing the device to achieve high reliability without proportionally increasing component count.
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 device effectively secures displays to doors, preventing removal by external individuals and ensuring the display remains in place despite door motion or disturbances, providing a robust and secure mounting solution.
Implementation Method 1
The display retaining assembly may comprise a rod member having a spring attached to an end thereof to form a rod-spring combination
Implementation Method 2
The display retaining assembly is configured to apply a load such that the display retaining assembly causes the first side wall to engages a first surface of the door, the second side wall to engage a second side of the door, and urges the end wall against a side of said door

AI summary
A device for securing a display to a door utilizes attachment clips which attach to the door. The attachment clips each have a first side wall, a second wall and an end wall which extends between the first side wall and the second side wall. An arm is attached to the first side wall. The arm is attached to a display retaining assembly which is configured, upon installation, to retain the display against the door, where the display retaining assembly applies a load which causes the first side wall to engage a first surface of the door and the second side wall to engage a second side of the door, thereby urging the end wall against a side of the door.
