Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional correction tape devices are limited by their inability to significantly adjust the operating angle, leading to inconvenience and potential damage due to uneven force distribution and insufficient supporting structures.
Innovation Solution
An automatic rotation type correction tape structure featuring a tubular outer casing, a movably installed inner casing with engaging structures, a tape delivery module with winding wheels and an oblique tape guiding spout, and a pressing device that allows the tape guiding spout to adjust its angle to match the user's posture, ensuring smooth rotation and improved usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a plate structure with a pivot portion is used to allow axial rotation of the tape delivery module, then the using angle can be adjusted, but the rotation becomes unsmooth and the service life is reduced due to insufficient supporting effect at the contact position
Solution Approach 1:
The patent transforms the static plate structure into a dynamic solution by introducing a resilient member that allows the support surface to deform elastically under pressure. This enables the tape delivery module to rotate smoothly while maintaining reliable support, as the resilient member absorbs stress and prevents structural failure at the contact position.
Solution Approach 2:
The patent changes the physical parameter of the support structure by replacing a rigid plate with a resilient member that can change its stiffness characteristics. The resilient member provides adequate support during rotation while accommodating the dynamic loads, thereby extending the service life of the correction tape device.
2Ease of operation
If force is applied to press the tape guiding spout to adjust the axial rotating angle, then the using angle changes to fit user posture, but the contact position receives the largest force causing structural weakness
Solution Approach 1:
The patent applies local quality by placing the resilient member specifically at the contact position where the largest force is received. This localized solution provides enhanced strength and support exactly where needed, while the rest of the structure maintains its original design. The resilient member absorbs the concentrated force, preventing structural failure at this critical location.
3Ease of operation
If the tape delivery module is axially movable in the outer casing to enable automatic angle adjustment, then user convenience is improved, but the device complexity increases
Solution Approach 1:
The patent implements self-service by designing the tape delivery module to automatically adjust its angle through resilient support rather than requiring complex control mechanisms. The resilient member naturally deforms under user pressure to enable rotation, and the module self-regulates its position without needing motors, sensors, or electronic controls, thereby maintaining simplicity while achieving automatic angle adjustment.

AI summary
An automatic rotation type correction tape structure comprises an outer casing, an inner casing and a tape delivery module. The outer casing has an opening and a circular top abutting surface formed inside the outer casing and proximate to the opening. The inner casing is movably installed in the outer casing and has an engaging structure corresponding to the inner casing, such that the inner casing can be rotated axially with respect to the outer casing. The tape delivery module is installed in the inner casing and has a tape guiding spout at an end of the tape deliver module. When use, the tape guiding spout is pressed to drive the inner casing to rotate axially in the outer casing in order to adjust an operating angle and improve the convenience of the use.
