Tape Holder Gravity Displacement for Sheet Binding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sheet binding devices lack a simplified mechanism for binding a sheet bundle with adhesive tape, requiring complex structures and increased costs.
Innovation Solution
A sheet binding device incorporating a tape support base, a movable tape holder, and displacement mechanisms that allow the tape holder to transition between positions for efficient tape attachment to a sheet bundle, utilizing a first displacement mechanism to move the tape holder from a raised to a lowered position for tape reception and a second mechanism to retract it, eliminating the need for a dedicated driving source and simplifying the mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex mechanism is used to bind sheet bundles with adhesive tape, then the binding function can be achieved, but the device size and cost increase
Solution Approach 1:
The tape holder is designed to automatically move to the lowered position when it approaches the tape support base, utilizing its own weight and gravity to perform the displacement action without requiring an external driving source or complex control mechanism
Solution Approach 2:
The patent removes the dedicated driving source (motor or actuator) from the system, extracting the unnecessary complexity while retaining the essential binding function through the self-displacing tape holder mechanism
2Manufacturing precision
If a dedicated driving source is added to move the tape holder, then the tape attachment precision improves, but the device complexity and cost increase
Solution Approach 1:
The tape holder uses its own weight and the gravitational force to automatically displace to the lowered position, eliminating the need for external driving sources while maintaining precise positioning through the self-displacing mechanism
Solution Approach 2:
The mechanism utilizes gravitational potential energy conversion, allowing the tape holder to move from a higher position to a lower position naturally, achieving precise positioning without additional energy input or complex control systems

AI summary
According to one embodiment, a sheet binding device includes a tape support base, a tape holder, and a first displacement mechanism. The tape support base supports a tape. The tape holder is movable in a first direction. The first displacement mechanism displaces the tape holder from a first position that is a position away from the tape to a second position at which the tape holder is capable of coming into contact with the tape when the tape holder moves toward the tape support base and receives the tape.
