Button-Release Lacing Buckle for Hands-Free Tightening and Loosening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lacing buckles require manual operation by bending over to loosen or retract laces, and their complex structures are prone to damage from repeated use.
Innovation Solution
A pressing and rotating lacing buckle with a fastening seat, take-up wheel, reset spring, transmission wheel, and button mechanism that allows for one-way rotation and locking, enabling lace tightening and loosening through simple button presses without bending over.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If radially actuated covers with clutch structure are used to switch between loosening and retracting, then the lacing buckle can achieve tightening and loosening functions, but the structure becomes complex and prone to damage from repeated use
Solution Approach 1:
The patent extracts and eliminates the complex clutch structure from the lacing buckle, replacing it with a simpler button-press mechanism that directly actuates the take-up wheel. This removal of unnecessary components reduces structural complexity while maintaining the essential tightening and loosening functions through a more durable design.
Solution Approach 2:
Instead of using a radial cover actuation mechanism that requires bending over, the patent inverts the operation mode to use a button-press action that can be performed hands-free. This inversion changes the fundamental interaction mode from manual manipulation to simple pressing, reducing operational complexity and improving accessibility.
2Adaptability or versatility
If radially actuated covers are used for loosening and retracting laces, then the lacing buckle can perform its function, but the user must bend over and manually operate it
Solution Approach 1:
The patent implements a button-press mechanism that allows the lacing buckle to be operated without manual manipulation of covers. The button can be pressed with the foot or other body parts, enabling hands-free operation and eliminating the need to bend over. This self-service approach improves ease of operation by allowing users to adjust laces while seated or in positions where bending would be inconvenient.
3Adaptability or versatility
If complex clutch structures are used in lacing buckles, then tightening and loosening can be achieved, but the structure is prone to damage from repeated pulling
Solution Approach 1:
The patent removes the vulnerable clutch structure from the design, replacing it with a more robust button-actuated mechanism. This extraction eliminates the weak point in the system that was prone to damage from repeated pulling, while maintaining the full tightening and loosening functionality through a more durable mechanical arrangement.
Solution Approach 2:
The patent incorporates a reset spring that provides cushioning and shock absorption in the button actuation mechanism. This spring element protects the mechanical components from damage caused by repeated pressing and pulling actions, enhancing the overall reliability and durability of the lacing buckle under repeated use.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates easy and stable lace management by allowing hands-free operation and reducing structural complexity, enhancing user convenience and durability.
Implementation Method 1
a reset spring, a transmission wheel, and a cap are sequentially disposed on the take-up wheel; the cap is configured to drive the take-up wheel to rotate within the take-up seat via the transmission wheel; a button is disposed on the cap; when being pressed, the button acts on the transmission wheel and compresses the reset spring, to release and reset a connection between the cap and the take-up wheel

AI summary
A pressing and rotating lacing buckle, including a fastening seat (10) disposed on a shoe upper, shoe tongue, shoe heel, clothing, hat, or bag; where a take-up seat (20) is disposed on the fastening seat (10); a take-up wheel (30) is disposed in a take-up cavity (21) within the take-up seat (20); a reset spring (40), a transmission wheel (50), and a cap (60) are sequentially disposed on the take-up wheel (30); the cap (60) is configured to drive the take-up wheel (30) to rotate within the take-up seat (20) via the transmission wheel (50); a button (70) is disposed on the cap (60); when being pressed, the button (70) acts on the transmission wheel (50) and compresses the reset spring (40), to release and reset a connection between the cap (60) and the take-up wheel (30). The cap (60) drives the take-up wheel (30) by means of the transmission wheel (50) to rotate in the take-up seat (20), and when being pressed, the button (70) acts on the transmission wheel (50) and compresses the reset spring (40), to release and reset the connection between the cap (60) and the take-up wheel (30). Therefore, the winding locking state of a lacing buckle can be switched or released simply by means of the button (70), and the button (70) can be pressed even by means of two feet or cooperation of the feet and other objects on the ground, thereby freeing both hands and avoiding a stooping operation, and improving the user experience.
