Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing arc-shaped locks for LED display assemblies cannot adjust the angle between adjacent cabinets in a small range, failing to meet customer demands for precise adjustments.
Innovation Solution
An arc-shaped adjustment lock featuring a base with a first arc-shaped portion and an adjustment component with a second arc-shaped portion, using a staggered double V-shaped groove group and elastic beads for precise sliding and locking, along with a pressing lock assembly and quick-lock assembly to achieve fine-tuned angle adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing arc-shaped locks are used to connect LED cabinets, then the angle between adjacent LED cabinets can be adjusted in a wide range, but the adjustment precision is insufficient and cannot meet customer demands for small range adjustments
Solution Approach 1:
The arc-shaped groove is segmented into multiple discrete positioning positions along the arc, allowing the elastic bead to engage with specific segments for precise angular adjustment. The groove structure is divided into multiple V-shaped grooves at different angular positions, enabling step-by-step precise positioning rather than continuous adjustment.
Solution Approach 2:
The arc-shaped groove has different local characteristics at different positions - some regions have denser V-shaped grooves for fine adjustment, while other regions have sparser grooves for coarse adjustment. The elastic bead interacts with different groove densities at different angular positions to achieve both precision and range.
2Measurement precision
If a complex locking mechanism is added to achieve precise angle adjustment, then the adjustment precision improves, but the device complexity increases
Solution Approach 1:
The elastic bead automatically engages with the V-shaped grooves through elastic deformation, achieving self-locking without requiring additional locking components. The elastic force of the bead itself provides the locking mechanism, eliminating the need for complex external locking devices while maintaining positioning precision.
Solution Approach 2:
The elastic bead acts as an intermediary between the arc-shaped groove and the positioning requirement. It transforms the geometric constraint of the V-shaped groove into a mechanical locking force through elastic deformation, simplifying the overall locking mechanism while achieving precise angular positioning.
3Ease of operation
If the arc-shaped lock structure is simplified for easy operation, then the ease of operation improves, but the locking reliability may be compromised
Solution Approach 1:
The elastic bead provides automatic engagement and locking when the arc-shaped components are moved into position. The elastic deformation of the bead creates a self-locking mechanism that maintains the adjusted angle without requiring additional fastening operations, ensuring both ease of operation and locking reliability.
Solution Approach 2:
The arc-shaped groove and elastic bead geometry utilize curved surfaces to guide the engagement process. The V-shaped grooves are arranged along an arc, and the elastic bead's spherical shape allows it to naturally follow the curved path and engage with the grooves, providing intuitive and reliable locking through geometric constraints rather than complex mechanical features.
