Innovation Solution
An adjustable slide latch device with a stopper device comprising a stopper piece, an adjustment piece, and a limit piece, allowing for adjustable spacing between thrust blocks to accommodate varying drawer weights, enabling convenient use and reduced production costs by adjusting the force required to open or close drawers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple positioning device designs are used to accommodate different drawer weights and volumes, then the adaptability to different drawer types is improved, but the device complexity and manufacturing costs increase
Solution Approach 1:
The positioning device incorporates an adjustable mechanism that allows the positioning member to be moved along the track to different positions. This dynamic adjustment capability enables a single device design to accommodate various drawer weights and volumes by changing the positioning position, eliminating the need for multiple fixed-position positioning devices for different drawer types.
Solution Approach 2:
The invention changes the position parameter of the positioning member along the track to adapt to different drawer configurations. By allowing continuous or discrete adjustment of the positioning position, the system can optimize the positioning force application point based on the specific drawer weight and volume, providing versatility without requiring multiple device variants.
2Adaptability or versatility
If multiple positioning device designs are used to accommodate different drawer weights and volumes, then the adaptability to different drawer types is improved, but the manufacturing costs and inventories increase
Solution Approach 1:
The positioning device is designed as a universal mechanism that can serve multiple drawer types through adjustment. Instead of manufacturing separate positioning devices for light drawers, medium drawers, and heavy drawers, this single adjustable design performs all functions, reducing manufacturing complexity, inventory requirements, and production costs while maintaining full adaptability.
Solution Approach 2:
The adjustable positioning mechanism transforms a static, application-specific device into a dynamic, multi-purpose tool. This eliminates the need for manufacturers to maintain multiple product lines and inventories, as one adjustable device can be configured for any drawer type, significantly reducing manufacturing costs and inventory management complexity.
3Device complexity
If fixed positioning devices are used on tracks, then the device complexity is reduced, but the reliability under excessive loads decreases
Solution Approach 1:
The adjustable positioning device allows the positioning position to be optimized based on the actual load conditions. When excessive loads are anticipated, the positioning member can be moved to positions that provide better mechanical advantage or distribute forces more effectively, enhancing reliability without requiring a fundamentally more complex device architecture.
Solution Approach 2:
By allowing adjustment of the positioning position parameter, the system can adapt to different load conditions. For heavier loads, the positioning member can be positioned to maximize structural support and minimize stress on critical components, thereby improving reliability while maintaining a relatively simple device design.
4Reliability
If positioning devices are designed for specific drawer weights, then the reliability for those specific weights is improved, but the adaptability to other drawer types decreases
Solution Approach 1:
The adjustable positioning mechanism allows the device to be dynamically reconfigured for different drawer weights. Instead of being fixed for a specific weight range, the positioning member can be moved to optimize performance for light, medium, or heavy drawers, maintaining high reliability across all weight categories while achieving full adaptability.
Solution Approach 2:
The invention creates a universal positioning device that can reliably serve multiple drawer weight categories through adjustment. By incorporating the adjustment mechanism, the device achieves multi-functionality, providing reliable positioning for specific weights when needed while also adapting to other drawer types, thus resolving the trade-off between specialization and versatility.

AI summary
An adjustable slide latch device has a slide track unit comprising an outer track and an extendable and retractable inner track held in the outer track, both are collectively provided with (a) a stopper device comprising a stopper piece and an adjustment piece and (b) a limit piece at laterals: the stopper piece disposed at the surface of the inner track comprises base parts which are fixed on the inner track and have (1) equidirectional-extended support arms at both laterals on which there are thrust blocks at rear ends and (2) positioning parts between two support arms; the adjustment piece which is disposed at the stopper piece's other lateral away from inner track and has a pivot part joining the positioning parts can drive two support arms during rotation to adjust space between thrust blocks at two support arms' rear ends and change forces to open and close a drawer.
