Adhesive Security Cover for Portable Battery Compartment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic items, such as watches, pose a risk as young children can inadvertently remove the battery cover, gaining access to the battery compartment and potentially leading to battery ingestion.
Innovation Solution
A security device is rigidly connected to the portable electronic item using adhesive bonding, which covers the indentation on the cover, preventing the introduction of a tool to rotate the cover and remove it from the casing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cover has a simple indentation shape to facilitate easy battery replacement, then the ease of operation is improved, but the safety against unauthorized access by children deteriorates
Solution Approach 1:
A security device acts as an intermediary element between the indentation and the external environment. This device covers the indentation while maintaining the coupling mechanism's functionality for authorized users, thereby preventing children from accessing the battery compartment without requiring a specific tool.
Solution Approach 2:
The security device is divided into separate functional components: a cover portion that blocks the indentation from view and access, and a coupling mechanism that remains functional for authorized battery replacement. This segmentation allows the device to simultaneously provide safety and ease of operation for legitimate users.
2Ease of manufacture
If the indentation is made accessible for tool insertion, then the ease of manufacture and battery replacement is improved, but the reliability of preventing battery ingestion deteriorates
Solution Approach 1:
The security device serves as a protective intermediary that does not interfere with the coupling mechanism's functionality for authorized users, while simultaneously blocking access for children. The device maintains the indentation's operational integrity while preventing unauthorized access, thereby ensuring reliability in preventing battery ingestion.
3Productivity
If the cover can be quickly opened without a specific tool, then the productivity of battery replacement is improved, but the safety against child access deteriorates
Solution Approach 1:
The security device is designed as an intermediary that does not impede the quick-opening capability for authorized users. The coupling mechanism remains fully functional for rapid battery replacement, while the security device blocks access for children, thereby maintaining productivity while enhancing safety.
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 security device effectively prevents unauthorized access to the battery compartment by rendering the indentation unusable, thereby ensuring the cover cannot be easily removed, especially by young children.

AI summary
A portable electronic item (100) including: a casing (10) having a compartment (11) for housing a removable electrical power source (2); a cover (20) including first coupling elements (23a) that cooperate with second coupling elements (23b) provided on the casing (10) to rigidly connect the cover (20) to the casing (10) by relative rotation. The cover (20) has an indentation (22) in an outer face (21) for receiving a tool for rotating the cover (20). A security device (30, 30′) is rigidly connected by adhesive bonding to the portable electronic item to at least partially cover the indentation (22) of the cover (20) of the compartment (11), so as to prevent the introduction of a tool for rotating the cover (20) and removing it from the casing (10).
