Foldable Display Holder Locking Structure Against Self-Loosening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable ceiling-mounted display device holders available in the market tend to loosen on their own, posing safety hazards, especially in recreational vehicles and earthquake-prone environments.
Innovation Solution
A display device holder with a locking device that includes a main body, position-limiting rods, an elastic member, and a triggering member, allowing the holder to securely switch between folded and unfolded states, preventing loosening and ensuring stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a foldable holder is used to facilitate easy storage and save space, then the holder can be folded for compact storage, but the holder tends to loosen on its own causing safety hazards
Solution Approach 1:
The locking device automatically locks the supporting member in the unfolded state through self-service mechanism. The elastic member continuously exerts force to maintain the locked position without requiring external intervention, making the holder self-sufficient in maintaining its operational state
Solution Approach 2:
The locking device applies preliminary anti-action by pre-positioning the locking member to engage with the supporting member before any loosening can occur. The elastic member is pre-compressed to continuously push the locking member against the supporting member, preventing loosening before it can happen
2Reliability
If a locking device is added to prevent loosening, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The locking device merges multiple functions into a single integrated mechanism. The locking member, elastic member, and triggering member work together as one unified system that combines locking, latching, and release functions, reducing the need for separate components
Solution Approach 2:
The locking device is segmented into distinct functional components (locking member, elastic member, triggering member) that can be independently analyzed and manufactured, yet work together as a cohesive system. This segmentation allows for simpler individual parts that are easier to produce and maintain
3Reliability
If a locking mechanism is implemented to secure the holder, then the safety is enhanced, but the ease of operation between folded and unfolded states may be reduced
Solution Approach 1:
The triggering member serves as an intermediary between the user and the locking mechanism. By providing a dedicated triggering member with a triggering end, the system mediates the interaction between user input and the locking/unlocking action, making operation intuitive and easy while maintaining security
