Sliding Battery Lid Locking Mechanism for Wear-Stable Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The remote control device described in PTL 1 has a problem where the battery lid is easily removed due to wear of the engaging claw portion, leading to instability in the lid's attachment.
Innovation Solution
The operating device features a housing with a lid member that slides for attachment and detachment, and a locking member with a mounting portion, hinge portion, operating portion, and regulating portion. The regulating portion restricts the lid's sliding direction and moves with the operating portion to facilitate attachment and prevent unintentional detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an engaging claw portion is used to lock the battery lid, then the lid can be securely attached, but the attachment becomes unstable due to wear over time
Solution Approach 1:
The locking member is designed to rotate between a locked position (where the locking protrusion engages the locking recess) and an unlocked position (where the regulating portion contacts the lid member to prevent removal). This dynamic mechanism allows the locking state to be actively controlled and reset, overcoming the degradation issue of static engaging claws that wear over time.
Solution Approach 2:
The regulating portion acts as an intermediary element between the locking member and the lid member. When in contact with the lid member, it prevents unintended removal by providing an additional constraint, while not interfering with the primary locking engagement between the locking protrusion and locking recess.
2Reliability
If a locking mechanism is added to prevent wear-related detachment, then attachment stability improves, but device complexity increases
Solution Approach 1:
The locking member performs multiple functions: it provides the primary locking engagement through the locking protrusion and recess, controls the locked/unlocked state through rotation, and prevents unintended removal through the regulating portion. This multi-functionality is achieved within a single integrated component, avoiding the need for separate mechanisms for each function.
Solution Approach 2:
The locking protrusion, regulating portion, and rotation capability are integrated into a single locking member that is rotatably coupled to the housing body. This consolidation reduces the number of separate parts compared to having independent locking and regulating components, thereby managing complexity while achieving reliable attachment.
3Reliability
If the regulating portion continuously contacts the lid member, then unintended detachment is prevented, but attachment and detachment operations become difficult
Solution Approach 1:
The contact state between the regulating portion and the lid member is dynamically controlled through rotation of the locking member. During normal operation, the regulating portion contacts the lid member to prevent unintended detachment. During detachment operation, the locking member is rotated to move the regulating portion away, allowing easy removal. This dynamic switching resolves the contradiction between continuous constraint and operational ease.

Function Achieved in This Case
This configuration ensures the lid member is stably attached and prevents unintentional detachment, maintaining the battery lid's secure position over the battery installation portion.
Implementation Method 1
a hinge portion connected to the mounting portion, an operating portion that is connected to the hinge portion, moves around the hinge portion
