Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing alarm box housings lack a reliable mechanism to ensure secure assembly and disassembly while preventing accidental activation or discharge of the electric battery, and existing solutions do not effectively address the need for easy activation and deactivation of the electronic circuit.
Innovation Solution
The housing features a base and a box with anti-assembly means, including a removable anti-assembly stop and insulating blade that electrically isolates the battery contact until intentionally broken, allowing for secure assembly and activation of the electronic circuit by breaking these weakened parts, enabling contact between the box's contact member and the battery's pad.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If anti-assembly means are provided to prevent accidental activation, then battery safety is improved, but device complexity increases due to additional components
Solution Approach 1:
The patent combines the anti-assembly stop (24) and electrical insulation member (29) into a single integrated component made of electrically insulating material. This merging reduces the number of separate parts while maintaining both the mechanical prevention of accidental activation and the electrical isolation functions, thereby improving reliability without proportionally increasing device complexity.
Solution Approach 2:
The insulating material component serves multiple functions simultaneously: it acts as an electrical insulator to prevent battery discharge, provides mechanical stopping to prevent accidental activation, and serves as a structural element within the housing. This multi-functionality addresses the reliability concern while minimizing the increase in device complexity by using a single component for multiple purposes.
2Ease of operation
If weakened parts are included for easy disassembly, then ease of operation is improved, but strength is reduced
Solution Approach 1:
The housing includes localized weakened parts (25, 26) that segment the overall structure into breakable joints. These segmented weak points allow easy disassembly through controlled breaking while the rest of the housing maintains full structural integrity. The segmentation principle enables differentiated strength distribution where needed for ease of operation without compromising overall housing strength.
3Reliability
If electrical insulation member is interposed to prevent discharge, then battery safety is improved, but device complexity increases
Solution Approach 1:
The electrical insulation member (29) is merged with the anti-assembly stop (24) into a single integrated component. This combination eliminates the need for separate electrical isolation mechanisms, thereby preventing battery discharge through the insulating property of the unified component while avoiding additional complexity from multiple separate parts.
Solution Approach 2:
The insulating material component is made of homogeneous electrically insulating material throughout its structure, providing consistent electrical isolation properties. This homogeneity ensures reliable battery discharge prevention without requiring complex layered structures or multiple materials, thereby maintaining simplicity while improving reliability.

AI summary
A housing comprising a base and a casing adapted to be mounted on the base in a mounted position. The casing (3) is provided with an electrical contact element (20) and has a compartment (16) for receiving a battery (17) comprising at least one electrical contact pad (18), in a position in which this electrical contact pad is in contact with said electrical contact element. The base (2) and the casing (3) are respectively provided with anti-mounting means (24, 27) capable of occupying, relative to each other, an anti-mounting position in which they cooperate and prevent the casing from moving relative to the base up to said mounted position, and a release position in which the base and the casing can be moved up to said mounted position and vice versa.The anti-assembly means (24) of the housing (3) is provided with an electrical isolation element (29) which, in said anti-assembly position, is interposed between the electrical contact element (20) of the housing (3) and the electrical contact pad (18) of the electric battery (17) and which, in said release position, is extracted and permits contact between the electrical contact element of the housing and the electrical contact pad of the electric battery.
