Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional flat work surface is used, then the device complexity is low, but the ergonomics and posture support deteriorate leading to increased stress and eye strain
Solution Approach 1:
The slant board introduces a dimensional change by elevating the work surface at a specific angle (approximately 25 degrees), transforming the conventional flat horizontal surface into an inclined plane. This angular elevation repositions the work surface in three-dimensional space, allowing the user's eyes to be level with the text and materials while maintaining proper posture, thereby resolving the ergonomic contradictions without requiring complex active mechanisms
Solution Approach 2:
The invention applies parameter changes by specifying a precise angular parameter (approximately 25 degrees) for the board's inclination and adjusting the height of the support structure. These quantitative parameter modifications optimize the geometric relationship between the work surface and the user's body, achieving improved ergonomics through controlled changes in angle and elevation rather than through complex mechanical systems
2Object-affected harmful factors
If reading material is placed on a flat surface, then the setup is simple, but eye strain increases due to constant refocusing and perspective changes
Solution Approach 1:
By elevating the reading material to a higher vertical plane through the inclined board, the user's line of sight becomes level with the text rather than looking down. This dimensional repositioning eliminates the need for constant refocusing and perspective adjustment, reducing eye strain while maintaining a simple static structure without complex mechanisms
3Object-affected harmful factors
If writing or typing is done on a flat surface, then the setup is simple, but wrist strain and fatigue increase due to improper posture
Solution Approach 1:
The inclined board elevates the writing or typing surface to a higher plane, allowing the user's forearms to rest naturally on the board while the hands position themselves comfortably for writing or keyboard use. This angular elevation aligns the wrists in a neutral position, reducing strain and fatigue without requiring complex adjustable mechanisms or active components
Solution Approach 2:
The invention optimizes wrist ergonomics by changing the angular parameter of the work surface to approximately 25 degrees and adjusting the height parameter of the support structure. These quantitative modifications create an optimal geometric configuration that naturally positions the wrists in a strain-free posture, achieving ergonomic improvement through parameter optimization rather than complex mechanical adjustments
4Stability of the object's composition
If the slant board uses adjustable legs for stability, then the stability is improved, but the ease of storage deteriorates
Solution Approach 1:
The support structure is segmented into adjustable legs that can be independently positioned and locked at different angles. This segmentation allows the legs to be extended and locked for stable use, then folded back against the board for compact storage, resolving the contradiction between stability and storage ease through modular, movable components
Solution Approach 2:
The legs incorporate dynamic characteristics by being movable and adjustable rather than fixed. They can be extended and locked into position for stable use, then collapsed back against the board for compact storage. This dynamic design allows the structure to transition between stable operational state and compact storage state, resolving the contradiction between stability and ease of storage
