Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a fastener is provided in the conveyance belt for easy attachment, then the efficiency of replacing the conveyance belt is improved, but irregularity is formed in the conveyance belt which reduces conveyance accuracy
Solution Approach 1:
The patent removes the fastener component from the conveyance belt design. Instead of incorporating fasteners into the belt itself, the invention uses a separate attachment mechanism that engages with the recording apparatus housing, thereby eliminating the source of irregularity while maintaining ease of replacement.
Solution Approach 2:
Rather than attaching the conveyance belt directly to itself or to the medium support surface using fasteners, the invention inverts the approach by having the conveyance belt engage with protrusions on the housing that extend into recesses in the belt, reversing the traditional fastening direction and eliminating irregularities.
2Ease of operation
If the conveyance belt is welded without positioning parts, then the operation is simpler, but the welding quality and alignment may be poor
Solution Approach 1:
The positioning parts are pre-installed on the housing before the conveyance belt attachment process. These positioning protrusions and recesses are manufactured in advance to ensure precise alignment, eliminating the need for complex positioning operations during belt replacement while maintaining high welding quality.
3Reliability
If heating is applied to the entire conveyance belt, then welding is more reliable, but unnecessary heat application reduces efficiency and may damage the belt
Solution Approach 1:
The heating mechanism is designed to apply heat locally only to the welding portions of the conveyance belt where the end portions are joined, rather than heating the entire belt. This localized heating approach maintains welding reliability while improving efficiency and preventing damage to non-welding areas of the belt.
