Solution Overview
Problem
Existing binding technologies face challenges in efficiently pushing a bundle of recording materials in the thickness direction without a complex configuration and in effectively removing paper dust from pressing parts, which can lead to hardened dust deteriorating the binding function.
Innovation Solution
A binding apparatus with a set of binding parts that press and bind the bundle from both sides, supported by first and second support parts rotating around a fulcrum, and a cleaning mechanism using brush-like structures to remove paper dust from the binding parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sheet pushing part is used to push the bundle of recording materials in the thickness direction, then the binding stability is improved, but the device complexity increases due to the complicated configuration required for linear movement
Solution Approach 1:
Instead of pushing the bundle from above with a complex linearly moving sheet pushing part, the invention pushes the bundle from below using the lower frame. This inverted approach simplifies the configuration while achieving the same binding stability effect by utilizing the natural movement of the binding unit and adding a simple protruding member to the lower frame.
Solution Approach 2:
The protruding member on the lower frame acts as an intermediary that transfers the pushing force to the bundle of sheets. When the binding unit moves into the accumulation region, the protruding member pushes the bundle upward, achieving the required thickness direction movement without complex mechanisms.
2Reliability
If idling operation is used to remove paper dust from the pressing part, then the binding function is maintained, but paper dust may remain on the pressing part when teeth are engaged, leading to hardened dust
Solution Approach 1:
The invention extracts the cleaning function from the pressing part itself and implements it separately through brush members. The brush members are positioned to contact the pressing part during the binding operation, actively removing paper dust rather than relying on passive idling operations, thereby preventing dust accumulation and hardening.
3Reliability
If the lower frame supports the bundle of sheets during binding, then the binding stability is improved, but the protruding member needs to separate the bundle from the lower frame, adding operational complexity
Solution Approach 1:
The invention merges the support function and the separation function into a single integrated lower frame structure. The protruding member that provides support during binding also automatically performs the separation function when the binding unit retreats, eliminating the need for separate operational steps and reducing operational complexity.
