Portable Padlock Tool-Free Battery Replacement Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic ironing locks require tools to replace the energy source, which can cause delays and compromise safety due to the need for a separate fastener to ensure a reliable seal against liquids and dust, especially in occupational safety environments.
Innovation Solution
A portable ironing lock with an electromechanical locking mechanism featuring a housing with an exchange opening and a lid that uses elastic deformable sealing sections to securely seal the energy source, allowing tool-free replacement of the energy source by compressing and deforming the sealing sections upon lid attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate fastener is used to seal the housing opening, then sealing reliability is improved, but device complexity and operation difficulty increase
Solution Approach 1:
The sealing function is merged with the lid itself. The lid incorporates an elastically deformable sealing section that directly forms the seal when the lid is attached to the housing, eliminating the need for separate fasteners or sealing components. This integration resolves the contradiction by maintaining sealing reliability while reducing device complexity.
Solution Approach 2:
The sealing section is designed to be self-sealing through elastic deformation. When the lid is attached to the housing, the sealing section automatically deforms to create a tight seal without requiring additional fastening operations. This self-service mechanism improves sealing reliability while simplifying the device structure and ease of operation.

If a separate fastener is used to ensure seal, then sealing reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The sealing function is merged with the lid itself. The lid incorporates an elastically deformable sealing section that directly forms the seal when the lid is attached to the housing, eliminating the need for separate fasteners or sealing components. This integration resolves the contradiction by maintaining sealing reliability while reducing device complexity.
Solution Approach 2:
The sealing section is designed to be self-sealing through elastic deformation. When the lid is attached to the housing, the sealing section automatically deforms to create a tight seal without requiring additional fastening operations. This self-service mechanism improves sealing reliability while simplifying the device structure and ease of operation.
3Productivity
If tool-free replacement is implemented, then productivity is improved, but sealing reliability may worsen
Solution Approach 1:
The sealing section is designed to be self-sealing through elastic deformation. When the lid is attached to the housing, the sealing section automatically deforms to create a tight seal without requiring additional fastening operations. This self-service mechanism enables tool-free replacement while maintaining sealing reliability.
Solution Approach 2:
The sealing section utilizes elastic deformation as a key parameter change. By designing the sealing section with appropriate elastic properties, it can automatically adapt to the housing opening geometry and create a reliable seal through deformation alone, enabling both tool-free operation and maintained sealing reliability.

AI summary
A portable padlock comprises a lock body, a shackle, and an electromechanical locking mechanism designed to selectively lock the shackle. A power source for the locking mechanism is located in a housing with a service opening through which the power source can be inserted and removed. The padlock includes a cover that can be attached to the housing to close the service opening. The housing or cover has at least one elastically deformable sealing section that forms a circumferential protrusion on a side wall of the housing or cover and is compressible and/or elastically deformable between the cover and the housing when the cover is attached.
