Blackout Housing Battery Bracket for Fast Secure Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blackout devices require a significant number of operations and costly supports to mount batteries, which are inefficient and time-consuming for installers.
Innovation Solution
A blackout device design with supports that securely hold the battery in place using a curved arm between the battery and the inner surfaces of the housing walls, minimizing installation operations and costs by allowing the battery to be positioned close to the corners of the housing, thus optimizing space and preventing contact with the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If elastic snap-fit supports with elastic bands and hooks are used to hold the battery, then the battery is securely positioned inside the housing, but the number of installation operations increases and installation cost increases
Solution Approach 1:
The patent removes the elastic band and hook components from the support structure, extracting only the essential function of holding the battery. The support becomes a simple L-shaped bracket that relies on its geometry and the battery's own weight for retention, eliminating unnecessary fastening mechanisms.
Solution Approach 2:
The support structure is designed to automatically hold the battery in place through its L-shape geometry without requiring additional fastening operations. The battery's weight and the support's configuration create a self-locking mechanism where the battery naturally rests against the vertical arm and is prevented from falling by the horizontal arm.
2Reliability
If multiple fastening operations are performed to secure the battery, then the battery is firmly fixed inside the housing, but the installation time increases
Solution Approach 1:
The support is divided into two functional arms: a vertical arm for mounting to the housing wall and a horizontal arm for contacting the battery. This segmentation allows each arm to perform its specific function independently, simplifying the overall installation process to just two steps: mounting the support and placing the battery.
Solution Approach 2:
The support structure is pre-configured in an L-shape that is ready to receive the battery immediately upon mounting. The geometry is designed in advance to automatically position and secure the battery without requiring additional adjustment or fastening operations during installation.
3Device complexity
If the support structure is simplified to reduce installation complexity, then installation operations are reduced, but the battery positioning security may be compromised
Solution Approach 1:
The horizontal arm of the support features a curved lower surface that conforms to the cylindrical shape of the battery. This curvature creates a stable contact interface that naturally positions the battery and prevents it from rolling or shifting, providing secure positioning without complex fastening mechanisms.
Solution Approach 2:
The support structure concentrates its securing function at the critical contact point between the horizontal arm and the battery. The curved lower surface of the horizontal arm provides localized adaptive contact that matches the battery's geometry, ensuring secure positioning at the most important location while keeping the rest of the structure simple.

AI summary
A blackout device comprises a housing (9), a screen (2), a winding tube, and an electrical energy storage device (33), including a battery (24) and two brackets (37). Each bracket (37) is fixed against a first inner surface (9ai) of a first wall (9a) of the housing (9). A first surface (41a) of a first arm (41) of each bracket (37) rests against the first inner surface (9ai) of the first wall (9a). A second surface (42a) of a second arm (42) of each bracket (37) is curved and rests against an outer surface (24e) of the battery (24). The second arm (42) is positioned between the battery (24) and the screen (2). In addition, the battery (24) is held against the first inner surface (9ai) of the first wall (9a) and against a second inner surface (9bi) of a second wall (9b) of the chest (9), by means of the second surface (42a) of the second arm (42).
