Compact Belt Installation Jig Using Captive Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing belt installation jigs are bulky due to the need for an attachment unit to maintain stability, and they are complex to connect with pulleys, making them difficult to use in space-limited environments and complicating the orientation during belt installation.
Innovation Solution
A belt installation jig with a body featuring a pulley pressing part, a belt holding part, and a belt pressing part, which is placed in an initial operating state where the belt is wrapped around pulleys, allowing the jig to be maintained by captive interaction with the belt and pulleys, eliminating the need for additional attachment structures and enabling compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If an attachment unit is used to maintain the belt installation jig stably in a desired attitude, then the stability is improved, but the overall size of the jig increases
Solution Approach 1:
The invention extracts and eliminates the attachment unit from the belt installation jig system. The jig is designed to be used without any attachment to the pulleys, removing the need for complex connecting structures while maintaining operational stability through the jig's interaction with the belt and pulley geometry during the installation process.
Solution Approach 2:
The belt installation jig utilizes the belt and pulleys themselves to maintain its position and stability during operation. The jig is held in the desired attitude by the captive interaction between its components and the belt-pulley system, rather than requiring separate attachment mechanisms. The system serves itself by using the objects being manipulated to support the installation tool.
2Stability of the object's composition
If an attachment unit is used to connect the belt installation jig to the pulley, then the stability is improved, but the device complexity increases
Solution Approach 1:
The invention removes the attachment unit entirely from the system. The belt installation jig is designed to operate independently without any connection to the pulleys, eliminating the complexity of designing, assembling, and operating complex connecting structures while maintaining stability through the jig's geometric interaction with the belt and pulley.
Solution Approach 2:
The stability and orientation of the belt installation jig are achieved through the captive interaction between the jig components and the belt-pulley system during installation. The system uses itself to maintain stability, with no external attachment structures required, thereby eliminating device complexity.
3Volume of moving object
If a compact design is used for the belt installation jig, then the space requirement is reduced, but the stability during operation may be compromised
Solution Approach 1:
By removing the attachment unit, the invention achieves a compact design that fits in limited spaces without requiring bulky connecting structures. The compact jig maintains stability through its functional interaction with the belt and pulley during installation, proving that compactness and stability are not mutually exclusive when the attachment unit is eliminated.
Solution Approach 2:
The compact belt installation jig maintains operational stability by being held in the desired attitude through captive interaction with the belt and pulleys during the installation process. The system uses the objects being manipulated to provide stability, allowing a compact design to achieve both space efficiency and operational stability.

AI summary
The combination of: a) first and second spaced pulleys; b) an endless belt; and c) a belt installation jig having a body with: a pulley pressing part; a belt holding part; and a belt pressing part. The belt installation jig and belt cooperate so that with the belt operatively wrapped against the second pulley and partially operatively wrapped against the first pulley, turning of the first pulley causes the belt to progressively wrap around the first pulley to a fully operatively wrapped state, whereupon further turning of the first pulley situates the belt installation jig for separation from the belt and pulleys.
